The right cheliped is smaller, but not much shorter, than the left : the 

 upper border of the palm and dactylus is serrated, the outer surface of the 

 palm is granulous, and there is a spine at the far end of the upper border 

 of the carpus and of the outer border of the merus. 



The 2nd and 3rd legs slightly surpass the chelipeds : they are smooth, 

 except for a spine at the far end of the anterior border of the carpus ; and 

 are sparsely setose, except the posterior border of the dactylus and of the 

 distal two-thirds of the propodite of the 3rd pair, where the setae form a 

 thick brush : the dactyli look much shorter, but are really little shorter than 

 the propodites, 



Colours in spirit : chelipeds and legs rich chestnut brown, the tips of 

 the fingers — and of the dactyli behind the black claws— white ; basal two- 

 thirds of the eyestalks rich brown, distal third blue ; antennules brown and 

 yellow, antennae yellow ; anterior part of the carapace more or less speckled 

 with brown. 



Length of carapace about 10 millim. 



Distribution: Islands of the Indo-Pacific from Minnikoy and the 

 Maldives to Tahiti (Nicobars, Amboma, Balabac Str, and SuluSea, Liu Kiu 

 and Ohosima, Funafuti, Rotuma, and Fiji). 



The specimens here described are from Minnikoy and the Maldives.

Calcinus terrcB-regince, tiasweW, Proc. Linn. Soc, N. S. Wales, VI. 1881-82, p. 760; and 

 Cat. Austral. Crust. 1882, p. 158 : de Man, Arch. f. Naturges. LI 1 1. 1887, i., p. 439 ; and Journ. 

 Linn. Soc. Zool., XXI 1. 1888, p. 226. 



This is perhaps only a variety of C, latens, Kandall. 



The slender eyestalks are about half agam as long as the anterior 

 border of the carapace : the antennal acicle well overlaps the base of the 

 terminal joint of the peduncle; the flagellum is a good deal longer than the 

 carapace. 



The left cheliped is much the more massive : the upper border of the 

 merus is faintly serrulate ; there is a spinule at the far end of the upper 

 border of the carpus ; the oblique groove on the outer surface of the carpus 

 is faint, and is defined externally by a conspicuous tubercle : the palm is 

 very slightly longer than high, its lower border and that of the fixed finger 

 are granulous on the inner aspect : the fingers meet only at tip, and their 

 opposed edges are obscurely toothed. 



The right cheliped shows a large terminal spine on the upper border of 

 the wrist : the outer surface of the wrist and hand bears numerous scattered
