DESCRIPTION. 



Shell remarkably pyriform. perfectly unarmed, longi- 

 tudinally lincated with irregular, dilated, dark ferruginous 

 lines on a yellowish or white ground, interrupted or ob- 

 solete in the middle by a paler revolving band, more obvi- 

 ous in the young shell ; very numerous revolving, slight- 

 ly elevated lines, alternately somewhat larger, towards the 

 base of the shell somewhat larger, more distant and obvi- 

 ously undulated : qnre very much depressed : whorls 

 above flattened, shoulder acute, unarmed, becoming more 

 or less obtuse and even rounded in the old shell : suture 

 profoundly canaliculated : lahrum gradually contracting 

 to the canal, which is rather long. 



OBSERVATIONS. 



In its general form, this species certainly resembles the 

 true PyruLc more accurately than either of the other spe-- 

 cies of our coast, but the groove on the labium readily distin- 

 guishes it. I formerly mistook the young shells for those 

 of F. canaliciilata, Linn., which they very much resemble 

 in form, in the grooved suture and in the spiral stria^ ; but 

 they differ from them in having a much less elevated spire,
