FOSSIL FORAMINIFERA FROM THE WEST INDIES. 35 



Gaudryina triangularis Cushman.

A single specimen from station 3461, marl, from gorge of Yumurf 

 River, Matanzas, Cuba, collected by T. W. Vaughan, is very similar 

 to this species described from the Pacific. It was found as a fossil in 

 the lower part of the Culebra formation in the Panama Canal Zone. 



Bulimina ovata d'Orbigny.

A single specimen from Bluff 2, Cercado de Mao, which is rather 

 too elongate for this species, but in the absence of more material it is 

 referred here questionably. Under this name Jones and Parker record 

 a single specimen from the Bowden marl measuring 2 mm. in length. 

 I have not been able to find it in the Bowden material I have examined. 



Virgulina punctata d'Orbigny. 



Virgulina punctata d'Orbigny, in De la Sagra, Hist. Fis. Pol. Nat. Cuba, " Foraminiferes," p. 

 139, plate 1, figs. 35, 36, 1839. 



This species, described by d'Orbigny in the Cuba monograph, has 

 been referred to but once since. Specimens in the material from 

 station 3461, marl from the gorge of the Yumuri River, Matanzas, 

 Cuba, collected by T. W. Vaughan, in their outline and form of the 

 chambers are almost identical with the figure given by d'Orbigny.

 Challenger, Zoology, vol. 9, p. 430, plate 54, figs. 17 a to c, 1884; Cushman, U. S. 

 Nat. Mus., Bull. 71, part 2, p. 98, figs. 152 a to c, 1911. 



A specimen that has an aperture like that of this species, but with the 

 whole test somewhat more compressed, was found in the material 

 from station 3461, marl from gorge of Yumuri River, Matanzas, Cuba, 

 collected by T. W. Vaughan. This species is practically unknown in 

 the fossil state.

The following is a description of this species : 



Test elongate, slender, somewhat tapering to the almost pointed initial end, 

 straight or more often somewhat arcuate, chambers numerous, little inflated, 

 sutures between the chambers of clear shell material appearing darker than 

 the main, more opaque chamber walls; surface with a few longitudinal costae,
