142 A. Alcock — Carcinological Fauna of India. [Na. 3v 



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 t& 

 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 

 4th 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.
