Body elevated, its depth being always considerably more than one- 

 half of the total length ; in very young examples the vertical dia- 

 me!er even exceeds the longitudinal. Skin rough, minutely granu- 

 laied. With age a hump is developod above the mouth, topped by 

 an osseous tubercle, which in very young examples is a spine. 

 Dorsal and anal fins narrow, high, becoming comparatively shorter 

 with age. A series of more or less conspicuous ossifications on the 

 posterior edge of the caudal fin. Very young examples with scat- 

 tered spines, some of which ai^e permanent through Kfe as osseous 

 tubercles — for instance, at the throat. Eye much nearer to the upper 

 profile than to the lower. 



A pelagic fish, probably inhabiting most of the seas of the tem- 

 perate and tropical regions.
