groove, especially well marked in this portion of the carapace. 

 The branchiostegal spine is strong and extends forwards be^'-ond 

 the level of the eyestalks. Behind it is another small tooth, placed 

 further forward than any others of the dorsal series. Exclusive 

 of the spines on its frontal margin, there are in all eleven teeth 

 on the carapace: none of these teeth form the terminations of 

 carinae. 



In the male each of the last three thoracic sterna bears a 

 median keel, which ends anteriorly in a small tooth : these keels 

 are absent in the female. The first and second pairs of legs 

 are adjacent at the base in the male and are not separated by the 

 antrorse spine found in P. hendersoni.

The eyes are stout and short. In both sexes the distal mar- 

 gin of the stalk, on its upper and inner side, is produced beyond 

 the cornea to a small but conspicuous papilla. 



The basal segment of the antennular peduncle (text-fig. 4a) 

 bears a stout ventral spine and another at the distal end of its 

 outer margin. The lateral process is peculiar in form. It is fully 

 as long as broad and is furnished anteriorly with two spines, the 

 outermost the largest and the inner bearing a small internal spinule. 

 The outer flagellutn does not appear to be appreciably stouter in the 

 male than in the female and is shorter than the peduncle. 



The antennal scale (text- fig. 46) is broad, its breadth in a large 

 female being more than half its length. The outer margin is con- 

 vex and terminates in a spine which does not reach as far forward 

 as the lamella and is separated from it by a broad U-shaped gap.
