ABT. S SOUTH AMERICAN FORAMINIPERA CUSHMAN AND PARKER / 



the dorsal side gently curved, very slightly depressed, only those of 

 the last-formed whorl distinct, on the ventral side gently curved or 

 with a sinuous, lobed condition, especially in later portions, distinct ; 

 wall finely arenaceous with much chitin, thin, very flexible when wet ;, 

 aperture ventral, along the margin of the last-formed chamber. 



The above description, which is copied from the original, applies 

 equally well to our specimens from station 2, off Ilha Paqueta, Rio 

 de Janeiro Harbor. The jDeculiar sinuous arrangement of the ventral 

 side is perhaps not quite so marked as in the types from off Peru, 

 but otherwise the specimens agree very well with the types. 



Family LAGENIDAE 

 Genus NODOSARIA Lamarck, 1812 



NODOSARIA CALOMORPHA Reuss(?)

Nodosaria calomorpha Reuss, Denkschr. k. Akad. Wiss. Wien, vol. 25, p. 129, 

 pi. 1, figs. 15-19, 1885. 



At numerous stations from station 8 southward to the Falklands 

 there occur numerous fragmentary specimens, never consisting of 

 more than three chambers, which may be referred with some question 

 to this species of Reuss. The chambers, as shown in the figured ones, 

 are somewhat longer than broad, and the sides are broadest in 

 the middle. The one with three chambers shows that it comes from 

 a specimen that had at least two other chambers, and it is probable 

 that this does not represent very closely Reuss's species from the 

 Tertiary of Europe, but it is not sufficiently complete for full descrip- 

 tion. Our specimens are exactly identical with those figured by 

 Brady in the Challenger report under this name.

Test composed of two chambers, the proloculum subglobular, with a 

 short basal spine, the second chamber more pyriform, apertural 

 end somewhat prolonged; suture distinct and depressed; wall orna- 

 mented with numerous, very distinct costae, which extend the entire 

 length of the two chambers to the aperture.
