this effort, 7% of the 10 × 10 km units (chiefly in Basilicata andSardegna [Sardinia]) have no records for any species.A short chapter on altitudinal distribution presents data in theform of bar graphs by province and shows the results of a simplecluster analysis. Figure 4.1 (p. 142) would have been easier to usehad the areas mentioned been clearly indicated on the map.The final prelude to the accounts themselves is a checklist withtaxonomic remarks. Ninety-one species (40 amphibians and 51reptiles) inhabit Italian territory. The list is accompanied by extensiveendnotes that provide useful information on dates of publicationof names, ICZN rulings, recent generic allocations, andinstances of taxonomic confusion, conflict, or uncertainty in theItalian herpetofauna.The species accounts themselves begin with a convenient “howto read distributional maps” section. Each account except two ofthe sea turtles, Chelonia mydas and Dermochelys coriacea, andthe naturalized Red-Eared slider, Trachymys scripta, is accompaniedby full page, color, topographic map, marked with a half degreegrid. Plotted points are divided into 1984 and earlier records,1985 and later records from the SHI database, other records withoutspecific locality (some provinces provided only imprecise localitiesto protect the animals), and doubtful records. Account sectionsare: taxonomy (including phylogenetics), general distribution,comments on the distribution map (often very detailed), habitat,altitudinal distribution, annual activity cycle, reproduction, andstatus of populations in Italy. All accounts are illustrated by multiplecolor photos. For some species these include eggs, larvae orjuveniles, and views of courtship. In general the quality of thephotos is good—only a photo of the venter of Bombina pachypus(p. 274) appears out of focus. The provenance of most photos isnoted and the majority of photos actually depict Italian specimens.Chapter 7 by Corti, Lo Cascio, and Razzetti is an overview ofthe Italian island herpetofaunas. The island groups include the relativelyextensive island groups surrounding Sardinia and Sicily andoff the coast of Tuscany, as well as the smaller archipelagoes andislands of Liguria, Latium (the Pontine Islands), Venetia, and southernItaly (Campania, Basilicata, Calabria, and Apulia). An extensivetable provides species lists by island and a short text sectionoutlines relevant literature and taxonomic issues. The islands havea disproportionately high number of outstanding taxonomic problemsand conservation issues as many subspecies and even specieshave been described from them.Razzetti and Sindaco briefly discuss 15 additional unconfirmedtaxa that may or may not occur in Italy. Some are introductions(e.g., Xenopus laevis and Agama agama), whereas others approachthe borders of Italy and might eventually be added to the fauna(e.g., Rana arvalis and Pseudopus apodus). Most interesting isthe bizarre case of Rana osca, which the authors conclude is asynonym of R. italica—it was described multiple times, once inan unlocatable reference of uncertain date, and its type materialappears to have disappeared within a decade of its description.A biogeographic chapter by Bologna and Mazzotti reviews thegeological history of Italy from the mid-Tertiary onwards andemphasizes the diversity of spatial patterns reflected by theherpetofauna and the resulting biogeographic mosaic. Among thefaunal components recognized are widespread Euro-Asiatic elements,Western and Eastern Mediterranean forms, North Africanspecies, and peninsular, Sardinian, and Sicilian endemics. Of particularnote are taxa with affinities outside of Europe, e.g.,Speleomantes and Proteus, each with North American sister taxa.A variety of historical factors, including the Messinian salinitycrisis and glacial advance and retreat, are proposed to explain someof the observed affinities of the fauna. Italian endemism at thespecies level is especially high for amphibians (50%), whereasreptile endemism is lower (17%) and largely restricted to Sardiniaand Sicily, which are the most distinctive herpetofaunal regions ofthe country based on cluster analysis.The last two chapters deal with herpetofaunal conservation andlegislation. In Chapter 10, Roberto Sindaco evaluates the status ofthe Italian herpetofauna. Like most amphibians and reptiles worldwide,a lack of data regarding threats and population sizes necessitatescategorization based chiefly on areas of occupancy andhabitat fragmentation. All taxa are assigned to categories basedon this information as well as the proportion of the global range inItaly and, for endemics, the specific nature of their distribution(e.g., insular or mainland). In the following chapter Vincenzo Ferrioutlines the complex set of regulations than govern the protectionof the herpetofauna. This includes European, Italian, and provincialstatutes, some of which protect certain species and others ofwhich focus on habitat protection. Tables summarize the categorizationof each species under the Bern Convention, the EuropeanUnion Habitats Directive, and CITES. All species are covered underthe Bern Convention, and most by the Habitats Directive, but onlysea turtles, tortoises, and Vipera ursinii are CITES listed. Twentoneregional and provincial laws affecting amphibians and reptilesare also summarized.As is fitting for such a comprehensive volume, the bibliographyincludes more than 1500 references, a resource in itself, as notedby Benedetto Lanza in his preface to the book. In a welcome changefrom many recent books, a good deal of care seems to have beenpaid to bibliographic accuracy. Finally the book concludes withshort biographical sketches of the 54 authors who contributed tothe volume, photo credits, and a taxonomic index listing entriesby genus, species, and both English and Italian common name.Unfortunately, the references only relate to the species accountsproper; mentions in other chapters are not cited.Aside from the inadequacy of the index, I find little to criticizein this aesthetically attractive volume. Although my knowledge ofItalian is rudimentary, it appears that the English translation isfaithful. The information provided is up-to-date and I especiallyappreciate the fact that potentially confusing taxonomic and distributionalissues are explained and that the reader is lead to theoriginal literature throughout the book. This volume is a testamentto the vibrant herpetological community in Italy today. Inaddition to producing this atlas, the highly active SocietasHerpetologica Italica has also recently launched the predominantlyEnglish language journal, Acta Herpetologica. I highly recommendthe Atlas of Italian Amphibians and Reptiles to anyone withan interest in any aspect of the European herpetofauna.LITERATURE CITEDSOCIETAS HERPETOLOGICA ITALICA. 1996.

