Indian Deep-sea Crustacea. 21 



the legs : the larger is about half as long again as the fully 

 extended body and from a dactylus to half a dactylus longer 

 than its fellow, and has the hand enlarged and the immovable 

 finger so arched that the fingers meet only at tip; the 

 smaller cheliped is very variable, sometimes it is hardly 

 different from its fellow, but usually it is more slender, 

 especially in respect of the hand, and usually the fingers meet 

 throughout the greater part of their extent. 



In the female the chelipeds are stouter, but not vastly 

 stouter, than the legs, and are about as long as the fully 

 extended body, and the fingers are nearly straight. 



The legs are about as long as the body in its natural pose 

 (with the abdomen bent) and are scabrous ; the anterior 

 border of the merus and carpus is spiny, the dactylus is 

 nearly half the length of its propodite and has its posterior 

 border almost imperceptibly serrulate. 



The sternum and neighbouring joints of the legs are 

 beautifully iridescent, as also sometimes is the dorsal surface 

 of the bent-up portion of the abdomen. 



Fifty-two specimens from off the Travancore coast, 

 430 faihoms. 



An adult male has the body 26'5 millim. in extreme 

 length and the larger cheliped 38 millim. long. An egg- 

 laden female is 21 millim. long and its chelipeds measure the 

 same. 



Munidopsis Goodrigii, sp. n. 



Differs from all known Indian species in having the eyes 

 absolutely immovable, yet furnished with neither spine nor 

 spinule. Its nearest relative is, perhaps, the Philippine 

 species M. Milleri, Henderson. 



Carapace subquadrangular, convex, slightly broader behind 

 than in front, its regions well delimited, its posterior half 

 deeply sculptured transversely. 



Gastric region with some not very conspicuous squamiform 

 sculpture and with a pair of large spines situated anteriorly ; 

 a spine on either side of, and a pair of spinules in the middle 

 of, the anterior cardiac region. 



Bostrum short, simple, rather slender, smooth. A large 

 acute spine on the anterior margin of the carapace ; lateral 

 borders with two large spines and a spinule, posterior border 

 smooth. 



Abdomen smooth, the second tergum transversely bicari- 

 nate, the third transversely grooved. 



Eyes quite immovable, without spine or spinule. Two
