up, laterodorsal, 4.5 to 5 times in head, 1.5 to 2 times in snout; 

 the interorbital 1.5 to 2 times in eye; the mouth oblique, with 

 large thick lips, the lower jaw slightly included, the posterior 

 angle of maxillary in advance of or beneath front margin of 

 eye; the outer row of teeth in upper jaw enlarged, slightly 

 recurved; the outer row in lower jaw of similar but much 

 smaller teeth; behind outer row in each jaw two or three rows 

 of minute teeth ; no canines ; the body covered with firm ctenoid 

 scales, largest posteriorly, those above pectoral becoming very 

 small toward angle of opercle, where they cease ; the entire head 

 naked and nuchal region naked down to posterior angle of 

 opercles and back to origin of first dorsal ; sometimes there are 

 a few scales before first dorsal; the pectoral bases scaleless 

 and the entire region about ventrals naked, including the breast, 

 the region between ventral and pectoral insertion, and a median 

 strip behind ventrals which may extend to anus; the dorsals 

 small and far apart, of equal height, or first dorsal with a 

 short filamentous tip on second spine, rarely equaling depth, 

 the longest spine or ray twice or a little less than twice in 

 head; the anal may equal but usually is less than second dorsal 

 in height ; the posterior rays of second dorsal and anal are longest 

 but do not reach caudal when depressed, the fins angulate or 

 round-angled posteriorly; the depth of caudal peduncle 2.2 to 

 2.5 times in head and 0.6 to 0.7 of its own length; the caudal 

 broadly rounded, its length f to 0.8 that of head; the pectoral 

 broadly rounded, equal to or a little longer than caudal; the 

 ventrals typical of the genus, 2 to 2.5 in head, and reaching 

 less than halfway to anus; the small anal papilla short and 

 triangular. 



According to Scale the color in life is "dull yellow-brown, 

 uniform whitish on under jaw, eyes blue, fins grayish, 2 an- 

 terior spines silvery white, rays of anal silvery white, caudal 

 washed with dusky at tip." 



Alcoholic specimens are dull yellowish brown, the underside 

 of head paler; the fins somewhat dusky or clear. Some speci- 

 mens have the sides of the head thickly sprinkled with dark 

 brown specks. 



Here described from Scale's four type specimens, and sixty- 

 nine cotypes collected by E. A. Mearns and W. D. Carpenter in 

 May, 1907, from Trinidad River at Baguio, at an approximate 

 elevation of 1,360 meters. These specimens range from 19 to 54 

 millimeters in length. I have also examined twenty-seven
