264 CLASSIFICATION OF FISHES, ETC. 



with many of tlie rays but slightly connected by the 

 membrane ; pectoral rays deeply cleft ; no pectoral 

 appendages, as in some of the Apisti; head with 

 short spines and fleshy lobes or cirri ; no teeth on 

 the palate ; dorsal fins two, equal, but united ; 

 ventrals very large. 



Pterois Cuv. Dorsal fins very high ; pectoral fins as 

 long as the body, or reaching to the base of the 

 caudal fin ; the upper rays, as well as those of the 

 first dorsal fin, deeply cleft ; caudal small, sub-lan- 

 ceolate j mouth opening horizontally.'

 pi. 85. antennaria. Bloch, pi. 185. 



Macrocliyrus Sw. Pectoral fins only one third as long 

 as the body ; in other respects resembles the last, but 

 the mouth is subvertical. 



miles. Benn. Cey. pi. 9. 



Pterohptus Sw. Pectoral fins very long, reaching to 

 the base of the caudal, but the rays are not cleft, as 

 in the two last ; first dorsal fin with the rays very 

 high, and only connected by a membrane at their 

 base ; mouth oblique. 



P. longicauda, Russ. ii. pi. 133. 



Pteropterus Sw. General structure of Pterois, but 

 • the dorsal fin is very low *, a doubtful type. 

 T. radlatus. Cuv. and Val. 



Brachyrus Sw. Pectoral fins short, only one third the 

 length of the body ; the first eight branched, the re- 

 mainder simple, and all united nearly to the tips by 

 the membrane, 

 zebra. Cuv. iv. p. 367. brachj^terus. lb. iv. p. 368. 



Apistes. Pectoral fins moderately large ; the rays un- 

 divided, and all of them branched, with a digitated 



* This tvpe, if such it be, rests on the authority of a drawing by Parkin- 

 son in the'Banksian Library. I do not think it probable that the dorsal 

 rays, as conjectured by Cuvier, had been broken off, for Parkinson was a 

 zoological painter, and would have been aware of the circumstance.
