It is with some hesitation that I describe these shells which Bland 

 thinks may be a variety of D. lilaceus, and Weinland refers to D. 

 stramineus; but I am satisfied that they cannot be a variety of the 

 former species, and the latter is widely separated geographically and 

 presents several differential characters. The specimens before me, 

 from the Robert Swift and A. D. Brown collections, are probably 

 none of them quite mature.

 glossy, engraved with fine spirals.

The exact |><iti<>n and stains of this form are not easily decided. 

 It si-t-ms to tie what Bland and others have referred In buliniiiriisis as 

 a \arieiy. Some lorin- of J). palpoloenrit Slreliel are \ rry similar,
