A species of medium size, related to Call. maldivensis Borr. 

 Rostrum spiniform, reaching to the middle of Ist joint of anten- 

 nular peduncle. Carapace one third the length of the abdomen, 

 Abdomen, except the caudal fan, sirailar to that of Call. jocula- 

 trix, Ist somite saddle-shaped, 2nd and 6th of equal length, louger 

 than the rest. Telson measuring three fourths of the length of 

 the 6th somite, slightly longer than broad, hind border emar- 

 ginate with sharp median tooth eurved foreward. Both swimmerets 

 longer than the telson, inner ramus once and a half as long as 

 broad, oval, rounded apically. Exopodite not yet ouce and a half 

 as long as broad, anterior border straight, making a right angle 

 with the apical one and this angle quite distinct, not rounded; 

 additioual series of short bristles reaching not yet to the middle 

 of the apical border, contiguous to and diverging very little from it. 



Flagella of inner antennae slightly longer than the peduncle, 

 3rd joint of the peduncle 3-times as long as second. Antennal 

 peduncle longer than the antennular one. External foot-jaws 

 similar to those of Call. rotundicaudata Stebb., merus a little 

 broader than long and than the ischium, armed anteriorly with 

 a spine. 



The lower border of the ischium of the larger chelipede armed 

 with 11 spines; merus broadly oval, not yet ouce and a half as 

 long as broad, lower margin expanded, spiniferous and denticulate 

 along its whole length. Carpus short, more than ouce and a half 

 as deep as long; palm twice as long as the carpus, slightly broader 

 than it and longer than the fingers. Lobe at the hinder edge 

 of the propodite of 3rd legs obtuse, triangular, measuring one 

 sixth of the length of the whole joint; three shallow notches of 

 equal length on the lower margin, the first of them a little farther 

 distant from the proximal than from the distal extremity of the 

 margin.
