FISHES OF THE PHH.IPPINE ISLANDS AND ADJACENT SEAS 251 



Skin with small hispid asperities, each as simple little point, on 

 tail form longitudinal rows which narrow to 10 along least depth 

 of caudal peduncle. Fins naked, hispid points extend only over 

 basal areas broadly ; small smooth areas behind dorsals, ventrals, and 

 pectorals ; lips, spiracles, nostrils, and gills also naked. 



First dorsal length 13^4 in head, inserted little nearer snout tip than 

 upper caudal origin, spine 1% in second dorsal spine which slightly 

 greater than interorbital ; second dorsal length 1% in head, longer 

 than jQrst dorsal; caudal 314 in rest of body; subcaudal lobe longer 

 than second dorsal; pectoral 2 in head, broad basal length % fin 

 length; ventral 1% in head, small, base extending little posterior to 

 second dorsal origin. 



Dark brown, belly slightly darker than upper surface. Dorsals 

 dull blackish basally, broadly wliitish terminally. Other fins dark 

 basally and paler terminally. Iris neutral dusky, pupil pale brown- 

 ish. Gill opening blackish.

 edge of upper jaw about last third in eye; groove outside each mouth 

 corner forms deep pit or socket; upper teeth erect, quincuspid, me- 

 dian cusp longest, slender; lower teeth all directed laterally, outer 

 edge with single deep notch; nostrils lateral on snout below, equal 

 internasal, placed at first fourth of preoral ; each with 2 short, obso- 

 lete fleshy points. Last gill opening before pectoral base, first 

 largest, or y^ of interorbital. Spiracle little elevated from eye and 

 distant space Yq of interorbital, length 4% in same.
