The presence of the appendix interna on the first pair of pleo- 

 pods is a very remarkable character of this genus and one in which 

 it differs, I believe, from all other known Caridea. It should be 

 noted, however, that the appendix is to be found on the first 

 pleopods in males only, not in both sexes as implied by Borradaile.

This species was described by Borradaile from Suvadiva, 

 Kolumadulu and Haddumati Atolls in the Maldives. It is here 

 recorded from the Orissa Coast, the Andaman Is. and the Mergui 

 Archipelago. 



Specimens from the Andamans were transparent when alive 

 with brown speckling and with narrow transverse brown bands at 

 the end of the carapace and on the second and third abdominal 

 somites. There were brown patches in the middle and at the tip of 

 the rostrum, on each side of the first abdominal somite, at the tips 

 of the telson and uropods and at the base of the uropods. The 

 antennules, antennae and all the legs were broadly banded with 

 red. 



The largest specimens in the collection are ovigerous females 

 about 30 mm. in length.

The specimens from Port Blair were caught in bottom nets 

 hauled in Ross Channel and at the mouth of Brigade Creek ; those 

 from the Mergui Archipelago, none of which are fully adult, were 

 obtained at night in surface nets.

Borradaile includes twelve species in this genus, but except for 

 the two originally described by Dana and the three that Borradaile 

 himself named, all require re-examination. In general appearance
