FOSSIL FORAMINIFERA FROM THE WEST INDIES. 



Lepidocyclina canellei Lemoine and Douville var. yurnagunensis, new variety. 



(Plate 12, Figures 7, 8.) 



57 



The following is a description of this variety : 



Test differing from the typical form of the species mainly in the form of the 

 lateral chambers, which are somewhat broader, and with the upper wall 

 decidedly arched; embryonic chambers either two, subequal or very unequal, 

 or several, the equatorial chambers hexagonal or obscurely diamond-shaped. 



Type material from U. S. G. S. station 7348, from flexure 2 miles 

 south of Yurnaguna, Cuba, collected by O. E. Meinzer. 



At this station the material is largely composed of this species, as the 

 section (plate 12, fig. 8) shows. None of these sections happens to 

 be exactly vertical. The variety shows the embryonic characters of 

 all three of Douville's subgenera : equal chambers, as in the type from 

 Panama (Isolepidina) ; unequal, one small, the other partially encircling 

 and kidney-shaped (Nephrolepidina) ; and with two irregular large 

 embryonic chambers and two or more small ones (Pliolepidina) . The 

 latter condition is shown in plate 12, figure 7. 



In gross appearance, color, and general characters this material 

 very strikingly resembles that from Bohio, Panama, the type locality 

 for L. canellei.

 Mem. 32, p. 14, plate 1, fig. 10; plate 2, fig. 6; 1904. 



The following is a description of this species: 



Test large, compressed, lenticular, thickest in the central region, from which 

 it gradually thins out toward the periphery, somewhat flexuous and slightly 

 saddle-shaped; surface fairly smooth or somewhat finely granular, the granules
