The rostrum is much longer than the head (7:35); the 
lateral angulations of the head are directed obliquely for- 
wards, they are longer than the head. The eyes are oval. 
The long diameter of the eyes equals a sixth of the length 
of the head. The flagellum of the first pair of antenn&e is 
60 to 70-articulated. The first pair of antenn&e are nearly as 
long as the breadth of the head (18:19). The flagellum of 
the second pair of antenn&e consists of almost 280 articuli. 
The first segment of the pereion is as long as the second; 
the seventh segment is the longest. All carry each two 
spine-like tubercles on the dorsal side. The lateral margins 
of the first segment carry one angulation on each side, the 
second, third, and fourth two, more or less equal, the fifth, 
sixth, and seventh one large and one very minute each. 
The pleon carries on its dorsal-side a single spine-like tu- 
bercle, and is produced backwards into two flattened, sharp- 
pointed angulations, between these the uropoda are attached. 
The peduncles of the uropoda are shorter than the angula- 
tions. The outer ramus is almost as long as the inner 
(FT=330): 
Colour. Yellowish white. 
Length. 21,5 mm.

The differences between this species and the preceding : 
are many, but not of great importance, with the exception 
of the characteristics from the flagella of the antenn&, and the 
spine-like tuberele on the pleon, which charcteristics probably 
are of specific value.
