forwardly and upwardly projecting spine, the post-ocular spine. On either side of the 

 carapace near the anterior end there is a low mound-like projection, from the end of 

 which a strong sharp spine points forwards; these are the hepatic spines. The carapace 

 has one pair of lateral denticles set a little above the lower margin ; immediately below 

 it there is an angle in the margin which Zimmer has incorrectly described as a second 



denticle. 



The lobe at the end of the first segment of the antennular peduncle is large and strong 

 and points upwards and forwards above the second segment ; it is narrower than the 

 second segment and about one-third its length (Fig. i8 a, b). Its distal end is divided 

 by a wide semicircular depression into two sharp and equal points. On the inner side 

 of the dorsal surface of the second segment there is a keel, low proximally, high and 

 produced into a sharp point distally ; on the upper outer distal corner there is a very 

 thick and blunt protuberance. The third segment has a high keel, the front part of it 

 cut away so as to give it a peculiar and characteristic shape ; a keel of a similar shape 

 occurs in E. eximia, E. recurva, E. gibboides, E. fallax and E. miicronata. 



The terga of the first and second abdominal segments are produced into small wide 

 rounded projections mid-dorsally, that of the second wider and more rounded than the 

 first. There is a strong compressed spine-like process from the third segment and 

 smaller spine-like processes, not compressed, from the fourth and fifth segments 

 (Fig. 1 8 c). The hind margins of the terga of the posterior abdominal segments are not 

 deeply incised as they are in E. spinifera and E. longirostris. 



The terminal process of the male copulatory organ has a heavy foot-like base, strongly 

 arched, the heel big and high (Fig. 28 a). The shaft of the process is nearly straight. 

 Near the end it divides into a shorter blunt heavily chitinized part, bent a little out- 

 wards, and a longer flatter blade-like part, with thin walls, bent a little inwards. The 

 distinction between the parts can be seen on the front side before the point of actual 

 bifurcation. The basal part of the proximal process is heavy and rounded, the distal part 

 lighter and bent inwards. Its end is expanded into a large quadrangular plate lying in 

 a vertical plane, most heavily chitinized along its lower margin (the uppermost in the 

 figures). It is deeply incised in line with the axis of the process ; the distal margin of the 

 upper part (the lower in the figures) is crenated. The lateral process is hook-shaped and 

 carries no secondary teeth or processes. On the median lobe, opposite the end of the 

 lateral process and anterior to it, there is a small additional process. 



This description is based on a collection of twenty-one males and twenty-five females 

 from a net hauled horizontally at 200 m. at St. 270, 13° 58V S, 1 1° 43*' E, near Benguela 

 on the west coast of South Africa. The males, all of which had spermatophores and were 

 therefore sexually mature, varied in length from 19 to 25 mm.; the females, five of 

 which carried spermatophores, varied in length from 19 to 27 mm. 



None of the larval stages is known. 



Distribution. Zimmer described the species from a number of females from an 

 unknown locality. Illig records them from five points off the west coast of Africa, 

 from Cape Bojador in 26° N to near Cape Town in 34° S; I have seen those from his
