Pleurocaris annulatus g. et sp. n. 
The specimen is without a

the thoracic somites distinct 
and provided with horizon- 
tally expanded pleural plates; 
with at least 7 pairs of the 
thoracic appendages, not 
greatly differing in size; with 
the abdomen longer than the 
thorax; with the telson and 
uropods forming a tail fan— 
the former distinct from the 
Acanthotclson Simpsoni Meck and Worthen 
last somite and tapering to a sharp point, the latter with long, narrow rami.
