angle, obliquely truncated but not emarginated at the antero-internal angle, 

 where it articulates with the following segment. Legs of moderate length. 

 Right and left chelipeds very unequally developed in the male. Dactyli of am- 

 bulatory legs styliform, straight, slender, longer than the penidtimate segments." 



Tr achy car cinUS glauCUS, Alcock and Anderson, Plate II. fig. 2. 



Carapace irregularly pentagonal, its surface coated with short stifi 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 gra- 

 nules. 



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, posterior border finely beaded. 



Upper orbital wall deeply cleft into three pinnulate teeth, lower orbital 

 border deeply concave, its inner angle strongly spiniform. Eyestalks 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-facetted. 



Antennal fiageUa short, extremely slender, not hairy. 



Chelipeds remarkably unequal in the male, equal in the female. 



The smaller chehped 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 stiff 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 they 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 : 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 spiniform. 



The legs are covered with short stiff 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 the first and last pair, are
