Since the publication of Jassa goniamera, A. O. W., Canon A. M. Norman has 
pointed* out that the genus Jussa, Leach, was restricted by Bruzeliusf to species with 
the upper antenne “flagello appendiculari destitute,” or, as is the case with his type 
species J. capillata (Rathke), having only a rudimentary appendage. As J. goniamera 
has a well-developed appendage, but differs from /schyrocerus, Lill}. and Bruzeliella, 
Norman, in having no secondary teeth on the outer ramus of the third uropods, it 
becomes necessary to establish a new genus.
