GEOGRAPHICAL DISTRIBUTION. 
121 
73 species of land and fresh^water shells found near Hohenwittlingen, 
Wurtemherg^ on jurassic soil, are enumerated by D. Weinland, Nachr. 
mal. Ges. 1874, pp. 41-46. 
The malacological fauna of tlie lakes in Ujiper Banaria has been 
examined by S. Ci-essin ; many of them have somewhat peculiar forms, 
possibly transformations of other well known species by local influence, 
but others must at present be classifled as peculiar species. The author 
distinguishes — 1, high lakes or tarns (Hochseen), situated at a consider- 
able height in the mountains, of small size, and very poor in Mollusks, for 
example, the Schliersee and Tegernsee ; 2, larger lakes, surrounded by high 
precipitous rocks and of considerable depth, with a moderate number of 
Mollusks, for example, the Konigsee, near Berchtesgadcn ; 3, large lakes 
with flat banks, traversed by rivers and very rich in Mollusks, many of 
peculiar forms ; for example, the Ammersee and Starnbergersee. The 
number of species found in each lake is stated. CB. Ver. Regensb.

Southern Bavaria. S. Clessin adds to the fauna: — Limax variegatus, 
Tfgalina draparnahU^ Helix ruhigmosa, cailata, thjmorum, Clausilia 
nigricans., Pupa striata, Amphipeplea glutinosa, Valvata alpestris, and 
Bythinella cylindrica. Nachr. mal. Ges. 1874, pp. 19-23. 
19 species of Mollusks living in the peat-moors of this district are 
also discussed by S. Clessin ; many of them form peculiar varieties, dis- 
tinguished by dwarf size and thin shell ; Limncea stagnalis occurs there 
only in specimens with rather short spire ; no Anodonta has been found. 
But in a moor (Lindenried,.near Essendorf, Wurtemberg) traversed by 
clear water-springs which make their way from the ground through the 
peat, several other species and varieties have been found, viz., Valvata 
piscinalis, Limncea palustris, var. corvus, L. stagnalis, with elongate spire, 
and Anodonta rostrata. These are also found in a fossil state in the 
undermost alluvial layer of the normal peat-moors ; they have been evi- 
dently extinguished by the deterioration of the water. JH. Ver. Wiirtt.

Switzerland. Additions to the malacological fauna of the canton 
of the Grisons, by A. Stein, JB. Ges. Graub. (2) xvii. pp. 133-139. 
30 species are mentioned, and albino varieties of several of them ob- 
served. 
P. Godet has examined the species of Anodonta living in the lake of 
NeufchatelandMorat (Murten); Bull. Soc. Neufeh. ix. pp. 145-151 (1871). 
Fauna of Caves.

F. A. Forel has published new and interesting observations on the 
fauna of the depths of the lake of Geneva, in which living specimens of
