ward the merus; merus of ambulatory legs 

 with scarcely a trace of distal tooth; carpus 

 with anterior lobes obsolescent. The antero- 

 lateral teeth are broader, thinner, and nioro 

 acute than in sica; the areolations of the 

 carapace are more sharply marked and the 

 furrows between them almost smooth ; intes- 

 tinal region finely and evenly granulate, not 

 irregularly, as in sica. 



Measurements. — Female (station 293) 

 greatest length of carapace 7, width of same 

 9.4, length of second leg 18.7 mm. Eatio of 

 length to width varies from 1 : 1.2G to 1.34. 



Uangc. — Lesser Antilles ; 5G to 138 fathoms.

 of carapace very well marked, high, trending

 Intervening space scantily filled with small 

 inconspicuous granules and short hairs. Two 

 median frontal teeth roi\nded and separated 

 by a triangular sinus ^\ith rounded base; 

 lateral sinuses shallower, equally wide, ob- 

 lique; lateral teeth triangular, subacute. 

 Sinuses of supraorbital margin triangular, 

 the outer one rounded behind; middle tooth
