adherent tufts of hair resembling tubercles. "When this covering is 

 removed the surface of the carapace is smooth and polialied, with the 

 gastric region and its four post-frontal tubercles distinct. 



The leugth of the carapace is considerably less than its breadth 

 between the antero-latetal angles. 



Front a little more than half the breadth of the carapace, obliquely 

 deflexed, its free margin nearly straight. The lateral borders of the 

 carapace are nearly parallel and anteriorly are cut into three blunt 

 lobes of nearly equal size — including the outer orbital angle. 



The chelipeds when denuded have a smooth surface and sharp bor- 

 ders : they ai'e similar in the two sexes, except that they are nmch 

 more massive in the male. There is a blunt angular projection at the 

 far end of the inner border of the arm, the inner angle of the wrist is 

 pronounced but not dentiform, and the upper border of the palm is 

 traversed foi'e and aft by a fine sharp ciest : in the male the palm is at 

 least as high as long : the upper border of tlie dactylus is faintly 

 crenulate in its proximal two-thirds. 



The meropodites of the legs are foliaceons, but their breadth is less 

 than half their length : their borders are entire. The dactyli of the 

 legs are claw-like, their length being about three-fourths that of the 

 propodites. 



The abdomen of the male is narrow. 



In the Indian Museum are 4 specimens from Bombay and Karachi : 

 the carapace of the largest is 8| millim. long and 10 milliin. broad.

Carapace deep, nearly flat dorsally, square, its length being slightly 

 less than its breadth between the antero-lateral angles. All tlie n.-gions 

 ai'e quite well defined, and the 4 post-frontal tubercles — the middle two 

 of which are not very much broader than the outer ones — are veiy pro- 

 minent. The whole dorsum of the carajmce is coveicd with tufts of 

 hair, which are largest and longest anterioi'ly. There are some oblique 

 strife on the sides of the epibrauchial regions. 



Front half, or a little more than half, the breadth of the carapace,
