Unciola 677 



palp long. Maxiila 2, inner plate with lateral fringe. Maxillipeds normal; 

 outer plates broad, with rather sti'ong spine-teeth. Gnathopod 1 much the 

 stronger, differing to some extent in the 2 sexes, subchelate; the finger 

 setose ou outer margin. Gnathopod 2 feebly or sometimes scarcely sub- 

 chelate. Peraeopods 1 — 5 rather slender; 2*^ Joint little expauded, finger 

 with setules on inner margin. Pleopods with strongly serrate coupling spines 

 on Short, rather stout peduncle. üropods 1 and 2 biramous, stout, with 

 strong spines. Uropod 3 very short, with small outer ramus; the inner never 

 articulated, but sometimes mai-ked off from peduncle, at other times represented 

 only by backward Prolongation of peduncle. Telson lamellar, rounded.
