The latter two species form an interesting addition to a section ot 

 the genus Serranus distinguished by the elongation of the last ray 

 of both the dorsal and the anal fin. Two other species of this sec- 

 tion have been described by MM. Cuvier and Valenciennes, to whom 

 they have only very recently become known. Of one of these, Serr. 

 filamentosus, as well as of the two new species above described, spe- 

 ciraens are contained in the Mauritius collection.
