CLASS PISCES. 141 



Finally, there is one in India with only a single 

 dorsal fin. M. de Lacepede has made his genus As- 



PIDOPHOROIDE of it \ 



Latterly, other groups have been established con- 

 nected partially with the cotti, and partially with the 

 scorpaenae. 



Hemitripterus, Cuv., 



Have the head depressed, and two dorsal fins like the 

 cotti, and their skin is without regular scales, but there 

 are teeth in the palate ; their head is rough and spiny, 

 furnished with many fleshy fibres ; their first dorsal 

 fin is deeply emarginated, which has led to the idea 

 that they had three dorsal fins. 



Only one is known which belongs to North Ame- 

 rica, {Cottus tiipterygius, BL, Schn.,) which is taken 

 with the cod ; from one to two feet long, tinted 

 yellow and red, varied with brown 2 . 



Hemilepidotus, Cuv., 



Have the head nearly like cottus, but they have but 

 one dorsal fin ; there are teeth in the palate, and 

 there are on the body scaly longitudinal bands, se- 



mus, Til., Mem. de Petersb. iv. 12., and Voyage of Krusenstern, pi. 

 lxxxvii. ; Ag. decagonus, Bl. Schn. pi. xxvii. 



1 Cot. monopterygius, Bl. 178. 1. 2. 



2 It is also Cottus acadianus, Pen. Arct. Zool. iii. 371. ; the Cottus 

 hispidus, Bl. Schn. 63. ; the Scorpcena flava, Mitchill, New York 

 Trans, i. 2. 8. ; and perhaps the Scorpcena Americana of Gm. 

 Duhamel, sect. 5. pi. ii. f. 8. ; but this figure must be very bad.
