compressed laterally. There are 55 to 60 scales in a lateral 

 series, 17 to 20 in a transverse series, and 40 to 45 between 

 the dorsal fin and the tip of the snout ; on each side of the scaled 

 interorbital space is a broad naked furrow, between which and 

 the eye is a single row of small scales; minute scales extend 

 upon the pectoral and caudal fins; the small villiform teeth in 

 broad bands in each jaw, without canines ; the teeth of the outer 

 and innermost rows may be slightly enlarged ; cheeks large, full, 

 completely scaled, with two or more longitudinal furrows; a 

 prominent groove runs from eye back to upper posterior angle 

 of opercles. The vertical fins low, the dorsals well separated. 

 Dorsal VI, 1-8 or 9; anal I, 8 or 9. The pectoral very broad, 

 the caudal large and gently rounded. The gill openings wide, 

 the isthmus moderately broad. 



This genus is easily separated from Eleotris by the absence of 

 a preopercular spine; from Ophiocara, it differs in scales and 

 teeth ; from Boroda it differs most in the character of the teeth ; 

 from both it differs in lacking pores on the head, and in the 

 arrangement of the scales and naked grooves on the head. The 

 genus is widely distributed in the Philippines, in rivers near 

 the sea. Generic type, Bunaka pinguis sp. nov. 



Bunaka is from bunak, a Negrito name for the only species 

 known.

Ilocano name, boto-bot; the Negrito name, in Nueva Vizcaya, 

 near Casiguran, is bunak. 



Dorsal VI, 1-8 or 9 ; anal I, 8 ; there are from 56 to 58 scales in 

 a longitudinal series from angle of opercle to caudal, and 17 in a 

 transverse series from origin of second dorsal to that of anal (one 

 specimen has 19 on one side) ; there are 42 scales before the 

 dorsal fin and 6 or 7 rows between the naked grooves on interor- 

 bital space; a single row of small scales between the eye and 

 the naked groove. 



This is a very thickset and robust fish with a round, plump 

 body, depressed head, full cheeks, and the posterior third of 

 body strongly compressed laterally; the depth contained 4 to 

 4.6 times in the length; the head very large, its breadth equal 

 or almost equal to depth of body and its length contained 2.8 

 to 3 times in head and trunk together ; the eye 6.5 to 7.5 times 

 in head and 1.4 to 1.6 times in the low, broadly rounded snout; 

 the top of snout has a strong hump, behind which is a transverse
