Description. — Carapace coarsely

 in median line, one on gastric, the 

 other on cardiac region ; a transverse 

 row of four or five small tubercles 

 in front of gastric spine; a spine 

 near middle of each branchial region, 

 with a smaller lateral spine below

 there are, besides, three or four 

 prominent tubercles on the angle 

 which divides the hepatic and 

 pterygostomian regions. Antennal 

 spine very long, reaching beyond 

 rostral horns; the three horns of the

 supraocular spines are well devel-

 three rostral spines, are conspicu-
