It is impossible to refer these small retusa-\ike Succineas with any 
degree of certainty to any of the described species, but without the animals 
— which writers are now generally agreed must constitute the main reliance 
in working out of the prevailing chaos in this group — it would, probably, not. 
be in the interest of science to describe them as new. The specimens 
from west of the Rockies are in poor condition; hence it is by no means 
certain that all the lots listed are referable to the same species. The west- 
ern Succineas are very poorly understood and many of them are, therefore, 
in a state of supreme confusion in the literature. They need competent 
revision badly. All the present specimens were labelled “ Succinea ovalis 
Gould” by Dr. Whiteaves.
