This species a good deal resemble?, not the Bulla turrita Moll., 

 but Sowerby's figure of that species in Thesaurus, pt. 2, pi. cxxi, 

 fig. 28. In perfectly fresh specimens the spiral furrows, which I 

 have described as very faint, may be distinct; but in the ten Chal- 

 lenger specimens they are only traceable with certainty near the 

 edge of the labial pad. Utrieulus canaliculatus (Say), is a much 

 smaller and stumpierform, much broader above with a minute apex 

 turned over on its side. ( Wats.').
