Length of the carapace about three-fifths of the gi'eatest breadth 

 at the acute claw-like atitero-lateral angles. The posterior border of 

 the dorsum of the carapace — i.e., the border corresponding with the last 

 segment of the sternum — is a good deal over half the greatest bi'eadth of 

 the carapace, so that the lateral borders of tlie dorsum of the carapace, 

 •which are distinctly defined in almost two-thirds of their extent by a 

 fine raised line, are only moderately convergent. The post-gastric and 

 cardiac regions aie the only ones that are defined, and they but faintly. 



Front, measured between the bases of the eyestalks, from a fifth to 

 a sixth, the greatest breadth of tiie carapace. 



Orbits sinuous and considerably oblique ; their upper border defined 

 by a fine raised line which is very distinctly double iu a good part of its 

 extent ; their lower border vei y elegantly and regularly seirated — tlie 

 teeth increasing in size from within outwards. In the female only there 

 is a short row of granules inside of and parallel with the lower border 

 of the orbit. 



In tie large cheliped of the adult male the greatest length of the 

 hand (including fingeis) is at least three times the length of the carapace : 

 the outer surface of the somewhat rounded arm and of the wrist and 

 hand is smooth to the naked eye, with a few small granules on the inner 

 border of the wrist: the lower border of the palm is obscurely margin- 

 ate : and on the inner surface of the palm are two salient granular 

 crests, one of these is deeply grooved and nearly vertical and becomes 

 continuous with the dentary edge of the immobile finger, the other,
