almost as far forwards as the ends of the eyestalks. The latter 
spine is flanked by a short carina which runs obliquely downwards 
and backwards and, above its posterior termination, in the anterior 
quarter of the carapace, there is another well marked spine. Ex- 
cept for this spine and for the carina mentioned above the entire 
surface of the carapace is smooth, save for a feeble transverse 
depression behind the frontal margin. On the sides of the carapace, 
most numerous below the branchiostegal carina, are some long 
silky hairs. 
The thoracic sterna of the female are not carinate. 
The eyes are elongate and their inner margins are contiguous ; 
the cornea is well pigmented and its length in dorsal view is about 
equal to that of the stalk. 
The basal segment of the antennular peduncle (text-fig. 6a)

at its distal end. ‘The lateral process is elongate oval and is fur- 
nished with a minute point anteriorly. The second and third seg- 
ments are about equal in length and the outer flagellum in the 
female is about as long as the peduncle. 
The antennal scale (text-fig. 6b) is about one and two thirds 
as long as broad; the outer margin is very slightly convex and 
terminates in a stout tooth which does not reach nearly as far for- 
wards as the apex of the lamella. 
The outer maxillipedes reach beyond the apex of the scale by 
more than half the length of the ultimate segment. 
The first peraeopods (text-fig. 6c) reach as far forwards as the 
third maxillipedes and do not possess exopods. The merus bears 
a terminal (not sub-terminal) spine at the distal end of its outer 
margin. On the outer and inferior aspect of the carpus there is a 
sharp spine; the inner angle is produced and is provided with a
