66 SHALLOW-WATER FORAMINIFERA OF TORTUGAS REGION. 
tended to form a narrow, cylindrical neck with a small, rounded aperture; 
lip indistinct. 
Length of largest specimens up to 1 mm. 
This is very close, if not identical, with the specimens figured by 
Heron-Allen and Earland from the Kerimba Archipelago and referred 
by them to d’Orbigny’s cuviertana. The specimens have a peculiar 
outline, very contracted apertural end, and an undulate, projecting, 
somewhat angled aperture. 
Quinqueloculina poeyana d’Orbigny. 
Quinqueloculina poeyana d'Orbigny, in De la Sagra, Hist. Fis. Pol. Nat. Cuba, 1839, ‘* For- 
aminiféres,’’ p. 191, pl. 11, figs. 25 to 27—-Cushman, Proc. U.S. Nat. Mus., vol. 59, 
1921, p. 67, pl. 16, figs. 7, 8. 
Test two to three times as long as broad; chambers distinct; sutures slightly 
depressed; periphery rounded; surface ornamented by numerous longitudinal 
costz, running from the base of the chamber to the apertural lip; apertural 
end slightly extended, very slightly, if at all, constricted, lip slight; aperture 
circular, with a single narrow tooth, somewhat slightly bifid at the tip. 
Length of the Tortugas specimens 0.60 mm. 
This is one of the Cuban species which Brady did not place as a 
synonym in the Challenger Report. Both in the collections from the 
north coast of Jamaica and in that from the Tortugas region it is 
fairly common, and is very constant in its characters, agreeing well 
with the figures of d’Orbigny, except for the size of the aperture, 
which is not nearly so small in our specimens as figured by d’Orbigny. 
Quinqueloculina subpoeyana, new species. 
Test elongate, about 2.5 times as long as wide; chambers distinct; the aper- 
tural end projecting a considerable distance beyond the outline of the test; 
the peripheral border rounded; surface ornamented by numerous longitudinal 
cost which, instead of being uniform, are usually irregularly toothed through- 
out, giving a peculiar roughened appearance to the test; cost continued to 
the aperture, which is very slightly contracted, with a very thin lip, with a 
single tooth; surface dull. 
Length up to 0.60 mm. 
Q. subpoeyana may be distinguished from Q. poeyana by its more 
open form, much more extended apertural end, and especially by the 
character of the surface, the uneven-toothed cost giving it a very 
unique appearance. This character is constant in the many speci- 
mens examined. It is one of the characteristic species of the collec- 
tion, occurring at most of the stations.
