MOLLUSCS OF THE GREAT B.VSIN 



This area is of great interest on ac- 

 count of its desert conditions and the 

 Quaternary history of its great lakes, 

 Lahontan, of which Great Salt Lake 

 and Sevier Lake are the descendants, 

 and Humboldt, Walker, Pyramid, Car- 

 son, and other small lakes wliich are 

 relics of the great glacial Lake Bon- 

 neville. The molluscan fauna of these 

 relic lakes is in some respects peculiar.

 and Recent Mollusca of tiie Great 

 Basin, in Bull. 11, U. S. Geol. Surv.
