seems to have I 6 pelvic rays, and is otherwise very similar 

 to Hoplostethus or Trachichthys. 



Family 8. Holocentridse. 



A long spinous dorsal ; anal with 4 spines ; caudal with 

 17 branched rays; pelvics thoracic, of a spine and 5 to 8 soft 

 rays. Jaws and dentition as in the Berycidae ; two supra- 

 niaxillarie?, the posterior large and sending forward a pointed 

 process above the small anterior one ; subocular shelf formed 

 by several suborbitals ; nasals moderate, separated by the 

 prsemaxillary processes, not convergent anteriorly; a second

overlapping the parietals and supra-occipital, which scarcely 

 appear on the dorsal surface of the cranium ; no parietal 

 crests; occipital crest not extending on to the frontals, which 

 have a pair ot low longitudinal ridges bordering a median 

 groove or channel, and posteriorly a varying number of ridges 

 radiating backwards ; trunk-muscles inserted only on poste- 

 rior surface of skull, excavating large posterior temporal 

 fossae, which are roofed by the frontals. Ilypocoracoids 

 narrowed forward below, not reaching the ventral profile, not 

 embracing the pelvic bones, which are loosely attached by 

 ligament above the symphysis of the cleithra. Vertebrae 26 

 or 27 ; no upturned centra, and the anterior uroneural anky- 

 losed with the last centrum.