PAUWELSDépartement des Vertébrés RécentsInstitut Royal des Sciences Naturelles de BelgiqueRue Vautier 29, 1000 Brussels, Belgiume-mail: osgpauwels@yahoo.frNo synthetic work onHomalopsidae has been publishedsince the group’s revisionby the late Myanmar herpetologistKo Ko Gyi, which datesback to 1970. Much research hasbeen done since then, includingmany ecological and taxonomicstudies by Daryl Karns, John C.Murphy, Harold K. Voris andtheir collaborators. Several specieshave been described or revalidated,others synonymized,and after nearly four decades thetime is right for a new majorwork on these snakes. Taxonomically,the main recent contributorto the knowledge of this group is John C. Murphy, who(co-)described Enhydris chanardi, E. gyii, and E. vorisi. He is,thus, the best placed herpetologist to provide us with an overviewof the group, and his new opus is a very welcome contribution.The book includes two main parts, i.e., the introduction and keys(pp. 1–48) preceded by the preface and acknowledgments, andthe generic and specific accounts (pp. 49–212) followed by theliterature cited, appendices and the index to scientific names. Theauthor recognizes 10 genera and 37 species in the Homalopsidae,and adds a section on three homalopsid-like incertae sedis snakes(Anoplohydrus aemulans, Brachyorrhos albus, and B. jobiensis),which might eventually turn out to be homalopsids once detailedtaxonomic studies have been conducted.The introduction provides a well-written presentation of thegroup, its general ecology and classification. Figure 1 shows asnake phylogeny to help understand the homalopsids’ positionamong other snakes; its caption mentions that groups containingat least one aquatic representative are marked with an “A.” However,no A was associated to Grayia ornata, a strictly aquatic snake,nor to the Boidae, which however contain freshwater snakes suchas Eunectes murinus (see Pauwels et al., 2008 for a review of freshwatersnake diversity). The introduction also includes a chapterco-authored by Brooks et al. on the water snake harvest at TonléSap Lake, giving really impressive figures on the homalopsid meatand skin business in Cambodia.The identification keys include all homalopsid snakes, but unfortunatelynot the three incertae sedis ones. These keys are notfully reliable, since many ranges of characters provided are in contradictionwith those given in the species accounts. As an example,couplet 9a mentions that female Enhydris jagorii have more than50 subcaudals, while the species account (p. 134) says they have48–54 subcaudals, and that males have about 68, while the speciesaccount gives a variation of 53–68. Another example is thatcouplet 2a, “Nasal scales in contact” leads a.o. to Myronrichardsonii (couplet 4c), which actually has separated nasal scales,as rightly mentioned in its species account. I noted in total 34 suchdiscrepancies between the keys and the main text, with more-orlesssignificant consequences on species identification. It is alsoto be noted that there is no entry to couplet 9 of the key, excludingidentification of snake specimens identifiable as Enhydris jagoriiand E. longicauda. Consequently, an identification using these keysmust be carefully double-checked with a comparison of the specimento the presumably associated species account.The generic and species accounts are well constructed, with clearsections on etymology, species content, distribution, and diagnosis,and a partial chreso-synonymy. Each species account includesa partial chreso-synonymy and sections on etymology, commonnames, distribution, diagnosis (except Enhydris punctata), size,external morphology, habitat, diet and feeding behavior, reproduction,relationships, and on the museum material examined bythe author. In cases in which certain aspects of natural history areparticularly well known, additonal sections have been added(predators, etc.). The chreso-synonymies are most often incomplete;their literature references are mentioned using the authors,dates, and abbreviated titles. Since there is a literature section atthe end of the book, citing the authors and dates only in the chresosynonymywould have been sufficient and would have saved a lotof space. The external morphology section follows the same organizationfor all species and this is helpful for interspecific comparisons.A point locality map is provided for each species. Unfortunately,although there was an effort to track literature referenceseven in local journals, as stressed by Luiselli (2008) in his reviewof this book, many such references were not listed by the authorand numerous localities are thus missing from the maps of manyspecies, sometimes giving a misleading impression of rarity ordisparate populations.Most species are illustrated in life and in color—the book includes76 color photos. One species only, Brachyorrhos jobiensis,is not illustrated at all. There are also 38 black-and-white plates,each composed of six pictures, showing details of head or body.Additional illustrations, mainly drawings, are provided in 47 figuresthroughout the book, and there are often several drawings perfigure. The book is thus lavishly illustrated, most illustrations beingof very good quality. A number of specimen photographspresent important information, such as the only known picture ofa live Enhydris dussumieri, or a very unusually patternedHomalopsis buccata from Songkhla Lake, southern Thailand.Many photographs are accompanied by precise locality data, whichincreases their informational value. The natural history ofHomalopsidae is extremely interesting, and is well detailed foreach species: specialized diets and habitats, hunting strategies, etc.Typical biotope photographs are provided for a number of species.The main text often refers to the work of Gyi (1970), re-evaluatingthe accuracy of his observations and updating the data anddiagnostic characters for each species, indicating real progress in<strong>Herpetological</strong> <strong>Review</strong> 39(2), 2008 249
