Postero-inferior angle of the three anterior segments of the pleon 

 rounded. Eyes reniform. Superior antennae nearly half as long 

 as the animal ; peduncle about half as long as the flageUum ; 

 secondary appendage triarticulate. Inferior antennae about half 

 the length of the superior ; peduncle rather longer than the 

 flagellum. Gnathopoda subequal : propodos of the first pair long- 

 ovate, pahn oblique, defined by a single spine ; propodos of the 

 second pair ovate, palm scarcely oblique, emarginate (both pairs 

 are slightly smaller in the female). Posterior pair of pleopoda 

 much longer than the preceding, having one ramus long and spi- 

 nous, the other very short and spinous. Telson can-jing, at the 

 extremity of each section, two or three short spines and a single 

 short plumose hair. The colour of the animal is oKve-green, but 

 occasionally one may be found of a greenish-yellow. Under the 

 microscope the integument is seen to be studded aU over with 

 short straight h-^irs, that spring from a tube enlarged at each 

 extremity.
