Remarks. 01 the nine specimens which I refer to this species, three are egg- 

 bearing females and six are males. They were collected between the end of 

 January and the end of April, which presumably covers the breeding season 

 of the species in the Red Sea. With the exception of the form of the first 

 pair of legs, there is very little to add to Coutiere's description. The rostrum 

 shows some variation in length, but in all the specimens it is longer than the 

 first two segments of the antennular peduncle and never exceeds the whole 

 length of the latter. The supra-, extra- and infra-ocular spines agree very 

 closely iu form and relative proportions with Coutiere's figures, and the 

 stylocerite in all the specimens reaches as far forward as the distal end of 

 the second joint of the antennular peduncle. One of the female specimens 

 still retains one of the first pair of legs (the left), and this appendage is in 

 close agreement with Coutiere's figure 129/. Among the male specimens, 

 imperfect as they are, I have noted some interesting points in the form of 

 the first pair of legs. I should explain that I have relied for the deter- 

 mination of the sex of the specimens on the presence of an appendix 

 masculina on the second pleopods, which is well developed on all the male
