PLATE 9, PIG. 3 



Dorsal VI, 1-11 or 12; anal I, 11; there are 25 to 27 scales 

 in a longitudinal series and 10 in a transverse series; 10 scales 

 before the first dorsal. 



The elongate oblong body strongly compressed laterally, the 

 dorsal profile more or less gently arched, the greatest depth 

 4 to 4.6 in length ; the head of moderate size, broader than body 

 but deeper than wide, with convex anterior profile and nar- 

 rowed, almost ridgelike nape, its length about 3.5 times (3.46 

 to 3.7) in that of head and trunk together; the convex snout 

 short, blunt, 3 to 3.4 times in head ; the eyes high up, close to- 

 gether, dorsolateral in position, their length equal to or slightly 

 less than that of snout; the interorbital narrow, about 3.5 times 

 in eye; the mouth small, terminal, oblique, the jaws equal, the 

 posterior angle of maxillary extending or almost extending to 

 a point beneath front margin of eye ; in the upper jaw are two 

 rows of curved, depressible teeth, preceded by one or two pairs 

 of long, slender, inward-curved caniniform teeth on either side 

 of median line of jaw; in lower jaw are two rows of teeth, the 

 outer one of ten or twelve large, widely spaced teeth, termi- 

 nating in a pair of backward-curved canines ; the caudal pedun- 

 cle wide, 2.3 to 2.4 in head ; the first dorsal low, the tips of the 

 spines filamentous but not elongated, reaching second or third 

 ray of second dorsal when depressed, the longest 1.14 to 1.4 

 times in depth and 1.4 to 1.7 in head; the second dorsal and 

 anal approximately equal in height and equal to or higher 

 than first dorsal, the posterior rays reaching base of caudal when 

 depressed, 1.1 to 1.25 in depth and 1.3 to 1.5 in head; the caudal 

 truncate or with rounded corners, equal to or a trifle more or less 

 than head, 3 to 3.75 times in length; the pectoral and ventral 

 approximately equal in length, equal to or a trifle less than head 

 in length, and reaching to or beyond the small pointed anal 

 papilla or reaching anal. 



The body covered with loosely attached, large, ctenoid scales 

 which extend forward to eyes; there are four rows of large 

 scales on preopercles and three on opercle ; the base of pectoral
