PALUDOMUS. 45 



" This is an ally of P. stephanua, Benson, so far as form is feon- 

 cerned, but it difJers widely in scidpture, and although that is not 

 a character of much iuiportance in the genus Palmlomus and its 

 allies, still, as no intermediate forms between the two are known, 

 it appears quite justiiiable to separate them."

"Found abundantly in the stream above noted; the chief 

 variation of form consists in the whorls being more or less de-

 the spire varying considerabh* in its elevation."
