FISHES OF THE PHILIPPINE ISLANDS AND ADJACENT SEAS 231 



with slender pointed broader based cusp; lower teeth broader, 

 oblique, inner or cutting edge convex or serrated, ending in sharp 

 smooth edged cusp at outward extremity ; nostrils nearly transverse, 

 valve with oblique angular lobe bearing on inner side lobule, inter- 

 narial equals their distance from snout end or less than % of space 

 from mouth. Gill openings small, first about y^ of orbit, last nearly 

 twice wide as first, much wider than fourth, before pectoral. Spi- 

 racles moderate, semilunate, distant li/o times their diameter from 

 orbit. 



Scales somewhat rough, with 5 to 9 converging keels or striae on 

 those of head and shoulders; farther back apices smooth from wear, 

 remains of striae surround base. 



First dorsal reaches little beyond middle in total length, base % of 

 outer pectoral edge, upper angle rounded, acute hind angle extended ; 

 second dorsal long as and height % of first dorsal height, similar, 

 base % of distance from caudal; caudal with well-developed sub- 

 caudal; pectoral wide, acuminate inner angle very long, hind edge 

 otherwise slightly concave ; ventrals reach below second dorsal spine, 

 hind edge concave, ends acute; claspers short, ends slender and 

 pointed with short slender spine near end on outer side. 



Back and flanks brownish, lower surfaces white. A^^iite border on 

 fins and gill covers. Length 875 mm. (Garman.) 



East of Japan.

Depth 7%; head 514. Snout 3 in head; orbit 4, long narrow slit; 

 mouth broadly transverse, slightly convex, each angle with deep 

 groove % to first gill opening; teeth rather fine; upper teeth erect, 

 small, well compressed, rather broadly triangular, directed laterally 

 so inner margin forms cutting edge and outer edge of each tooth 

 deeply notched; large nostrils equal about half of internasal which 

 1% in preoral, nostrils at first third in preoral. Last gill opening 

 longest, above pectoral base. Spiracle large, little above hiiid edge 

 of eyelid and distant about its own length. 



Scales 3 to 6 keeled, many keels often more or less obsolete. 



First dorsal spine inserted midway between snout tip and origin of 

 second dorsal spine, latter much nearer caudal vertebra than hind
