Dr. Anderson kindly compared this species for me with the 
(single) type specimen of White’s Zelphusa grapsoides preserved 
in the British Museum. Telphusa grapsoides has a more square 
cephalothorax, the length of which is nearly equal to the distance 
between the epibranchial teeth, and the front is more prolonged 
forwards. The anterior or internal (median) portion of the post- 
frontal ridge is very feebly, if at all, marked in White’s species, 
but the posterior or external portion presents the same form and 
direction in both species. 
The dimensions of the type specimen of White’s Z. grapsoides 
are as follows :—

Telphusa grapsoides, which I have never seen, inhabits the 
Philippine Islands. 
Telphusa levis, Wood-Mason, from Central India, is also more 
or less similar to this species, but differs from it in its more 
enlarged cephalothorax, the different form of the abdomen of the 
male, &e.

The Collection contains a third species of the genus Telphusa, 
a single male specimen of which was coilected in Elphinstone 
island Bay.
