The colours in tlie fresh state are, carapace pinkish yellow, legs pink. 



This species is characteristic of depths between 60 and 100 fathoms in the 

 Bay of Bengal, and there are scores of specimens in the Indian Museum. 



Ericephaloides Rivers-Andersoni, n. sp. 



Differs from the preceding species in the following particulars : — 



(1) The carapace is more elongate and narrower, on account not only of 

 the greater relative length of the rostrum, but also of the less puffed out ptery- 

 gostomian regions. 



(2) Although the angles of the buccal cavern are strongly produced, they 

 do not reach beyond the level of the retracted eye. 



(3) The eyes are much paler. 



(4) In the (? adult) male, though not in the adult female, the rostrum is 

 much longer, its length, measured from the pre-ocular spine, being nearly half 

 that of the rest of the carapace. 



(5) In the ( ? adult) male also, though not in the female, the palm instead 

 of being cylindrical is compressed and appreciably broadened so as to be con- 

 spicuous as the stoutest joint in the whole series of legs. 



Length of carapace of male 26 milhm., breadth 21 millim. Length of 

 carapace of female 22 millim., breadth 18 mdlim. 



Ten specimens from off Travancore coast, 406 fms. 



This species closely resembles E. armstrongi, but the shape of the carapace, 

 especially of the pterygostomian regions, is quite different in both sexes ; and 

 in the male the form of the rostrum and of the hands are also quite different.

Carapace elongate sub-pentagonal, broad behind, tapering in front to a huge 

 rostrum formed of two spines (fused together to near the tip). The surface of 

 the carapace is symmetrically and deeply honey-combed by broad deep channels 

 which leave symmetrical tubercles with over-hanging edges between them. 



There are no true pre-ocular and post-ocular spines, but the eye is deeply 

 sunk between two low smooth excrescences which are pre-ocular and post-ocular 

 in position. 



The basal antenna-joint is truncate-triangular, and the antennary flagella 

 are completely hidden beneath the rostrum.
