66 FLUMINICOLA. 
3. FLUMINICOLA FUSCA, Haldeman. 
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 subglobosus, Say.
