in upper arch of lateral line and 6 pores in horizontal hind section 
to caudal base; 5 scales above lateral line to spinous dorsal origin, 
9 below to spinous anal origin; 22 predorsal scales; snout, 2% in head; 
eye, 34; maxillary, 32; interorbital, 22. Teeth uniserial truncate

Color in alcohol. with back prout’s-brown, fading paler or somewhat 
tawny-olive on side and lower region. Dorsals, anals, and ventrals

Compared with the type in the Academy and found only to vary 
in color. Traces of the dark blotch at pectoral base evident in Cebu 
example, though much more faded on right side. The type is much 
more contrasted, as shown in the original figure. This does not 
show the black blotch at bases of last dorsal rays, though it is still 
evident on the specimen, but more distinct on the right than on the 
left side.
