of maxillary concealed and extending beneath anterior half of 

 eye; the outer row of teeth in lower jaw is horizontal and 

 projects beyond lip so that it is plainly visible; the inner row 

 composed of three hooked canines on each side, the anterior 

 ones largest; the scales before first dorsal extend forward to 

 opposite posterior margin of opercles; the dorsals far apart, 

 the fourth spine of first dorsal longest, -barely touching origin 

 of second dorsal when depressed, a little greater than depth; 

 the second dorsal and anal of similar shape, the posterior rays 

 longest and equal to longest first dorsal spine but not reaching 

 caudal when depressed; the caudal peduncle broad, its depth 

 about 1.9 times in head and 1.8 in its own length; the caudal 

 broad, nearly truncate, 1.2 times head; the pectoral broad, 

 pointed, nearly as long as head ; the broad short ventrals reach 

 less than halfway to the slender pointed anal papilla. 



The color in alcohol everywhere dark purplish brown, with 

 sides of head purplish black and a large violet-black spot cover- 

 ing base of pectorals ; the dorsals, anal, and forward two-thirds 

 of caudal deep velvety black; the pectorals concolorous with 

 body; the ventrals and posterior third of caudal colored like 

 body, with a narrow lateral margin of white. 



Here described from the type specimen, 34 millimeters long, 

 from Irid River, Santa Ines, Rizal Province. 



I place here also three immature specimens, 23 to 28 milli- 

 meters long, from Bangar, La Union Province. They are much 

 paler, being uniform dark slate color all over. 



Ater, black; purpureus, purple.

Dorsal VI, 1-7 ; anal I, 8 ; there are 38 scales in a longitudinal 

 series, 10 in a transverse series, and 13 or 14 rows of scales 

 before first dorsal. 



The body low, slender, elongate, cylindrical anteriorly, the 

 diameter equal to or greater than the depth, laterally compressed 

 from second dorsal back, the depth 5.7 in length; the head 

 flat above, broad, its depth two-thirds of its width, and con- 

 tained 4.4 times in length; the convex snout bluntly rounded, 

 4.5 times in head; the circular eyes high up, lateral, equal to 

 snout, as is also the broad interorbital ; the mouth rather small, 

 slightly oblique, the posterior angle of maxillary beneath an-
