No further specimens of .the type-species E. macrura have up to the 

 present been found, but two other specimens have been discovered 

 among the " Pieter Faure " material. One of these is an ovigerous 

 9 , the other is without definite sexual characters, but seems to be an 

 immature <$ . The spiniform process of the 1st antenna may prove to 

 be a male character in this genus.

Male (?). Body very narrow, head and dorsal surface of peraeon 

 pitted. Head longer than broad, with a minute median point. Eyes 

 well developed. Peraeon segments dorsally flat, with a low but 

 distinct lateral keel, segments gradually increasing in length to 5th. 

 6th a little shorter than 5th, 7th half length of 6th, segments 3-6 

 each with a narrow longitudinal pit. Ventral surface rounded. 



Pleon segments 1-5 subequal to 7th peraeon segment, fused but 

 with distinct sutures dorsally and laterally ; no trace of keels but the 

 dorsal surface is flat ; telson half as long again as pleon segments 

 1-5, parallel-sided in its basal half, then tapering, the tapering 

 becoming more rapid on approaching the subacute apex, a median 

 longitudinal keel extending from base to apex, distal margin sparsely
