Species of Fishes from Morocco. 231 



of the species described as being allied to Serranus cahrilla or 

 Serranus sci'iba, tlie scales being considerably smaller than in 

 any of those species. There are eleven scales in a transverse 

 series between the dorsal fin and the lateral line. The height 

 of the body is two sevenths of the total leng-th (without caudal) , 

 the length of the head one third. Snout scaleless, pointed, 

 with the lower jaw slightly prominent, the maxillary extending 

 beyond the vertical from the middle of the eye. The diameter 

 of the eye is two ninths of the length of the head and two 

 thirds of that of the snout. Interorbital space flat, much less 

 than the diameter of the eye. The serrature round the angle 

 of the pra3operculum is much coarser than on the remainder 

 of the bone. The fourth, fifth, and sixth dorsal spines are the 

 longest. Ventral fin terminating at a great distance from the 

 vent ; caudal truncated. Reddish olive (in spirit), with several 

 dark cross bands, most distinct in the middle of the side of 

 the body ; two of them are darker and broader than the rest, 

 and occupy the middle of the body. An oblique dark streak 

 from the eye to tlie angle of the prseoperculum. The soft 

 vertical fins with numerous very small bluish ocelli. Comers 

 of the caudal fin deep black. 



I find that the specimen from Mogador is identical with 

 others in the British ]\Iuseum from the Azores, Madeira, and 

 the Canary Islands (TenerifFe) which I have hitherto confounded 

 with S. cahrilla.

The osseous dorsal ray is strong, smooth, its stiff portion 

 being two thirds as long as the head. There are tAvo and a 

 half or three series of scales between the lateral line and the 

 root of the ventral fin. The height of the body is a little more 

 than the length of the liead, which is one fourth of the total 

 (without caudal). Snout moderately produced, obtusely conical. 

 Mouth inferior ; lips not thickened ; barbels longer than the 

 eye. The origin of tlie dorsal fin is distinctly in front of the 

 root of the ventral, and nearly midway between the end of the 

 snout and the root of the caudal. Caudal fin deeply forked. 

 Coloration uniform. 



This species inhabits the river Tcnsift. The largest of the 

 three specimens examined is 8^ inches long.
