66 FLUMINICOLA. 



3. FLUMINICOLA FUSCA, HaUeman. 

 Plate 17, fig. 19. 



Globose, smooth, whorls five, rapidly in- 

 creasing, sutures very deeply impressed; aper- 

 ture large, broadly ovate, columella thickened. 

 Color horn to light greenish. 



Alt. 10, diam. 8-6 mill. 



Oregon, California, Utah, Wyoming and 

 Dakota Territories. 



The reddish color mentioned in Haldeman's 

 original description I have not detected in any 

 specimens that have come under my notice, 

 and I suppose that it was due to a deposit of 

 iron. It is very closely allied in general ap- 

 pearance to Somatogyrus suhglohosus, Say.
