GKOGRAPTTICAL DISTRIBUTION. 
Moll. 17 
variahilis^ troclioides^ acuta^ BuUmm tridens and qiiadridem, Pupa quin- 
que-dentata and granum, 5 species of Bithynia [Bithynella'] ; Drehsena 
polymorpha is now very common, but was not represented in Terver’s 
collection [it is of recent introduction]. Generally the fauna is that of 
the central mountainous parts of Europe, with some peculiarly Southern 
or Western additions. 
Thirty -eight terrestrial and 29 freshwater shells living near and in 
hot springs at Barbotan, dep. Gers, are enumerated by D. Dupuy, J. de 
Conch. XXV. pp. 15-23 ; among them, Pupa dilucida (Ziegl.) is new for 
France and Unio requiem has not yet been known to live in warm 
water. 
Toulouse. The Mollusks living near that city are reviewed and some 
wrong statements eliminated by M. P. Fagot, Bull. Soc. Toulouse, ix. 
[1875]. Generally, the fauna more nearly resembles that of Agen and 
the Gironde than that of Languedoc. Fischer, J. de Conch, xxv. 
pp. 313-315. 
2 . Sovthern Europe and Asia Minor. 
Pyrenees. 50 terrestrial and 2 freshwater species {Ancylus and 
Hydrohia') observed at Cauterets by P. Fischer, J. de Conch, xxv. 
pp. 49-56. 
Notes on the Mollusks of the Hautes-Pyr^ndes by M. P. Fagot and 
de Nansouty, in a pamphlet of 30 pp. without date ; see J. de Conch, xxv. 
pp. 312 & 313. 
Provence. 65 terrestrial and 11 freshwater species observed at 
Tiamalou-los-baius, dep. Herault, by Letourneux, R. Z. (3) v. pp. 
336-353. 
Helix telonensis and some allied species, some new, from the mountains 
of Southern France, described by Bourguignat, R. Z. (3) v. pp. 
232-249. 
Portugal. A. Morelet gives critical notes and additions to his “ De- 
scription des Mollusques terrestriales et fluviatiles du Portugal,” 
published in 1845. From 118 the number of species is increased, to 151, 
99 terrestrial, 49 freshwater, and 3 brackish water species. Unio loelwichi 
of the former publication is to be cancelled, being a foreign shell ; Helix 
candidula of the same is a variety of caperata (Mont.), Pupa secale = 
lusUanica (Rossm.), Clausilia rugosa = moniziana (Lowe), Planorbis 
corneus = metidjensis (Forbes), Unio tristis — margaritifer, juv. Among 
the additions, 4 only are not found elsewhere. Helix circumsessa 
(Shuttl.), is a Canarian species, found also at Oporto. J.| de Conch, 
xxv. pp. 242-261. 
Littoral Austria. The malacologica,! fauna of Gorz and Gradisca near 
the Adriatic is the subject of an interesting treatise by F. Erjavec, 
cited above ; he distinguishes five regions: (1) the Alpine, characterized 
by Vitrina diaphana. Helix phalerata and chamcdeon^ Pupa muscorum, var. 
madida^ Clausilia hergeri and succineata ; (2) the middle mountainous 
region, up to 1260 metres, agreeing mostly with the fauna of Carniolia ; 
(3) the plain of the Isonzo and the valley of Wippach, containing some 
1877 . [voL. XIV.] B 10
