Station 16. Lat. 6° 59' S., long. 115° 24.7 E. Bay of Kanka- 

 maraan, S. coast of Kangeang. Reef. 



A species related to Call. pachydactyla A. M.-Edw. from the 

 Cape Verde Islands, except perhaps as regards the larger cheli- 

 pede, that is wantiug in the only male tbat was coUected. 



Carapace oue fourth of the whole length. Median rostral tootb 

 broadly triaugular, very short, subaeute ; lateral teeth, between 

 the eyeplates and the antennal peduncles, still shorter, uarrow- 

 triaugular, obtuse. Abdomen depressed, the somites of subequal 

 length, the 4th a little shorter and the 6th a little longer than 

 the rest. Caudal fan similar to that of Call. mauritiana Miers, 

 but the telson, in proportion to its length, a little less broad, 

 rounded posteriorly and very slightly concave in the middle line; 

 endopodite a little broader than long and resembling that of Call. 

 pachydactyla, but the rib in the middle is distinct. 



Eyeplates as long as Ist joint of antennular peduncle, a little 

 longer than broad at their base, triangular, anterior extremity 

 rounded, outer margin oblique ; eye dark black, small, situated 

 on the outer margin, midway between the tip and the pro- 

 ximal end. 



Internal antennae as long as the carapace, Ist and 2nd joint 

 of the peduncle of equal length, 3rd once and a half as long as 

 the 2nd; peduncle half as long as the longer flagellum. 



External maxillipedes closely resembling those of Call. pachy- 

 dactyla. 



Joints of the smaller chelipede unarmed; merus oval, once and 

 a half as long as broad. Carpus a little shorter than the merus 

 and than the palm, almost as broad as long; palm a little nar- 

 rowing distally, as long as the immobile finger. Fingers hairy, 

 not toothed. In Call. mauritiana the carpus of the smaller cheli- 

 pede is considerably longer than the palm and much longer than 

 broad. Other legs as in Call. pachydactyla. 



Abdominal appendages of the Ist somite uniramous, slender,
