 length. Sides of cephalic somite greatly produced to cover basal 

 parts of oral appendages; oral field greatly produced. No ventro-

 running into short rostrum (fig. 1326). Rostrum triangular, as long 

 as 1st antennular segment, apex rounded, with two minor incisions 

 carrying hairs of frontal organ. Thoracic somites 2 to 4 of equal 

 length, epimeral plates distinct, rounded, bordered with spinules. 

 5th thoracic somite nearly as long as preceding somites, dorsal part 

 of distal border fringed with fine, spiniform hairs. 



Genital somite composed of fused somites 1 and 2, line of fusion 

 distinct on dorsal surface. 3rd abdominal somite fully as long as 2nd, 

 both with laterocaudally produced epimeral plates, bordered with 

 spinules. Exact shape of laterocaudal projection can best be judged
