 the living fish are thus described by M. Risso. The 

 body presents the red hue of red precipitate of

 embroidered en rose, and ornamented at its origin by 

 a reddish spot ; the iris is ruby red. According to 

 this author, it frequents the sea- weeds in the neigh- 

 6ourhood of the shores during the whole year ; the 

 female spawns in spring; it feeds upon Crustacea 

 and zoophytes, but is little esteemed as food.
