Distribution. The type specimen was collected in shallow water off New Year Island, Falkland 

 Islands; those of the Discovery collections were collected in slightly deeper water (between 341 and 

 290 m. as compared with 36 m. in practically the same locality).

Remarks. This species has not been recorded since it was first described by Ohlin in 1901 from 

 a single female, measuring 7 mm. in length and 4 mm. in greatest breadth. The Discovery collections 

 contain a number of mature specimens of both sexes ; of these, the males are the larger, measuring 

 9 mm. in length and 5 mm. in greatest breadth; the mature females are approximately the same size 

 as Ohlin's specimen. 



Ohhn's estimate of the length of the eye-stalks (p. 298) is too high; they are not 'nearly as long as 

 the peduncle of the antennules ' as he suggested, but about the length of the first two joints. 



The form of the coxae and of the brood pouch in the breeding female has already been dealt with 

 in the introduction to the genus (pp. 154-158). 



The male characters are very like those already described for E. bilobata, the flagellum of the 

 antennule bears many more sensory setae than does that of the female. The penis (Text-fig. i b) is 

 single, broad, rounded and distally cleft; the appendix masculina bears a very close resemblance to 

 that of E. bilobata (Text-fig. 8e).
