The outer margin of the dactyhis is convex and the segment does 

 not possess the longitudinal carina seen in H. beaupresi. There 

 are two large teeth on the dactylus fitting between three on the 

 fixed finger. The teeth on the latter occupy the whole length of 

 the inner margin and the foremost is often broadly rounded. The 

 palm is rather less than twice as long as the fingers. 



(vii) In the third pair of peraeopods the merus is rather 

 more than 3"5 times as long as wide. The propodus is much 

 narrower than the merus and is from 5'5 to 6 times as long as wide ; 

 at the distal end it is not broader than the dactylus. 



(viii) The pleura of the fourth and fifth abdominal somites 

 are acutely pointed infero-posteriorly.

telson is placed in the middle of its length. The posterior pair is 

 placed very much closer to the anterior pair than to the apex. 



The largest specimen examined is about 24 mm. in length. 



In life the species was closely and elegantly striped with deep 

 blue on a pale grey ground. There was a narrow mid-dorsal stripe 

 of bright yellow on the third abdominal somite and a similar stripe 

 close to the inferior margins of the first three pleura. The tail-fan 

 was transparent olive-green, the uropods were blotched with blue 

 and with milk-white tips. The chelae of the second legs were finely 

 dotted and suffused with green, with 3'ellowish fingers ; the basal 

 segments and the other legs were spotted with blue, the dactyli of 

 the last three pairs being reddish. The eggs were pale brown.
