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 cuvieriana. The specimens have a peculiar 

 outline, very contracted apertural end, and an undulate, projecting, 

 somewhat angled aperture. 



Quinqueloculina poeyana d'Orbigny. 



Quinqu.eloculina poeyana d'Orbigny, in De la Sagra, Hist. Fis. Pol. Nat. Cuba, 1839, "For- 

 aniiniffrcs," p. 191, pi. 11, figs. 25 to 27.— Cushman, Proc. U. S. Nat. Mus., vol. 69, 

 1921, p. 67, pi. 16, fins. 7, 8. 



Test two to three times as long as broad ; chambers distinct ; sutures slightly 

 depressed ; periphery rounded ; surface ornamented by numerous longitudinal 

 costse, 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 

 costse which, instead of being uniform, are usually irregularly toothed through- 

 out, giving a peculiar roughened appearance to the test; costse 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 costse 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.
