Tatok-layam, name at Puerto Princesa, Palawan. 



Dorsal VI, 1-8 or 9; anal I, 7 or 8; there are 27 scales in a 

 longitudinal series and 9 or 10 in a transverse series. 



The body strongly compressed laterally, with thick heavy head 

 equal to depth and 2.7 to 3 times in length; the short snout a 

 little less than eye, 3.5 to 4 in head; the eyes high up, dorsolat- 

 eral, 3 x or a little less than 3 times in head; the interorbital 

 space about 3 times in eye ; the body covered with ctenoid scales, 

 the head, nape, breast, and pectoral base naked ; the large mouth 

 very oblique, almost vertical, with strongly projecting lower 

 jaw; the posterior angle of maxillary is beneath front margin 

 of eye or may extend a little beyond it; the teeth in upper jaw 

 in four rows, an outer row of enlarged teeth curved inward, 

 and three rows of minute teeth, with a group of larger teeth 

 in center behind middle of front row ; in the lower jaw there is 

 a band of three (four?) rows of very small teeth, followed by 

 an inner row of enlarged erect needlelike teeth ; the dorsals are 

 separated, the second, third, and fourth spines of first dorsal 

 elongated and threadlike, the longest spine 3 times in length, 

 equal to or a little less than head (according to Giinther's figure 

 it may equal half the total length) ; the second dorsal and anal 

 similar in shape, the posterior rays longest and reaching caudal 

 when depressed, about f depth; the caudal broadly rounded, 

 shorter than head ; the broad pectoral shorter than caudal ; the 

 long slender ventrals reach anal papilla. 



The color of alcoholic specimens brown, with seven or more 

 conspicuous, broad, pale crossbands edged with dark brown on 

 anterior half of body ; the fins all uniformly colored except first 

 dorsal, which is crossbarred by rows of red spots. 



A specimen sketched from life by T. S. Espinosa, was dark 

 wine red, with whitish crossbands on anterior half ; the fins paler 

 than body, and all, except ventral, crossbarred with many rows 

 of red spots.
