QUINQUELOCULINA LAEVIGATA d'Orbigny 



Plate 1, Figures 5, 6 



QuinquelocuUna laevigata Cushman, U. S. Nat. Mus. Bull. 104, pt. 6, p. 30, 1929. 

 There are numerous specimens from the stations along the Brazil- 

 ian coast that are referable to this species, which is a typically West 

 Indian one. 



QUINQUELOCULINA COSTATA d'Orblgny 



Plate 1, Figures 8 (i-c 



QuinquelocuUna costata Cushman, U. S. Nat. Mus. Bull. 104, pt. 6, p. 31, 1929. 

 As might be expected, this species, which is a common West Indian 

 one, occurs only in our material from Rio de Janeiro Harbor, and 

 there it is rather rare. 



Genus TRILOCULINA d'Orbigny, 1826 



TRILOCULINA CIRCULARIS Bornemann 



Plate 1, Figures 12 a-c 



TrilocuUna circularis Cushman, U. S. Nat. Mus. Bull. 104, pt. 6, p. 58, 1929. 



This species, which is very widely distributed, occurs in consider- 

 able numbers at the stations off the Falklands and northward along 

 the coast of Rio de Janeiro Harbor. 



Genus PYRGO Defrance, 1824 



PYRGO SUBSPHAERICA (d'Orbigny) 



Plate 1, Figures 13 a, 6 



Pyrgo sulsphaerica Cushman, U. S. Nat. Mus. Bull. 104, pt. 6, p. 68, 1929. 



This species, which is so abundant in shallow water in the West 

 Indian region, appears to be very rare along the coast of South 

 America. There are specimens from Rio de Janeiro Harbor, which 

 may possibly be assigned to it, and also from station 8. 



Family OPHTHALMIDIIDAE 

 Genus CORNUSPIRA Schultze, 1854 



CORNUSPIRA INVOLVENS Reuss 

 Plate 2, Figure 1 



Cornuspira involvens Cushman, U. S. Nat. Mus. Bull. 104, pt. 6, p. 80, 1929. 



A large proportion of our stations have this species present in few 

 numbers. The only one at which it could be considered common is 

 station 105, Port William, Falklands.
