FOSSIL FORAMINIFERA FROM THE WEST INDIES. 63 



In diameter and general shape L. subraulinii suggests L. raulinii 

 Lemoine and R. Douville from Saint-Geours-en-Maremmes, Landes, 

 France, and Columbres, Province of Santander in Spain, but it differs 

 in that it has very definite pillars and a papillose surface at the center. 

 The age of the European material of L. raulinii is not definitely given. 



Lepidocyclina perundosa, new species. 

 (Plate 11, Figure 8.) 



The following is a description of this species: 



Test very much curved in two directions, so that at points 180 from one 

 another the two planes of each set are nearly parallel to one another and nearly 

 at right angles to those of the other set, strongly "saddle-shaped," surface 

 smooth when well preserved, but usually somewhat cancellate, due to erosion. 



Vertical section difficult to obtain on account of the very much doubly 

 curved shape of the test, but shows no pillars; the lateral chambers about 

 three times as long as high; central chamber large; equatorial chambers 

 increasing gradually in size toward the periphery, their height and breadth 

 about equal. 



Horizontal section, which from the shape of the test can be at best only 

 fragmentary, shows equatorial chambers roughly triangular, with the outer 

 surface convexly curved. 



Diameter 8 to 12 mm. 



Type specimen, section (U. S. N. M. No. 328194) from station 3478, 

 Nuevitas, Cuba, collected by A. C. Spencer. 



This is a very sella3form species about one-half the size of L. undosa 

 Cushman from Antigua. 



Lepidocyclina antillea, new species. 

 (Plate 3, Figure 3.) 



The following is a description of this species : 



Test compressed, circular, rather evenly biconvex, lenticular, central portion 

 highest, thence gradually thinning toward the periphery, central area strongly 

 papillate, remainder of surface less strongly so. 



Vertical section shows equatorial chambers gradually increasing in height 

 toward the periphery, those of the central region measuring less than 0.1 mm., 

 those of the periphery as much as 0.5 mm. in height; outer wall of the equa- 

 torial chambers very squarely truncated. 



Lateral chambers not numerous in the central thickened region, with only 

 6 or 7 chambers in a column, and this number is gradually reduced toward 

 the periphery. Central region and the whole test in lesser degree marked by 

 very heavy and numerous pillars, greatest width near the outer end, thence 

 gradually tapering toward the center, outer ends rounded, forming the 

 papillae of the surface. In the central region the surface area occupied by the 

 pillars is greater than that taken up by the lateral chambers. 



In the horizontal section, or at least in the somewhat broadly oblique sec- 

 tion, the equatorial chambers are of the curved Lepidocyclina form instead 

 of the more typical hexagonal shape. 



Diameter of the test averages about 5 mm.
