8 PEOCEEDINGS OP THE NATIONAL MUSEUM vol.80 



This species, described by d'Orbigny from the West Indian region, 

 has been found to be common in that area, and also is found in the 

 Miocene of Florida. In the present collections it occurred in con- 

 siderable numbers at station 8 but was not seen elsewhere. 



Genus LAGENA Walker and Jacob, 1798 



LAGENA ASPERA Rcoss 



Plate 3, Figtjbe 7 



Lagena aspera Cushman, U. S. Nat. Mus. Bull. 104, pt. 4, p. 8, 1923. 

 This species is rare at station 97, Port William, Falklands.

D'Orbigny's original specimens came from the Falkland Islands 

 and the coast of Patagonia. His figure shows a pyriform specimen 

 with numerous costae and with the base ending in a definite spine. 

 Our figured specimen, which is from station 8 off the South American 

 coast, resembles d' Orbigny's in the longitudinal costae and the basal 

 spine, but the shape of the test is quite different. This is the only 

 material in the collection that at all approaches this species. 



LAGENA PERLUCIDA (Montagu) 



Plate 3, Figure 6 



Lagena perlucida Cushman, U. S. Nat. Mus. Bull. 104, pt. 4, p. 46, 1923. 



This is by far the commonest species of the genus in the present 

 collections, occurring in considerable numbers at Port Stanley, Falk- 

 lands, and as scattered specimens at other stations in that region, 

 as well as stations 8 and 2 to the northward. As usual there is con- 

 siderable variation in the shape and costae in this species. 



LAGENA LYELLI (Segwenza) 

 Plate 3, Figure 8 



Lagena lyelli Cushman, U. S. Nat. Mus. Bull. 104, pt. 4, p. 34, 1923. 



At station 8 there are numerous specimens of the form here figured 

 that may be referred to Seguenza's species. There is a slight basal
