Test elongate, about two and one-half times as long as wide, aper- 

 tural end slightly produced, basal end rounded; chambers definite, 

 triangular in section, the periphery bluntly or even acutely angled, 

 the sides slightly channeled; sutures not definitely depressed; wall 

 smooth; aperture rounded, with a slight neck and simple tooth. 



This species was originally described from the Gulf of Marseilles 

 by Schlumberger. It is recorded by Martinotti from Tripoli; from 

 Corsica by Heron- Allen and Earland; from the Island of Delos and 

 the Bay of Palermo by Sidebottom. Prom about the British Isles 

 it is recorded by Heron-Allen and Earland from the Clare Island region 

 of Ireland and from off the coast of Scotland. I have not found 

 the species in the western Atlantic. 



The specimens figured by Heron-Allen and Earland and reproduced 

 here are not very close to Schlumberger 's figured specimens.

Quinqueloculina polygona d'Orbigny, in De la Sagra, Hist. Fis. Pol. Nat. 

 Cuba, 1839, "Foraminiferes," p. 198, pi. 12, figs. 21-23.— Cushman, Proc 

 U. S. Nat. Mas., vol. 59, 1921, p. 66, pi. 16, figs. 3, 4; Publ. 311, Carnegie 

 Instit. Washington, 1922, p. 68; Publ. 344, 1926, p. 82. 



Test somewhat longer than broad; chambers distinct; sutures 

 slightly depressed; each chamber polygonal in cross-section, the peri- 

 phery usually concave, with a projecting carina at either angle; aper- 

 tural end extending into a short, cylindrical neck, aperture circular 

 with an everted lip, and a single bifid tooth; surface usually dull. 



Length, 0.75 mm.; breadth, 0.25 mm.; thickness, 0.15 mm. 



This is a well characterized and widely distributed species of the 

 West Indian region, described by d'Orbigny from Jamaica and Cuba. 

 Q. polygona was placed by Brady as a synonym of Q. ferussacii 

 d'Orbigny but that is a very different species as may be seen by a 

 study of the originals.
