Since the publication of Jassa goniamera, A. O. W., Canon A. M. Norman has 
pointed'* out that the genus Jassa, Leach, was restricted by Bruzeliusy to species with 
the upper antennae “ flagella 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 Ischyrocerus, Lillj. and Bruzeliella, 
Norman, in having no secondary teeth on the outer ramus of the third uropocls, it- 
becomes necessary to establish a new genus.
