These shells show almost invariably but three teeth — the parietal, 
columellar, and lower palatal, with the upper palatal represented if at all 
only by a very small tooth or a mere trace. No angular lamella w r as noted 
in the case of any of the specimens cleaned, in this particular differing from 
the race of V. modesta found in Glacier National park, Montana, -which 
are mainly of the parietalis type (Berry, 1919, p. 204). Similarly toothed 
shells from the two lots are quite closely alike, however. The same speci- 
mens seem already to have been recorded in print by Whiteaves (1905, 
p. 171).
