As the single specimen in the ‘ Southern Cross ’ collection was not dissected, the 
following additional details are given. The specimen from which they are taken was not 
full grown, and differs from the larger in the absence of the prominent convexity of the 
lower part of the fifth side-plate and of the dorsal carina, except on the third pleon 
segment. 
Upper antennae: First joint of the peduncle longer than the remaining two, 
swollen at the base on the lower margin ; second nearly twice as long as the third ; 
both have the upper margin produced and notched. Flagellum 28-jointed. 
Lower antennae : Basal joint produced on the inner side beyond the first joint, the 
upper margin in both forming an acute tooth ; second joint rather longer and thicker 
than the third, the upper margin of which is produced and notched. 
Mandibles: The palp stout, the second joint longer than the third, otherwise the 
mouth organs and maxillipeds are nearly as in E. cornigera (Fabr.). 
Gnathopods nearly resemble those of E. cornigera; the hand of the second pair is 
shorter and wider at the distal end than that of the first, and is finely denticulate at 
the rounded and spinous palmar angle. 
Third perseopods: Side plates rhomboidal; first joint with a long tooth-like 
process directed downwards from the upper part of the hind margin, which terminates 
in a sharp tooth. 
Fourth perseopods like the third, except the side plate. 
Fifth perseopods: Side plates rather wider at the top than the widest part of the 
first joint, narrowing downwards ; first joint expanded above, narrowing abruptly near 
the middle, whence the hind margin curves outwards and ends in a tooth. 
First uropods: Rami subequal, longer than the peduncle, narrow lanceolate, 
fringed with short spines on both margins. 
Second uropods : Inner ramus not reaching the end of the first uropods ; outer less 
than half as long and much narrower than the inner. 
Third uropods not reaching the end of the longer ramus of the second pair, 
broadly lanceolate, subequal, longer than the peduncle, which has a prominent tooth. 
Telson reaching to the base of the rami of the third uropods, tapering considerably 
and notched at the tip. 
Length of the specimen described, 25 mm.

All the segments of mesosome and pleon, with the exception of the first two 
segments, of which the first is twice as long as the second, armed with lateral teeth, 
increasing in length backwards, with longer dorsal teeth, curved and directed upwards 
and backwards ; those of the last mesosome and first two pleon segments the longest.
