true C. pompilus. They became, in the works of systematic 

 authors, the Black-Ruffe of Pennant, Perca nigra of Gmelin, 

 Holocentrus niger of Lacepede. The two other specimens which 

 fell into the hands of Mr. Couch, and which were described by 

 him in YarrelPs work, were also C. pompilus, as is evident from 

 the number of the fin-rays stated*. 



With regard to Centrolophus morio, Lace'p. (Mr. Couch had 

 marked his sketch with the name of Centrolophus morio 1), 

 Cuvier has examined the typical specimen to which Lacepede had 

 given that denomination. He found it entirely agreeing with 

 C. pompilus, especially with regard to the number of the fin- 

 rays ; and there is not the slightest doubt that C. morio, like 

 C. liparis, Risso, is a nominal species, and synonymous with 

 C. pompilus. 



Finally, Centrolophus crassus, Cuv. and Val., if at all different 

 from C. ovalis, cannot be confounded with our new species, — 

 having the body as high as C. ovalis, and only thirty-nine rays 

 in the dorsal fin. 



Two other British specimens of the Black-fish are mentioned 

 in Yarrell, Brit. Fish. 3rd edit. p. 250 : one came under the 

 observation of the Rev. George Gordon, at Lossiemouth (Moray 

 Firth), the other under that of Mr. Rudd, at Redcar. No other 

 information with regard to these two fishes has been preserved.

Genus Gnathocerus.

The present genus is identical with what I have hitherto cited 

 as Cerandria, — Thunberg's name of Gnathocerus, which until 

 lately appears to have been lost sight of by entomologists, 

 having the priority in point of date. Hence the common Ce- 

 randria cornuta must be quoted as the Gnathocerus cornutus. 

 Another species, detected by myself during the spring of 1859, 

 has been added to our fauna since the publication of my last 

 paper, which I conclude to be coincident (if indeed it be pos- 

 sible to draw any conclusion at all from such meagre descrip- 

 tions as those of Fabricius) with the Trogosita maxillosa of the
