142 Carcinological Fauna of India. 
Carapace broader than long, convex, smooth, without distinction of 
regions: the cervical groove broad, shallow. 
Front cut into 3 broad triangular teeth of about equal size, the 
middle one of which is on a lower plane than the others and is deflexed. 
A sharp tooth near the middle of the upper border of the orbit 
marks the true inner supra-orbital angle. Outer orbital angle denti- 
form. Suborbital lobe dentiform and very prominent. 
True antero-lateral border cut into 3 or 4 blunt teeth: in the gap 
between the 1st tooth and the outer orbital angle two subhepatic 
teeth—one of which is large—show up and, from a dorsal view, look 
as if they belonged to the antero-lateral border: there are two similar 
teeth, one alone of which is conspicuous, at the outer angle of the buccal 
cavern. 
On the postero-lateral border, at the branchial or “ cervical’’ 
groove, is a denticle. 
Wrist and palm, and corresponding joints of first two pair of legs, 
sharply and profusely nodular or tubercular on the outer surface : 
fingers compressed. 
The third pair of legs, though much slenderer and less nodular than 
the first two pair and only about half their length, are fashioned on 
much the same plan, except that the propodite is much shortened : the 
spinule at the end of the propodite of this pair is not big enough to 
form a chela with the claw-like dactylus. 
Last (4th) pair of legs slender and smooth, hardly a dactylus 
length shorter than the 2nd pair: their propodite has spines at the end 
of both borders, the spine at the end of the anterior border being large 
enough to form a chela with the dactylus. 
Abdomen of the male slightly convex along the middle line, the 
Ath and 5th terga with some little nodules: in the female the 3rd—5th 
terga have the surface a little uneven, but not distinctly nodular. 
Every specimen has a commensal sponge which covers it com- 
pletely like a cap. 
In the Indian Museum are 70 specimens from the Andaman reefs. 
The carapace of a large egg-laden female is 9 millim. long and 
11 millim, broad.
