owing to the very broad depressions which somewhat vaguely delimit 

 and to a certain extent subdivide the regions. Pterygostomian region 

 more or less hairy. 



The antero-lateral borders are very indistinctly 4-lobed, the first 

 lobe being almost obsolete, the second being usually marked by a 

 granular denticle, and the third and fourth by two coarse granular 

 spines. The postero-lateral borders, which are little convergent, are 

 slightly longer than the chord of the antero-lateral. The posterior 

 border is about half the greatest width of the carapace. 



Front really bilobed. but with both the inner and the outer angles 

 of each lobe so equally prominent as to appear 4-dentate. 



Chelipeds unequal : exposed surfaces of arm either smooth, or more 

 or less scabrous, both borders of arm uneven and hairy, the distal end 

 of the upper border with two strong teeth : both the inner and the 

 outer angles of the wrist well pronounced, or even spiniform ; the 

 exposed surfaces of the wrist may be almost smooth, but are usually 

 studded, to a variable extent, with sharp little tubercles ; the upper 

 outer and lower surfaces of the hand may be almost smooth, but are 

 usually studded, in the proximal third to three-quarters, with similar 

 tubercles, in more or less distinct lines : fingers long, sharp-pointed, 

 the apposed edges with strong molariform teeth. 



Legs long, stoutish ; upper border of the meropodites scabrous and 

 spinulate, upper border of last 3 joints, and lower border of last 2, plumose. 



Colours in spirit, leaden white or yellowish. 



In the Indian Museum are 3 specimens from the Vizagapatam 

 coast and 1 from Tennasserim, ^besides one from Hongkong) : the 

 amount of granulation of the borders of the carapace and of the cheli- 

 peds is different in all.

Carapace convex fore and aft, slightly convex or flat from side to 

 side, usually broad, the regions well demarcated by deep grooves, and 

 again subdivided into lobules, which are usually convex and granular. 

 Antero-lateral borders usually four-lobed, but the lobes are shallow and 

 often indistinct. Postero-lateral borders usually concave, always short, 

 not strongly convergent.
