A very few specimens from the Falklands have a peculiar curved 

 thickness resembling very much the species described under this 

 specific name from the North Atlantic. The shape, however, is not 

 exactly the same, and it may be found not to be this species when 

 further material is available. 



ENTOSOLENIA sp.(?) 



Plate 3, Figure IS 



A figure is given showing tlie peculiar small species with an internal 

 tube, whicli lias a very broad aperture with a decided short neck 

 and phialine lip. It is figured here for future reference. 



Genus VIRGULINA d'Orbigny, 1826 



VIRGULINA PUNCTATA d'Orbigmy 



VirguUna punctata Cushman, U. S. Nat. Mus. BuU. 10-i, pt. 3, p. 117, 1922. 



Very rare specimens, which are identical with this species so com- 

 mon in the general West Indian region, occur at all three of the sta- 

 tions in Rio de Janeiro Harbor. 



There are single specimens from three stations off the Falklands 

 which represent species belonging to this genus, but they are evidently 

 the young stages, and therefore are not specifically determinable. 



Genus BOLIVINA d'Orbigny, 18.39 



BOLIVINA PULCHELLA (d'Orbigny) 



Plate 3, Figuee 20 



Bolivina pulchella Cushman, U. S. Nat. Mus. Bull. 104, pt. 3, p. 41, 1922. 



There are a few very typical specimens of this species from two of 

 the stations in Rio de Janeiro Harbor. This is, however, a typically 

 West Indian species confined to this region of the w^estern Atlantic.
