PERIOPHTHALMODON 321 



lower part of snout terminates in a broad, loose, crenately lobed 

 flap of skin, which has two long, teatlike sensory tabs hanging 

 down over the upper lip, which is broad, fleshy, rugose- 

 papillate within; the lower lip rather thin, but with a thick 

 fleshy flap at each angle, connecting with upper lip ; the mouth 

 low, horizontal, the posterior angle of maxillary concealed, be- 

 neath middle of eye; the teeth of upper jaw in two rows, the 

 anterior ones of outer row large, stout, erect, caninif orm ; those 

 of inner row few, small, concealed in the gum and difficult to 

 make out, largely wanting; the teeth in lower jaw similar to 

 those in upper jaw, but smaller, only two near the symphysis at 

 all* caninif orm; the entire body covered with scales which ex- 

 tend forward on cheeks and snout, those below and anterior to 

 nape much smaller; the other scales comparatively large, those 

 on nape not reduced in size ; the pectorals scaled for two-thirds or 

 more of their length and the caudal covered basally with rather 

 large scales for a third of its length ; the height of first dorsal 2.6 

 times the length of its base, 1.77 times in the depth of body, and 

 2.2 times in the length of head; the second dorsal low, angu- 

 late and pointed posteriorly, 2.1 times in depth and 3.2 in head ; 

 the anal of nearly uniform height, the posterior rays longest, 

 angulate, pointed, 1.9 in depth and 2.9 in head; the depth of 

 caudal peduncle 0.7 of its own length, and 2.66 times in head; 

 the round-pointed caudal equals head ; the pectoral shorter than 

 head, in which it goes 1.2 times, its tip elongate-pointed; the 

 thick fleshy ventrals United for two-thirds their length, with a 

 thick, well-developed frenum, about twice in head and nearly 

 1.9 times in distance to anal papilla, which is small, somewhat 

 spatulate, and considerably in advance of anal fin. 



The color in alcohol bluish black on head and upper surface 

 of body, with numerous, black, longitudinal lines on sides, ex- 

 tending downward to margin of belly and running back to caudal, 

 the underparts whitish, probably green in life; the first and 

 second dorsals black, with a narrow, white, upper margin; the 

 anal uniform in color with belly; the caudal nearly black, the 

 lower margin pale ; the pectoral dusky greenish. 



A male specimen, 68 millimeters long, from Perez, Bondoc 

 Peninsula, Tayabas Province, with 11 spines in first dorsal and 

 58 scales in a longitudinal series, was brownish, with seven dark 

 brown, dorsal crossbands, running diagonally forward to middle
