292 On Indian Deep-sea Crustacea. 



first pair of legs, and nearly as long as the combined carapace 

 and rostrum ; their ischium and merus are compressed and 

 somewhat broadened. 



Except for a few spinules on the carpus of the great 

 cheliped the legs are smooth. 



The first three pair of legs are truly chelate and the last 

 two pair are apparently so, since their small dactylus ends in 

 a pair of claws. 



The first pair is slender. [The second pair is broken off 

 in our single specimen.] The third pair is of,Alphean 

 odclness, the left being slender and non-elongate, while the 

 right is nearly as long as the body without the telson and is 

 very massive, especially as regards the hand. The last two 

 pair have a three-joint carpus and a two-joint propodite. 



The abdomen is perfectly smooth except for the telson, 

 which is longitudinally divided into two lobes by a deep 

 groove, the strong convexity of each groove being spiny. 



The first pair of abdominal legs in the female are uni- 

 ramous, the last pair (swimmeret) have the outer edge of the 

 outer lobe serrated. 



The single specimen, which is an egg-laden female, 

 measures 26 millim. from the tip of the rostrum to the tip of 

 the telson. 



The eggs are few and are of very large size — nearly 

 l - 5 millim. in diameter after contraction in spirit.

Three very fine specimens from the Andaman Sea, 185 

 and 370-419 fathoms. They undoubtedly came from the 

 depths.

Two specimens from the Andaman Sea, 498 and 172-303 

 fathoms. Though they came up in the trawl they were 

 accompanied by such pelagic forms as Salpa, Pyrosoma, and 

 Firuloides, with which no doubt they were associated in life,
