CLASSIFICATION OF FISHES^ ETC. 



Capriscus Antiq., 

 AVm. Caudal 

 fin truncate or 

 rounded ; pel- ^^ 

 vis slightly pro- 

 jecting, but 

 destitute of 

 rays ; dorsal 

 spine obtuse and tuberculated ; teeth entire. 



erythropterus. Less. Atl. rivulatus. Riipp. Atl. ii. 16. 2. 



fiff. 3. (Jig. 104. ) castaneus. Tnd. Z. i. pi. 9a 2. 



10. 



o' 



Rondelettii. Yarrell, ii. 357. niger S'ii?. Appendix. 



Leiurus Sw. Pelvis forming a large ventral fin pro- 

 vided with distinct rays ; dorsal spines acute and 

 smooth ; caudal small, doubly lunate j teeth longest 

 in front, and sometimes notched in the middle. 



L. macrophthalmus. Russ. pi. 22. radiatus, Bowdich, Mad. 

 Russellii. lb. pi. 23. pi. 17. fig. 45. 



Pachynathus* Sw. Body short, broad, compressed; 

 the head very large, and nearly as long as the body ; 

 eyes very remote from the mouth, placed high upon 

 the crown, and immediately above the pectoral fins ; 

 front teeth remarkably long ; first dorsal spine obtuse 

 and rough ; pelvis with minute rays ; caudal doubly 

 lunate. 



P. triangularis. Russell, pi. 20. 



Triacanthus Cuv. Ventrals represented by two large 

 spinous rays attached to the pelvis, which does not 

 project beyond the skin ; dorsal fins two, the first 

 with spined rays ; body with minute prickles, shaped 

 as in Balistes, but the taO. much lengthened ; the 

 caudal forked. 



T. biaculeatus. Bloch, pi. 148. fig. 2. 



* I have had much hesitation in characterising this as a subgeneric type ; 

 but it differs so remarkably in its long, yet conic muzzle, that I am tempted 

 to think it may be the chironectiform type of this genus, corresponding to 

 Psilocephalus : the eye is so remote from the tip of the snout aa to be nearly 

 half way between that and the base of the caudal fin.
