behind which are two rows of minute depressible teeth; no 

 canines; the body moderately elongate, compressed above, with 

 large ctenoid scales, 30 to 32 in a longitudinal series; the head 

 large, naked, with prominent longitudinal lines of minute warts 

 on cheeks. Dorsals VI, 1-9, the second spine of first dorsal 

 elongated ; anal I, 9 ; no silky rays on upper part of pectoral ; 

 the rounded caudal shorter than head. 



Only a single species is known of this Philippine genus.

PLATE 21, FIG. 3 



Illana cacabet SMITH and SEALE, Proc. Biol. Soc. Washington 19 

 (1906) 80, with text figure. 



Dorsal VI, 1-9 ; anal I, 9 ; there are 30 to 32 scales in a longi- 

 tudinal series, 10 in a transverse series, and 13 before first 

 dorsal. 



The body elongate, laterally compressed with long, slender 

 caudal peduncle, the dorsal profile well arched, descending in a 

 steep, nearly straight line from first dorsal to tip of snout, the 

 ventral profile nearly horizontal, the depth 6 in length ; the head 

 large, its breadth equal to body depth, blunt, with projecting 

 jaw, and contained 3.6 times in head; the eyes close together, 

 high up, obliquely dorsolateral in position, nearly as long as 

 snout, 1^ times in snout; the flat interorbital contained 2.25 

 times in eye; the caudal peduncle contained 10 times in length, 

 a little less than 3 times in head, and 2 times in its own length ; 

 the plump naked cheeks crossed by five longitudinal rows of 

 minute papillae and warts on their lower half ; the lower margins 

 of preopercle and subopercle are fringed with fine papilla, and 

 on opercle is a similar row running diagonally backward and 

 downward ; the barbels on chin are very short, 2.5 times in eye ; 

 the anal papilla small, rounded, conical; in my specimen the 

 fins are too badly mutilated to show their original condition, 

 except the ventrals which reach beyond anal papilla almost to 

 origin of anal; the original description says, "spinous dorsal 

 with the second spine elongate, in males extending to or beyond 

 middle of soft dorsal; longest dorsal ray 1.6 in head; pectorals 

 1.1 in head; ventrals 1.35 in head; origin of anal fin midway 

 between tip of snout and base of caudal; base of anal 1.2 in 

 head, its longest ray 1.75 in head; caudal rounded, 1.1 in head." 



The color in alcohol brown, with five large, dark reddish brown 

 spots along midline of side, the last at base of caudal; three
