FORAMINIFERA OF THE ATLANTIC OCEAN 85 



d'Orbigny's original specimens were from Martinique. It is very 

 abundant on the north coast of Jamaica, and about the Florida Keys^ 

 and is widely distributed in the general West Indian region. Pacific 

 and Mediterranean material seems to be identical with d'Orbigny's 

 species, but the following may be distinguished, and is probably 

 specifically distinct. 



CYMBALOPORETTA BRADYI (Cushman)

Cymbalopora poeyi (d'Orbigny), var. bradyi Cushman, Bull. 71, U. S. Nat. 

 Mus., pt. 5, 1915, p. 25, pi. 10, fig. 2; pi. 14, fig. 2; Bull. 100, vol. 4, 1921,

Cymbalopora bradyi Cushman, Publ. 342, Carnegie Instit., Washington, 1924,. 

 p. 34, pi. 10, figs. 2-4. 



Test with the chambers in a very flattened, irregular spire, nu- 

 merous, as many as 10 or more in the last-formed whorl on the 

 ventral side being visible; sutures distinct and slightly depressed; 

 wall rather coarsely perforate. 



Diameter up to 0.90 mm. 



Brady, Parker, and Jones figure this form from the Abrohlos Bank 

 off Brazil. It seems to be much more common in the Indo-Pacific 

 than in the Atlantic.

Genoholotype. — Cymbalopora tabellaeformis H. B. Brady. 



Test compressed, the early chambers trochoid, later ones in annular 

 series, those of each series somewhat alternating; wall calcareous, 

 coarsely perforate; apertures in the adult consisting of a vertical 

 series of small circular openings on the sides of the peripheral face of 

 each chamber. 



Late Tertiary and Recent. Living only in the Indo-Pacific.
