and [Hydrobia] schmidtii (Charp.), Valvata cristata, Miill, Anodonta eellensis
(Gmel), and Pisidium amnicum (Miill.); the absence of the larger species of
Limncea and Paludina is highly characteristic of the mountainous region.
Among the land-shells Central-European species are mixed with others peculiar
to the southern slope of the Alps, for example Helix incarnata,
fruticum, obvoluta, with cingulata, angigyra, cemula, and others. Some errors
in the former paper of the same author are here corrected.
Verona. E. DE BETTA enumerates 153 species of Mollusca living in the
Province of Verona, 92 of which are terrestrial, the rest freshwater. Many
of these are real novelties for this fauna, as:— Vitrina brevis (Fer.), on the
Montebaldo; Zonites hyalinus (Fer.), hydatinus (Rossm.), Helix lurida,
Ziegl, cemula, Rossm., Bithynia ventricosa, Gray, &c. The genera and subgenera
are carefully characterized and critical remarks appended to the species.
The existence otMelania holandri (Fer.) within the province has not received
confirmation, and it is probably to be cancelled.
Venice. E. DE BETTA comprises 138 land, 70 freshwater, and 6 submarine
species, viz. two Auriculidee and four Hydrobice, which he wrongly calls
Bithynia. As the province extends from the Alps to the sea, we find
among them species which are peculiar to the mountains, and especially to
those of Friul and part of Carniolia, as Helix intermedia, Fer., cemula,
Rossm., phalerata, Ziegl, lurida, Ziegl, leucozona, Ziegl., ClausUia costata,
Ziegl, cincta (Brumati) ; others more peculiar to Lombardy, as H angigyra
(Jan), TJnio bonelli (Fer.); and some characteristic of the seashore, as Helix
pisana, Miill, trochoides, Poir., &c. The genus Clausilia is represented
by 22 species, Pupa, including Vertigo, by 15, Neritina by 9 species. 1st.

Thirty-one species of land-shells collected by A. Issel at Tabiano near
Parma, and 15 found by Prof. Trinchese at Lecce near Salento, are enumerated
by the former, Bull. mal. Ital. iii. pp. 167-169.
The stray notes concerning land and freshwater shells of the continent of
Middle and Southern Italy are collected and arranged geographically by E.
v. Martens in an appendix to Bull. mal. Ital. iii. 1870, to which the editor,
C. Gentiluomo, has added some introductory and bibliographical remarks.
JJmbria. Thirty-one species of land and 3 freshwater shells, collected by
G. BELLUCCI near Terni and Pervigia, are enumerated, Bull. mal. Ital. iii.
pp. 113-118. The most remarkable among them are Helix hispana, L.
[planospira, Lam.], strigata, Miill., Clausilia leucostigma, var. opalina, Ziegl,
and C.piceata, Ziegl, Bithynia boissieri (Charp.), and Planorbis subangulatus,

Tuscany. The occurrence of Melanopsis dufourei, Fer., ascertained by
F. L. Appelius, Nach. mal. Ges. p. 44.
Rome. Twenty-four species of land- shells, collected by GUST. MANTOVANI
in the vicinity of Rome, including the Alban hills and the valley of the Anio,
are enumerated by GENTILUOMO (Bull. Mal iii. pp. 41-43). The most remarkable
are:—Zonites candidissimus (Drap.), Monte Mario, only one specimen
; Helix ligata, Miill. [gussoneana, Shuttl], Monte Sacro, Monte Mario,
Subiaco and Frascati; Helix nemoralis, the variety in which all five bands
are confluent, only at Subiaco, but abundant; setipila, Zeigl, Subiaco and
Tuscolo near Frascati; strigata, Miill., Subiaco; Clausilia piceata, Ziegl.
