I or 2 on its lower '; as a rule there are 5 above and 2 below. 

 The hepatic spino of the carapace is absent. The third max- 



illiped (text-rig. 96) is short 

 and stout and does not reach 

 the distal end of the merus 

 of the first peraeopod. The 

 exopod reaches beyond the 

 middle of the last segment. 

 The penultimate segment is 

 about 1 "5 times as long as 

 wide ; the ultimate segment is 

 about 1*3 times the length of 

 the penultimate and is nearly 

 3*5 times as long as wide. 



In the first peraeopods 2 the 

 merus is a little shorter than 

 the carpus and much stouter, 

 the greatest breadth of the 

 former being about 175 times 

 that of the latter. The chela 

 is half as long as the carpus 

 and the fingers are a little 

 shorter than the palm. The 

 second peraeopods (text-fig. 97) 

 are equal or unequal, but are similar in structure. In full-grown 

 specimens the upper border of the merus is strongly convex in later 

 al view and ends in one or two small spines. The lower border 

 ends; on the outer side, in a large sharp tooth. The carpus bears 

 a large tooth veutrally and the upper portion of the distal margin 

 is cut into a series of 3 to 6 small teeth. The chela is swollen and 

 its breadth near the proximal end is twice as great as at the base 

 of the fingers. 3 The palm is twice as long as wide and twice as 

 long as the fingers. The fixed finger (text-fig. gyb) is provided 

 with a large blunt molar tooth which occupies the greater part of 

 the proximal half of its inner edge and the margin in front of 

 this tooth is strongly sinuous. The outer margin of the dactylus 

 forms an almost perfect semicircle ; at the base of its inner margin 

 there is a large cavity to receive the molar tooth of the fixed finger. 

 An exceptionally large specimen is 23 mm. in length, with 

 chela 16 mm. in length. 



Specimens obtained at Port Blair, when alive, resembled Dana's 

 coloured figure. They were pale green throughout, minutely dotted 

 with yellow and dark brown. In ovigerous females there were red 

 streaks on the sides of the abdomen.

Third maxilliped. 



1 Miers refers to a specimen with only 3 teeth above and none below. 



2 This pair of legs in my specimens reaches beyond the scale only by the 

 length of the chela. In Dana's figure they are much longer, but this is doubtless 

 an error. 



a The chela is viewed obliquely in text-fig. 97a and the full breadth of the 

 palm is not shown.
