are aboat as long as the carapace, and are coated, almost to the finger- 

 tips, with stiff club-shaped hairs, which are short except along the upper 

 border of the wrist and hand and of the basal part of the finger, where 

 they are long : beneath the hairs are some scattered granules, and along 

 the upper border of the arm, wrist and hand are some denticles : the 

 inner angle of the wrist is strongly spiniform, aad the far end of the 

 upper border of the hand is dentiform. 



The larger cheliped of the male is about twice the length of the 

 carapace, about half its length being formed by the hand and fingers : 

 the greatest breadth of the hand is about half the length of the cara- 

 pace. It is almost smooth, the upper border of the arm and hand, and 

 the inner border and apper and outer surfaces of the wrist, alone being 

 furnished with denticles and hairs : the inner angle of the wrist is 

 spiniform. 



The legs are covered with short stiff club-shaped hairs which are 

 rather more thick-set on the anterior borders and on the dactyli than 

 elsewhere. The second and third pair, which are rather longer than 

 the first and last pair are somewhat less than If times the length of 

 the carapace. All the dactyli end in a little claw. 



The abdomen of the male consists of seven distinct segments, but 

 the 3rd, 4th and 5th move together. 



In life the animal is covered with a coat of mud held together by 

 the hairs above described, the only bare parts being the hand and 

 fingers and part of the arm of the larger cheliped of the male. 



The colours in life are described by Dr. A. R. Anderson, as ** white 

 with a bluish tinge, eyes with a slight reddish opalescence." In spirit 

 the bluish tinge is fainter, the eyes are a pale milky yellow-ochre, and 

 the large hand is ivory-white. 



The dimensions of the largest male are as follows : — 

 Length of carapace ... ... ... ... I8'5 millim. 



Breadth of carapace ... ... -.. ... 14*5 „ 



Combined length of hand and fingers, along lower border... 14*75 „ 

 Combined length of basal joints, arm and wrist, along 



upper border ... ... ... ... 15 ,, 



Fifteen specimens were dredged off the Travancore coast at a depth 

 of 430 fms. The bottom consisted chiefly of coral (living and dead). 



Several of the specimens were egg-laden females. The eggs are 

 comparatively few in number and are large, their diameter being about 

 1*3 millim. 



This species is very like Trachycarcinus corallinus, Faxon, which was 

 dredged by the " Albatross " off Panama and the Pacific coast of 

 Mexico, at depths of 546-695 fathoms.
