than the s])ire ; labium two-tootlicd ; lower tooth small ; labrum without 

 teeth. Length one fit'ili of an ineii. Inhabits Rhode Island.

 smallest species I have seen, and was presented to me by Dr. (iriliith. 

 (Say). 



Mklampus Borealis. Shell ovate-acute, elongated ; pale horn- 

 color, with darker longitudinal bands; whorls G or 7, with a revolving 

 impressed line below the suture ; spire elevated, conical ; columella 

 with three distant and distinct plaits, the middle one most prominent ; 

 aperture obovate-acute. Length, about one fourth of an inch. 



This small species of Melimpus has been found sparingly on the coast 

 of Rhode Island, by Lieut. Brown of Newport. It is similar in form to a 

 BuUmus, and is very unlike the common species with which it associates. 

 (Conrad). 



Genus BLAUNERIA Shuttleworth. 



Shell imperforate, oblongly turreted, thin ; aperture narrow, elon- 

 gated ; parietal wall with one fold near the columella, which is subtruu- 

 catcd ; peristome simple, not reflected. (Pfr.) 



This genus was proposed for the following species. Its 

 habits and the characteristics of the animal remove it from 

 Achatina and Oleacina, where it was formerly placed.
