Indian Deep. sea Crustacea. 9 



sliort, stiff, club-shaped hairs ; the regions well-defined, 

 rather tumid, much subdivided into tumid lobules, of which 

 the convexities are capped by clusters of large conical granules, 

 and the general surface also is studded, especially in the 

 young, with similar granules. 



Front narrow, horizontal, prominent, deeply cleft into three 

 prongs of nearly equal size. 



Antero-lateral borders half as long again as the postero- 

 lateral, armed with three stout pinnulate spines, not including 

 the outer orbital angle; postero-lateral borders entire, poste- 

 rior border finely beaded. 



Upper orbital wall deeply cleft into three pinnulate teeth, 

 lower orbital border deeply concave, its inner angle strongly 

 spiniform. Eye-stalks slender, rather long ; the eyes, which 

 are more ventral than terminal, are dull and faintly pigmented 

 (as in many species of Munidopsis) , and are non-faceted. 



Antennary flagella short, extremely slender, not hairy. 



Clielipeds remarkably unequal in the male, equal in the 

 female. 



The smaller cheliped of the male and both chelipeds of the 

 female are about as long as the carapace and are coated almost 

 to the finger-tips with stiflf club-shaped hairs, which are short 

 except along the upper border of the wrist and hand and of 

 the basal part of the finger, where tliey are long; beneath 

 the hairs are some scattered granules, and along the upper 

 border of the arm, wrist, and hand are some denticles; the 

 inner angle of the wrist is strongly spiniform, and the far end 

 of the upper border of the hand is dentiform. 



The larger cheliped of the male is about twice the length 

 of the carapace, about half its length being formed by the 

 hand and fingers j the greatest breadth of the hand is about 

 half the length of the carapace. It is almost smooth, the 

 upper border of the arm and hand and the inner border and 

 upper and outer surfaces of the wrist alone being furnished 

 with denticles and hairs ; the inner angle of the wrist is spini- 

 form. 



The legs are covered with short, stiflf, club-shaped hairs, 

 which are rather more thick-set on the anterior borders and 

 on the dactyli than elsewhere. The second and third pair, 

 which are rather longer than tiie first and last pair, are some- 

 what less than 1| times the length of the carapace. All the 

 dactyli end in a little claw. 



The abdomen of the male consists of seven distinct seg- 

 ments, but the third, fourth, and fifth move together. 



In life the animal is covered with a coat of mud held 

 together by the hairs above described, the only bare parts
