FISHES OF HAWAIIAN ISLANDS. 
t>3 
This description from a large example (No. 03599), 8.75 inches long, taken at Hilo. Many speci¬ 
mens were obtained from Hilo and Honolulu. We can not separate T. limbalus from T. trachmus of 
Japan or 7. mtjops of the Atlantic. Probably all constitute a single species.

teeth; lower pharyngeals separate; body elongate, subterete; head depressed; snout triangular, rather 
pointed; interorbital region transversely concave; mouth very wide; premaxillaries not protractile, 
very long and strong, more than half length of head,; maxiliaries closely connected with premaxil¬ 
laries, very small or obsolete; premaxillaries with 1 or 2 series of large, compressed, knife-shaped 
teeth, the inner and larger depressible; palatine teeth similar, smaller, in a single broad band; lower 
jaw with a band of rather large teeth, the inner and larger ones depressible; a patch of strong, depres¬ 
sible teeth on tongue in front, a long row 1 along the hyoid bone; jaw's nearly equal in front; eye rather 
large, anterior; supraorbital forming a projection above the eye; pseudobranchim well developed;

Two species known from the Hawaiian Islands, the one here described and a deep-water form 
(Synodus kaianus), described in Section II.
