The rostrum long and thin; the lateral angulations of 
the head are directed obliquely forwards. The eyes are 
round, small, far from the lateral margins. The fagellum of 
the first pair of antenn&e consists of 20 articuli. The first 
pair of antenn&e are as long as the head with the rostrum. 
The segments of the pereion carry each one median, spine- 
like tuberele on the dorsal-side. The lateral margins of the 
segments are all produced into two angulations on each side. 
In the first four segments the lacinie are subequal, in the last 
three ones the posterior lacinie are small. The pleon is pro- 
duced backwards into two flattened angulations, between these 
the uropoda are attached. The uropoda are as long as the 
pleon. The outer ramus is shorter than the inner.

The roSstrum is very short, shorter than the lateral an- 
gulations; the lateral angulations of the head are two on each 
side, directed forwards. The eyes are placed on small tu- 
bercles. Between them is a small median tubercle, corre- 
sponding with the tubercles on the pereional segments. The 
flagellum of the first pair of antenn&e consists of 8 articuli, 
the second one is much elongated. The first pair of an- 
tenne are as long as half the breadth of the head. The se- 
cond pair of antenne are shorter than half the length of 
the body; the flagellum consist of 20 articuli. The segments 
of the pereion carry each one median, obtuse tubercle on the 
dorsal side. The lateral margins of the first segment are
