The description and figure by M. Recluz, accurately repre- 

 sent a small specimen of our shells, except that the very minute 

 crowded spiral striaa are not mentioned. The outline is too 

 regularly rounded to correspond well with the description of 

 N. Panamdensts RecL Our largest specimen is 1.75 inch long, 

 and 1.4 inch wide. 



Station,— JJnkaovfiL 



Habitat. — Eealejos : Eecluz. 



Panama ; 0. B. A. I 

 "We collected 40 specimens, all of which were occupied by 

 hermit crabs. 



301. IVatica . Sp. indet. a. 



Station. — In wet sand, from half tide to low water mark. 

 The tracks of this species were abundant on the beach, and led 

 to the discovery of numerous living specimens. 



Habitat. — Panama ; 0. B. A. 1 



We collected 200 specimens, mostly on the beach one mile 

 west of the city. 



302. IVatica . Sp. indet. 6. 



Two specimens of this species were sent to me by M. Petit as 

 N. cora Orb. But the figures of that species in Orbigny's Voy. 

 Amer. Merid. and in Kiist. Oonch. Cab. represent a very 

 different shell with the form (extraordinary in this genus) of a 

 compressed cylinder ; but our shells and M. Petit's have a well 

 curved outline. It is a white and very solid but small species 

 of the mammiUate group.
