Kobelt (Dr. W.)— Geographical Distribution of Land 

 and Freshwater Mollusca. — Die Geographische Ver- 



breitung der Binnen-mollusken. — A Reprint from 



March 4, 1876, pp. 75 to 104. 



The author in a lengthened introduction unfolds his views of 

 the subdivision of the Palaearctic Region, recognizing four parallel 

 zones, the Arctic-Boreal, the Germanic, the Alpine, and the Medi- 

 terranean. He also discusses the world-provinces generally, and 

 proceeds to give various catalogues, viz. : — Tibet 19 (of which 9 

 are European), the Polar Regions 46, the Germanic Province 221, 

 the Italian peninsula 316, Sicily 229, Malta 36, Sardinia 9, Corsica 

 100, Crete 40, Rhodes 13, Cyprus 5r,and the Crimea 42 species. 

 This paper will be indispensable (together with its predecessors) 

 to all who are working out the distribution of land and freshwater 

 mollusca.

The exceptional peculiarity of the environment of this species 



in the Bay of Eastport, U.S., seems most distinctly to have 



produced a local variation affecting the male only.
