A. Alcock— Carcinological Fauna of India. 
Of 24 specimens from different parts of India tliere is not one of 
great size, nor a single adult female. 
I believe that this species is only the young form of Doclea hybrida.

This species differs from Doclea muricata, only in the following 
characters, which, I think, are merely due to age : — 
(1) it is much larger ; 
(2) the spine of the antero-lateral series is (except in small females) 
the smallest, and tubercles are found instead of spines on the dorsal 
surface of the carapace, the tubercles corresponding in number and 
position with the spines of D. muricata ; 
(3) the clielipeds in the adult male are nearly as long as the 
carapace and rostrum, and have the hands enlarged. 
As in D. muricata the female abdomen consists of four segments. 
As Fabricius, loc. cit., says of this species compared with D. muricata, 
vix distinctus videtur. 
We have 29 good specimens from different parts of India, all 
being large males and eg’g-laden females. I think that they can only 
be the adult stage of Doclea muricata.

Body and legs, except the hands and dactyli, covered with a dense 
stiff fur, so stiff on the trunk'legs as to give their joints, though cylin¬ 
drical, a sharply quadrangular or triangular sectional form. 
The circular form of the carapace is a good deal obscured by the 
unusual development of the rostrum and of the lateral-epibranchial 
and postero-median spines. 
The rostrum is from one-fourth to two-fifths the length of the 
carapace proper, and ends in two widely divaricated spinules. 
In addition to the tooth formed by the basal antennal joint, and
