and \_IIydrohia] schmidtii (Oharp.), Valvata cristatay Miill., Anodonta cellensis 
(Qmel.), and IHsidium amnicum (Miill); the absence of the larger species of 
Limncca and Faludina is highly characteristic of the mountainous region. 
Among the land-shells Central-Eiiropean species are mixed with others pe- 
culiar to the southern slope of the Alps, for example Helix incarnata, 
fruticrim, ohvolida, with cingxdata, angigyra, cermday and others. Some errors 
in the former paper of the same author are here corrected. 
Vci'ona. E. de Betta enumerates 153 species of Mollusca living in the 
Brovince of Verona, 92 of which are terrestrial, the rest freshwater. Many 
of these are real novelties for this fauna, as: — Vitrina brevis (Fer.), on tho 
Montebaldo; Zonites hyalmus (Fer.), hydatimis (Rossm.), Helix luriday 
Ziegl., ccimda, llossm., Bithynia ventricosay Gray, &c. The genera and sub- 
genera are carefully characterized and critical remarks appended to the species. 
The existence of Melania holmidri (F^r.) 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 Hydrohice, 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, 
Bossm., yhaleratay Ziegl., lurida, Ziegl., leucozona, Ziegl., ClaiisUia costata, 
Ziegl., cincta (Brumati) ; others more peculiar to Lombardy, as II. angigyra 
(.Jan), JJnio honelli (Fer.) ; and some characteristic of the seashore, as ilelix 
jusana, 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 16 found by Prof Trinchese at Lecce near Salento, are enu- 
merated by the former. Bull. mal. Ital. iii. pp. 167-1G9. 
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, 
0. Gentiluomo, has added some introductory and bibliographical remarks. 
Umbria. Thirty-one species of land and 3 freshwater shells, collected by 
G. Bellucci near Terni and Perugia, are enumerated. Bull. mal. Ital. iii. 
pp. 113-118. The most remarkable among them are Ilelix liispana, L. 
[planospira, Lam.], strigata, Miill., Clausilia leucostigma, var. opalina, Ziegl., 
and C.piceata, Ziegl., Bithynia boissieri (Oharp.), and Plattorbis 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 GENTiiiUOMO (Bull. Mal. iii. pp. 41-43). The most re- 
markable arc: — Zonites candidissimus (Drap.), INlonte Mario, only one spe- 
cimen; Ilelix ligata, Miill. {iiussoneana, Shuttl.], Monte Sacro, Monte Mario, 
Subiaco and Frascati ; Ilelix 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.
