Type. — M. C. Z., 7,418. Cave near seashore, between Morro 

 Castle and Cojimar; March 10, 1912. Thomas Barbour. 



Thorax stouter than abdomen; carapace strongly arched both in 

 side and front views; median carina prominent except posteriorly 

 where it fades out gradually toward the posterior margin; the down- 

 ward slope of the anterior half is continued by the upper margin of 

 the rostrum, although the latter may be a little more horizontal; a 

 row of from 4 to 6 spines begins at the anterior third of the carina and 

 is continued on the rostrum; usually 3, sometimes 2, of these spines 

 are on the carapace proper; rostrum short, reaching to middle, or 

 nearly to middle, of second segment of antennules, acutely pointed, 

 armed below with from 2 to 4 small spines. Two slender spines 

 near anterior margin of carapace, one on the suborbital lobe, the other 

 behind the antenna. 



Eyestalks short and stout, subcorneal, terminating in large, dark 

 blue corneae. 



Antennular peduncle stout, less than half as long as carapace, 

 excluding rostrum; first segment twice as long as wide, its external 

 scale turned almost vertically; scale suboval, shorter than the seg- 

 ment itself, base thickened, outer surface concave, having a broad 

 longitudinal furrow, upper margin armed near its extremity with a 

 small spine; second segment shorter than first; third § as long as 

 second; flagella about lj times as long as body. 



Antennal peduncle reaching to the end of first segment of antennular 

 peduncle; scale extending considerably beyond antennular peduncle*
