22 Major A. Alcock and Capt. A. R. S. Anderson on 



large spines on the inner edge of the merus of the external 

 maxillipeds. 



Chelipeds in the female (male unknown) slender, unequal, 

 the larger one slightly longer, the smaller one very slightly 

 shorter, than the fully extended body ; two rows of spines on 

 the arm, both series continued, but much less conspicuously, 

 along the wrist, but not along the hand ; the fingers meet 

 throughout their length. 



Legs long, the first three pairs being scarcely shorter than 

 the fully extended body : their merus has a few spinules at 

 the proximal end of its anterior border, and both its borders 

 terminate acutely; their carpus is carinate and ends in a 

 spine; their dactylus is more than half the length of the pro- 

 podite and has its posterior border spinulate. 



A single female from off the Travancore coast, 430 fathoms. 



The length of the carapace is 21*5 millim., of the larger 

 cheliped 24 millim., of the smaller cheliped 21 millim. 



Munidopsis Moresbi/i, sp. n. 



Carapace convex, broader behind than in front, covered as 

 far as the tip of the rostrum with transverse, squamiform, 

 ciliated sculpture, spineless, the regions inconspicuous. 



Rostrum of moderate length, simple, triangular, dorsally 

 carinate. A blunt tooth on the anterior border of the cara- 

 pace ; lateral borders cut into two blunt lobes exclusive of 

 the subacute antero-lateral angle, but these lobes may be 

 almost indistinguishable ; posterior border smooth. 



Abdomen unarmed, the second to the fifth terga trans- 

 versely grooved ; the fifth and sixth terga, the telson and the 

 outer half of the blades of the swimmeret, and the margins of 

 the pleurae with a fine, rather irregular, squamiform sculp- 

 turing. 



Eyes freely movable, spineless, more or less retractile 

 beneath the rostrum. 



Two very inconspicuous teeth on the inner edge of the 

 merus of the external maxillipeds. 



Chelipeds and legs covered with ciliated squamiform 

 sculpturing, unarmed. 



Chelipeds moderately stout, equal in both sexes, as long as 

 the body in its natural pose (with the abdomen flexed), not 

 half a dactylus longer than the legs ; palm and fingers as 

 long as the three preceding joints combined, the fingers 

 slightly longer than the palm. 



The dactyli of the legs are about half the length of the 

 propodites and have the posterior border serrated.
