slightly convex, with an indistinct minute furrow below 

 the suture ; columella twisted, with a single fold ; canal 

 short, oblique ; mouth subovate. 

 Length .3, Breadth 3-20ths, of an inch. 



Observations. Of this little species I have received but 

 a single individual. It is more elongate than that last 

 described, and, though much like it, is specifically distinct. 

 The three last described differ so much in general cha- 

 racter from the type of the genus, that I have not without 

 much hesitation placed them here. The genus Pyrula 

 seems to have equal claims for them, and the example of 

 Lamarck, followed by Sowerby, alone made me conclude 

 to do so. The Fusus jkulneus of these authors is one of 

 this group. Like it the minor has a fold on the columella, 

 which has not deterred Lamarck from placing theficulneus 

 among the Fusi, although he says in his generic descrip- 

 tion, " columella fcevis."

* It is with peculiar gratification I place the name of my friend Judge 

 Tait, to whose kindness I am so greatly indebted, to this fine species.
