Genus CASSIDULINOIDES Cushman, 1927 



CASSIDULINOIDES PAKKERIANA (H. B. Brady) 



Plate 4, Figures 7 a, 6 



Cassidulina parJceriana H. B. Beady, Quart. Journ. Micr. Sci., vol. 21, p. 59, 1881 ; 

 Rep. Voy. Challenger, Zoology, vol. 9, p. 432, pi. 54, figs. 11-16, 1884. 



All three of the Challenger stations from which Brady had this 

 species are " amongst the islands on the west coast of Patagonia." 

 These stations are in much deeper water than is represented b}^ our 

 material. We have very typical specimens from Port William, Falk- 

 land Islands, but comparatively rare. 



Family ANOMALINIDAE 

 Genus CIBICIDES Montfort, 1808 



CIBICmES ROBERTSONIANA (H. B. Brady) 



Cibicides robertsoniana Cushman, U. S. Nat. Mus. Bull. 104, pt. 8, pp. 121, 122, 

 1931. 

 Very rare specimens showing the typical color and form of this 

 species occurred in material from Rio de Janeiro Harbor. There are 

 other records for the species from off the coast of Brazil. It was 

 found in the Albatross dredgings from the western Atlantic, and 

 seems to be a very distinct species of that part of the world. 



CIBICmES CONCENTRICUS (Cushman) 



Cibicides concentricus Cushman, U. S. Nat. Mus. Bull. 104, pt. 8, pp. 120, 121, 

 1931. 



This is one of the species originally described from the Miocene of 

 Florida, and later has been found to be fairly common, living off the 

 Florida coast and elsewhere in the West Indian region. A few 

 typical specimens occurred at station 8 in Rio de Janeiro Harbor, 

 thus extending very much to the southward the known range of this 

 species. 



Genus DYOCIBICIDES Cushman and Valentine, 1930 



DYOCIBICIDES BISERIALIS Cushman and Valentine 



Plate 4, Figure 8 



Dyocibicides biserialis Cushman, U. S. Nat. Mus. Bull. 104, pt. 8, pp. 126, 127, 

 1931. 

 All stages from the coiled young to the biserial adult were found 

 in the material from Port William. One of these is figured. It has 

 not, however, occurred at any of the other stations as far as we have 

 noted.
