1862.] OF FISHES FROM MADERIA. 177 



specimens of S. herthelotii that have occurred. The fishermen give 



to both these species the name of " Praga." 



The total length of the specimen (which was taken in the month 



of April last) is Hy'^j inches ; the height between the ventrals and 



the vent is Sfxr inches, and its thickness thereabouts is W inch.

Fam. TaiGLiDiE. 

 Setarches, gen. nov. (PL XXIII.) 



Head and body compressed ; no transverse groove at the occiput ; 

 vertex without spines ; preoperculum armed ; body covered with 

 cycloid scales ; without skinny appendages. One dorsal fin divided 

 by a notch into a spinous and a soft portion. No pectoral appen- 

 dages. Villiform teeth in the jaws, on the vomer, and on the pala- 

 tine bones. Lateral line a broad scaleless groove. Six or seven 

 branchiostegal rays. Pyloric appendages in small number. No air- 

 bladder. 



It will be observed that this new genus is closely related to Sebastes 

 and Scorpcena, but more nearly to the former than to the latter. 

 From both it is distinguished by the cycloid scales, the scaleless 

 lateral line, and the absence of spines from the vertex. The single 

 individual on which it has been founded was taken in the month of 

 December 1861, and is now in the British Museum. It was at first 

 assigned to the genus Sebastes, but was at once discriminated from 

 all the species of that genus previously taken at Madeira. "With 

 these species I shall compare it throughout my description, with the 

 view of aiding other observers in identifying specimens, if they should 

 occur.
