but gradually increasing toward the peripheral 

 portion of the test, where the chambers become 

 about three times as high as their width, and 

 the walls, instead of being straight, are con- 

 vexly curved toward the periphery of the test; 

 lateral chambers much compressed, broad and 

 low, eight or nine in a vertical coliunn in the 

 central region, diminisliing very evenly in 

 nmnber toward the periphery, where there is 

 but a single chamber on each side of the test. 

 Pillars nmnerous, rather evenly distributed, 

 very slightly increasing in diameter toward 

 the surface, only slightly laminated, coming 

 slightly above the surface at the distal ends, 

 causing the papillate surface.

 ington Pub. 291, p. 63, pi. 11, fig. 8, 1919. 



Test very much curved in two directions, 

 so that the two planes of each set are nearly 

 paraUel 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 canceUate, 

 owing to erosion. 



A vertical section is difficult to obtain on ac- 

 count of the very much doubly curved shape of 

 the test but shows no pillars, the lateral cham- 

 bers about three times as long as high, central 

 chamber large, equatorial chambers increasing 

 gradually in size toward the periphery, height 

 and breadth of equatorial chambers about 

 equal. 



Owing to the shape of the test the horizontal 

 section is only fragmentary, but it shows 

 chambers rouglily triangular with the outer 

 surface convexly curved. 



Diameter, 8 to 12 millimeters. 



Type specimen, section (U. S. N. M. No. 

 328194) from station 3478, Nuevitas, Cuba; 

 A. C. Spencer, collector. 



This is a very seUaeform species about one- 

 half the size of L. undosa Cushman, from An- 

 tigua.

 Pub. 291, p. 65, pi. 2, fig. la, 1919. 



Test of medium size, much compressed, 

 strongly undulate or saddle-shaped, not at all 

 umbonate, thin throughout; surface sUghtly 

 granulate, otherwise smooth, where worn 

 usually netted by the walls of the chambers.
