GOES: FORAMINIFERA. Ur 
Is not of rare occurrence in the Caribbean Sea; the circumvolutions and 
sutures on the spiral side are often hidden by a cupula of exogenous polished 
white shell substances. 
Caribbean Sea. 200 fathoms (Goés).

P. pauperata BR., 1884, Chall. Rep., IX. p. 696, Pl. CIV. Figs. 3-11 
This broad-winged singular form is a prominent constituent of the abyssal 
Foraminifera ground on both sides of the Isthmus. It seems to arrive ata 
higher development in the Pacific. 
Pacific. 770-1132; plenty.

Not common in the tropical seas. It cannot be specifically distinguished from 
Rotal. oblonga WILLIAMS，The broad form represented in Chall. Rep, Pl. CVL, 
under the name of P. oblonga, does not quite agree with Williamson’s form. 
Caribbean Sea. 169 fathoms; scarce.

Differs from the type of d’Orbigny in its less rounded margin and more in- 
equilateral shape, the margin being at nearly equal level with the spiral side, 
Our form has from 7 to 9 segments in the outer convolution. It is usually 
broader than the type, 
Schwager has described two other forms, P. subinflata and P. Mölleri, with no 
specific characters that distinguish them from semiplecta, 
Rot. Brongniartii D'ORB., Bass, tert. Vienne, p. 158, Pl. VIII. Figs, 22-24, 
can hardly be distinguished but by its thinner edge from P. Hauerii, and may 
be considered as a broader auricula. Our present form comes near Brady’s ob- 
longa, Chall. Rep., IX. Pl. OVI. Fig. 4, both in the number of segments and in 
the limbation of the sutures, but our form is broader, approaching to orbicular 
Rotaline, 
Pacific. 1201 fathoms, Scarce,
