FOEAMINIFERA OF THE ATLANTIC OCEAN •2*7 



and Martinique. The species is well distributed in the general West 

 Indian region and probably like so many West Indian species is found 

 also in the Indo-Pacific. There are records for it from the British 

 Isles under the name auheriana. Brady in the Challenger Report 

 evidently confused this species with Q. cuvieriana. 



In the West Indian collections these are two forms which may 

 possibly be distinct. These both have a smooth surface but in one 

 the peripheral angle is acute and the surface smooth and polished 

 whereas in the other the peripheral angle is usually more blunt and the 

 surface dull.

Test nearly twice as long as broad; chambers distinct from one 

 another; sutures sharply marked; chambers triangular in transverse 

 section, the periphery sharply keeled; wall smooth, shiny; aperture 

 comparatively small, with a simple tooth, extending somewhat above 

 the outline of the aperture. 



Length, 0.70 mm.; breadth, 0.35 mm.; thickness, 0.25 mm. 



This species is more elongate than Q. lamarckiana, and the neck is 

 protuberant. It is now known from several localities in the West 

 Indian region.

Quinqueloculina collumnosa Cushman, Publ. 311, Carnegie Instit. Washing- 

 ton, 1922, p. 65, pi. 10, fig. 10. 



Test slightly longer than broad; chambers somewhat indistinctly 

 marked from one another, the periphery angled and projecting, the 

 last-formed chamber extending out beyond the outline of the test at 

 both ends; chambers somewhat undulate; wall smooth, dull; aper- 

 tural end much contracted, extended to form a narrow, cylindrical 

 neck with a small, rounded aperture; lip indistinct. 



Length, LIO mm.; breadth, 0.80 mm.; thickness, 0.60 mm. 



Specimens of this species have a distinctive outhne with the aper- 

 tural end much contracted into a slender cyUndrical neck. The form 

 referred by Heron-Allen and Earland to Q. cuvieriana d'Orbigny is 

 the same as this species which seems to have a West Indian and 

 Indo-Pacific distribution in shallow water.
