than the suboperculum. The tiirbinal bones are elongate tubes. 

 The bones of the infraorbital ring are veiy thin, membranaceous ; 

 the priieorbital is oblong, its longest diameter being in the direction 

 from the orbit to the jaw-bones. The suprascapula is fixed to the 

 skull by two styliform processes ; the scapula is narrow ; the lower 

 part of the humerus and the ulna are very long, with an open slit 

 between them. Each pubic bone is composed of three narrow la- 

 meUfe. 



There are ten abdominal and fourteen caudal vertebra;, the length 

 of the former portion of the vertebral coli;mn being to that of the 

 latter as 1 : 2-1. The four anterior vertebraj are much compressed 

 in their longitudinal diameter, and Cuvier has overlooked the fii-st, 

 stating only nine abdominal vertebrae. The neurals and haemals are 

 strong and more or less erect, especially those of the caudal portion. 

 The intemeurals and interliaemals are well developed. The first in- 

 terhaemal is exceedingly long, extending upwards to the base of the 

 haemal, to which it is joined ; inferiorly, it has a flat triangular pro- 

 minence, pointing forwards. 



It is quite evident, from an examination of the skeleton, that this 

 species is a true Caranx, The bones which form the base of the 

 spinous dorsal are very close together, and consequently the spinous 

 rays cannot be so well developed as in the other species. They are, 

 however, present, and the specimen described exhibits distinctly six 

 small dorsal spines.

 The teeth in both the jaws form villiform bands ; teeth on the 

 vomer and the palatine bones. The first dorsal has entirely dis- 

 . appeared ; none of the rays elongate. The height of the body is 2|, 

 the length of the head four times in the total. The snout is elevated, 

 rather obtuse, with the lower jaw longest. The lateral line is bent, 

 and becomes straight below the middle of the soft dorsal ; plates small 

 and few in number. Silvery: axil black. {Ciw.)

Body much compressed and elevated ; cleft of the mouth moderate. 

 Praeorbital very high. The first dorsal continuous, sometimes rudi- 

 mentary, the second dorsal and anal more developed ; anal spines 

 none, or separated fi-om the soft fin by an interspace. Scales none, 

 or very rudimentary ; lateral line with an anterior curve and with a 

 posterior straight portion, ■without any plate-like scales. Dentition
