FISHES OF THK PHILIPPINE ISLANDS AND ADJACENT SEAS 27 



opening or interorbital width; teeth with 7 acute, pointed cusps, 

 central twice high as others ; hiteral cusps graduated smaller toward 

 outer edges of tooth ; nostrils with pointed marginal flaps, meet and 

 curve inward so nasal cavity tubelike with outer and posterior open- 

 ing; internarial between outer anterior nasal openings equals mouth 

 cleft along upper jaw or space between front eye edge and spiracle; 

 internarial between posterior nasal openings equals half horizontal 

 eye diameter. Gill openings equidistant, fifth shortest and above 

 pectoral base. Spiracle level with and close behind eye, its width 

 equals its distance behind eye. 



Scales trilobed, minute, each with central keel. Upper edge of tail 

 with keel beginning eye diameter behind second dorsal base and 

 extends posteriorly space somewhat greater than head; keel armed 

 by 2 rows of enlarged, toothlike scales like those on body between 

 rows of larger ones. 



First dorsal origin about opposite last % of ventral base, front 

 fin edge 1% in head; second dorsal inserted over last % in anal 

 length, front fin edge 1% in head ; anal length equals head, front fin 

 edge 21/3; caudal 2^4 in rest of body, subcaudal trifle higher than 

 anal, with notch little before last fifth; pectoral obtuse, reaches 

 1% to ventral, width I1/3 its length which 11/3 in head; ventral 

 length 11/0. 



Brownish above, with indistinct deeper clouding, more conspicuous 

 above and little behind pectoral base, midway between pectoral and 

 ventral, below dorsal bases, on upper edge of tail and on caudal. 

 Tongue and inside mouth without dusky. Dorsals dusky, front edges 

 dark brown. Free edges of dorsals and anal white. Front caudal, 

 anal and pectoral edges dark brown. Pectorals dusky above, free 

 edges white. Length, 345 mm. (Jordan and Snyder.)

Snout short, from front eye edge less than interorbital; preoral 

 length less than mouth width. 



Upper surface of body rough, scales moderately large, prominent, 

 each with median point longest. 



Dorsals equally large, each long as base length, rounded; second 

 dorsal reaches over and beyond beginning of marginal caudal den- 

 ticles; anal distant from subcaudal origin y^ its basal length; pec- 

 toral short, reaches less than halfway to ventral; ventral short, 

 broad.
