and vcutrally, tho dorsal serrations numbering 8 or 9, the ventral from 3 to 5, 

 all being fixed. 



The 3rd abdominal tcrgum has the posterior border convex, but not acutely 

 produced. The telson is as long as the 5th and Gth abdominal somites combined, 

 t lie (ith somite being short. Of the four spines at the tip of the telson the outer 

 one on either side is of most unusual length, even in the adult, the two forming 

 a conspicuous caudal fork. 



The ocellus is quite indistinct. The antennular peduncle reaches more than 

 halfway along the antenna! scale, the latter being little more than half the length 

 of the carapace proper : the antennular flagella are longer than the combined 

 carapace and rostrum. 



The external maxillipeds are stouter and very much longer than the first 

 pair of legs : the whole of their long terminal joint lies beyond the tip of the 

 antennal scale and almost the whole of their terminal joint lies beyond the 

 extended 1st pair of legs. 



The 1st pair of legs are the shortest of all, and the left leg of the 2nd pair is 

 the longest of all, reaching far beyond the end of the external maxillipeds and 

 being as long as the carapace and rostrum and first 4 abdominal somites com- 

 bined. The right leg of the 2nd pair is also long, reaching just beyond the 

 external maxillipeds and being nearly as long as the legs of the 3rd pair, but it 

 is shorter than its fellow by half the carpus of the latter. Of the last three pairs 

 of legs the 3rd is the longest and the 5th the shortest : in all three the posterior 

 border of the merus is spiny and the succeeding joints are sparsely setose. 



Colours in life pink : eggs light blue.
