DE. BAIED ON THE APHEODITACEAN AFNBLIDES. 179 



like the blade of a scimitar at tlie upper half of their length, and 

 strongly toothed on the convex edge for some distance along the 

 upper portion. These teeth are about 14 or 15 in number, and 

 the last, which forms the point, is longer than the others, and 

 sharp pointed. The bristles of the ventral branch are shorter 

 and rather darker coloured than those of the dorsal branch, and are 

 bidentate or forked at the extremity, the teeth vs^hich form the 

 lower part of branch being short and stout. Both branches of 

 feet are stout and blunt-pointed. The under surface of the body 

 is dark brown, and roughened with numerous raised vesicular 

 points. The upper cirri are small ; the inferior are short. 



This species may possibly be the Salithea aurata of Eisso ; but, 

 as I have said before, Hisso's species cannot be determined, and 

 as the particular locality where our specimen (there is only one) 

 was found is not specified, I think it better to distinguish it by 

 a new name.

Eyes sessile, placed upon the basal part of the tentacle, lateral ; 

 no felty covering on the back. Bristles of the dorsal branch of the 

 feet unciaate, not barbed ; those of the ventral branch few in 

 number, bidentate. 



I have not seen any species belonging to this genus. Kinberg. 

 describes only one.
