MOLLUSCA. 
Belgian localities for land and fresh-water Mollusks noted by G. 
Collin, J. Colbeau, and E. van der Broeck, P.-v. Mai. Belg. 1874, 
pp. Ixiii., clxiii.-clxx., cxcix.-cci., and Ann. Mai. Belg. vii. (1873) pp. 21 
& 85. 
Brittany. J. Desmars has described 93 land and 65 fresh-water Mol- 
lusks (separate pamphlet, dated December, 1873), the more remarkable 
among which aro Geomalacus maeulosus, Liiuax gagatcs and soiverbii, 
Helix quimperiana, cornea, ohuoluta, fusca, limbata, plebeia, ponentina, 
ptilota (Bourg.), ignota (Mabille), arenosa (Ziegl.) [var. of ericetorum ?], 
cespitum, danieli (Bourg.), variahilis, submaritima, and lineata, 
Clausilia rolphi, druiditica (Bourg.), armoricana {Boavg.'), Pupa semproni, 
Physa taslii (Bourg.), subopaca (Lam.), Bythinia siniilis, Valvata 
minuta, Unio littoralis and requieni, Cyclas terveriana (Dnpuy), and 
Hreissena polymorpha, the last first observed in 1868.. 
The malacological faunae of the environs of Paris and of the depart- 
ment of the Ilaute-Loire, have been treated (1873) by L. Pascal, Arch. 
Miss. Sci. (3) i., abstracted in J. de Conch, xxii. pp. 399-401 ; he enume- 
rates 115 species in the former, and 82 in the latter locality. 
A list of land and fresh- water shells found in the granitic region of 
the Vosges mountains is given by G. Collin, P.-v. Mai. Belg. 1874, 
pp. xxvii.-xxxii. 
0. Reinhardt has treated the malacological fauna of the Sudetic 
Mou7itains (between Silesia, Bohemia, and Moravia) from personal re- 
searches made chiefly in the “ Iser-gebirge ” and “ Mahrisches Gesenke.” 
He enumerates 108 species, and notes for each its hypsometrical and 
geographical distribution. The fresh-water shells are very poor in 
species, and most of them occur only in the lower regions until 2000 feet 
above the sea ; Limncea peregra and the peculiar Pisidium roseum 
(Scholtz) only are found in the higher regions. In the western parts, 
there are some species of land-shells, which are to be considered as ad- 
vanced posts of the fauna of the Eastern Alpine province, viz. : — Helix 
holoserica and cobresiana, Clausilia oi'thostoma, Hyalina glabra ; in the 
eastern part, there are some species common with the Carpathian moun- 
tains, but not found in any other part of Germany ; these are Helix 
carpatica (Friv.) and H. faustina (Ziegl.). In the subalpine region of the 
whole chain, where no tree (or only Pinus pumilio) grows, the following 
23 species have been found: — Ai'ion subfuscus, hoi'tensis, Limax cinereus, 
marginatus, Vitrina elongata, pellucida, Hyalina I'adiatula, pura, nitidiila, 
fulva, Helix pygmcea, holoserica, arbastorum, Oionella lubrica. Papa eden- 
tula, alpestris, arctica, pusilla, Clausilia plicatula, cruciata, parvula, 
Succinea oblonga, var., and Pisidium roseum ; in those elevated regions 
many specimens of several species are whitish or pale green, instead of 
brown or dark : this the author thinks is a protective consequence of the 
cold and foggy climate. Papa arctica (Wallenberg), otherwise only 
known from Lapland, is analogous in its distribution to some species of 
Arctic plants also found in the elevated regions of the “ Riesengebirge,” 
but not in any part of the Alps. Arch. f. Nat. xl. pp. 179-259 (a part 
of it, concerning the “ Isergebirge,” also published as an inaugural thesis 
of the “ Luisenstiidtische Gewerbeschule,'’ Berlin).
