centered to the left of the midline; and 4) a male (114 mm CL; 105mm PL) with a hump between V1 and V2; spine laterally curvedat hump; scutes V1–V5 were deformed.Only 5 of the 235 (2.1%) adult and subadult specimens examinedin our study exhibited noticeable kyphosis or kyphoscoliosis,and only one (0.4%) was markedly abnormal. We observed nospinal deformities in any hatchlings (N = 123) obtained from gravidfemales captured in the study area (Stuart and Painter 2006.Herpetol. Rev. 37:79).Within the genus, kyphosis or related spinal deformities havebeen reported in T. scripta scripta (Carr 1952. Handbook of Turtles:The Turtles of the United States, Canada, and Baja California.Cornell Univ. Press, Ithaca, New York), T. s. elegans (Tucker etal. 2007. Herpetol. Rev. 38:337–338), T. s. troostii (Cagle 1950.Ecol. Monog. 20:31–54), and T. yaquia (Plymale et al. 1978. Southwest.Nat. 23:457–462). Tucker et al. (op. cit.) found kyphosis inonly 0.06% of all T. s. elegans (N = 21,786) they captured in Illinoisbut noted that higher rates of occurrence (< 2.6%) have beenreported in other turtle species based on much smaller sample sizes.Our report is the first for spinal deformities in T. gaigeae and suggeststhat its occurrence is also uncommon in this species.We thank C.

Box 25112,Santa Fe, New Mexico 87504, USA.SQUAMATA — LIZARDSABRONIA TAENIATA (Bromeliad Arboreal Alligator Lizard).MICROHABITAT. Lizards of the genus Abronia (Anguidae) displayboth morphology and behavior specialized for arboreality(Campbell and Frost 1993. Bull. Am. Mus. Nat. Hist. 216:1–121).The genus also appears to be among the most endangered of Neotropicalsquamate lineages, and several species are known fromonly one or a few specimens (Campbell and Frost, op. cit.). Inaddition, species of Abronia are secretive (Formanowicz et al. 1990.Biotropica 22:391–396), and probably exhibit naturally low densities,though detailed information on population size is difficultto obtain in their arboreal habitats. Consequently, observations ofAbronia are rare, and few reports describe activity in terrestrialenvironments (Martin 1955. Copeia 1955:173–180; Campbell andFrost, op. cit.). Abronia taeniata is a relatively widespread Mexicanspecies that occurs in the pine-oak forests of the Sierra MadreOriental between 1000–3000 m (Martin 1958. Misc. Publ. Mus.Zool. Univ. Michigan 101:1–102). Terrestrial habitat use in thistaxon has been infrequently reported, with little information availableon associated behavior (Martin 1955, op. cit.). Here, we providetwo additional observations of terrestrial activity in this speciesfrom the state of Hidalgo.At 1545 h on 1 July 2006, BPS, ELMV, and NI found an adultfemale A. taeniata (83.9 mm SVL, 116.5 mm tail, 10.7 g) in thecrevice of a large limestone boulder (20.8778°N, 99.2299°W, datum:WGS84; elev. 2464 m) under pine (P. greggii/P. patula)-oak(Q. crassipes) forest canopy near the community of La Manzana,in Parque Nacional Los Mármoles (PNLM). The observation wasmade following strong morning rains. On our approach, the A.taeniata retreated into the boulder, but we captured it at 1645 hafter it reappeared at the edge of the same crevice. The nearesttree (a mature pine, probably P. greggii) was ca. 1.5 m away.Elsewhere in the range of A. taeniata, the species has been collectedin trees (Martin 1958, op. cit.). Other species of Abroniahave been collected on tree trunks, and in epiphytic bromeliadsand mosses (Campbell and Frost, op. cit.). In the Los Mármolesregion, however, mature trees support few large epiphytes (BPS,pers. observ.), so A. taeniata may use terrestrial refugia in thisarea with greater frequency, at least during inclement weather. Thespecimen (BPS-CIB 24) was deposited in the vertebrate collectionsof the Centro de Investigaciones Biológicas (CIB) at theUniversidad Autónoma del Estado de Hidalgo.At 1030 h on 29 March 2007, IECS also found an adult femaleA. taeniata (106.8 mm SVL, 143.0 mm tail, 19.0 g) on leaf litterin a pine (P. rudis)-oak (Q. rugosa) forest at Campamento Conejoin Parque Nacional El Chico (20.1877°N, 98.7097°W, datum:WGS84; elev. 2915 m). The lizard was found in a patch of forestfloor illuminated by morning sunlight; the nearest trees were 2–3m away. IECS observed it for ca. 15 min, then captured it for depositioninto the CIB vertebrate collection (specimen: ARP-00109).We thank A. Leyte Manrique for logistical assistance. JonathanA. Campbell (University of Texas, Arlington) confirmed the PNLMrecord as A. taeniata. We thank SEMARNAT and SRE (Governmentof Mexico) for providing collecting permits, and the Municipalityof Zimapán and the Bienes Comunales of La Encarnaciónfor providing additional logistic support.

DIET. Ameivaexul has a diverse diet that includes invertebrates (earthworms,snails, insects, crabs), vertebrates (frogs, lizards), vegetable matter(banana, apple, cactus fruits), dog food, and even certain typesof garbage (Joglar [ed.] 2005. Biodiversidad de Puerto Rico–Vertebrados Terrestres y Ecosistemas. Editorial del Instituto deCultura Puertorriqueña, San Juan. 563 pp.; Lewis 1989. J. Herpetol.23:164–170; Rivero. 1998.
