Description. — In general aspect and most features closely allied to E. gibba G. O. 

 Sars. Frontal plate very short; rostrum oblong-triangular, somewhat acuminate and very acute, 

 about as long as the breadth of second antennular joint and scarcely as long as the diameter 

 of the small eyes. Lobe from first antennular joint (fig. \a) not half as broad as the end of 

 the joint, directed obliquely forwards, upwards and somewhat outwards, not quite as long as 

 broad, somewhat oblique-triangular with the inner margin feebly convex, the end acute and 

 generally with an extremely low tooth or rather sharp, protruding angle near the base on the 

 outer side. Second antennular joint above with the distal inner angle showing an extremely 

 small, sharp tooth, while at the outer side the lateral corner itself is rounded, but a low, sharp 

 angle projecting forwards is seen above a little inside the lateral margin of the joint. Third 

 antennular joint, seen from the outer side (fig. \a), with the dorsal carina (c.) disappearing nearly 

 suddenly at a considerable distance from the second joint, the upper margin of the carina 

 proximally bending almost suddenly downwards. Dorsal process of third abdominal segment, 

 seen from above, shaped as an oblong-triangular, distally acuminate and very acute plate, which 

 is far from being half as long as the next segment (figs. \b — \c). Sixth abdominal segment 

 nearly twice as long as deep (fig. \ö) and keeping scarcely the same depth to not far from 

 the end, and then the lower margin is curved considerably upwards; the anal spine in the male 

 is small, slender and simple, in the female larger, much broader, compressed and terminating 

 in three or four spiniform branches. Exopod of uropods very little shorter than the telson and 

 slightly or scarcely longer than the endopod. 



The copulatory organs (figs. \d and \é) have the main plate, the inner, the auxiliary 

 and the setiferous lobes shaped nearly as in E. tenera. The terminal process {Jr.) is of very 

 moderate length, distally ending in two short, acute branches, the inner curved and longer than 

 the other which is slender and spiniform ; the foot ( f.) is very long, and the heel (//.) long and 

 distinctly curved. The proximal process (/> s .) is long, reaching much beyond the terminal ; the 

 short basal part is much inflated and protruding outwards; its major part is somewhat curved, 

 before the middle with the inner margin convex and then a little sinuate, moderately strong 

 and keeping the breadth to near the acute end, but the most distal part is compressed and
