 and 8 between the anterior dorsal and anal rays. 



Depth of the body 5-33 in its length, and 1-4 in the head. Head 

 3"83 in the length of the body, its width 1'63 in its length. E^'e 3"67 in 

 the head, one-fifth longer than the snout, which is 45 in the head ; inter- 

 orbital space tliree-fifths of the eye-diameter. Caudal peduncle about 

 6ve-eighths longer than deep, its depth 8'5 in the body-length. Fourth 

 dorsal spine 1'77 in the head, pectoral a trifle shorter than the head. 

 Caudal 2'57 in the body-length. 



Head a little wider than deep, and wider than the body, its fronto- 

 occipital profile feebly rounded, that of the nape linear. Cheeks and 

 opercles covered with large cycloid scales. Cheeks with three horizontal 

 series of mucigerous pores ; parietal groove with two open pores, the 

 anterior very large and elliptical, the posterior rounded ; hinder limb of 

 pi'eoperculnm with three open pores. Eye large, longitudinally elliptical ; 

 interorbital region moderate, concave. Snout short and blunt, with a 

 rounded and stronglj^ acclivous profile. Jaws equal, the maxilla extending 

 to below the middle of the eye ; lower surface of the head with about 

 three pairs of short barbies inserted below the posterioi' half of the mouth. 

 Each jaw with a band of villiform teeth, the exterior row on the sides of 

 each premaxillary being a little enlarged ; an outer row of strong, curved, 

 subulate teeth anteriorl}'^ in each jaw, the posterior larger, and subcanini- 

 form on each side of the mandible. Tongue with the tip free and rounded. 

 Gill-openings not continued fcn-ward below, separated by a wide isthmus ; 

 exposed edge of shoulder-girdle entire. 



Body slender, compressed, the dorsal contoui' slightly more arched 

 than the ventral. It is covered with large ctenoid scales, which become 

 cycloid on the nape and breast. 



First dorsal originating well behind the pectoral base ; its spines are 

 low, and its outline rounded ; fourth spine longest, about as long as the 

 base of the fin and not reaching the second dorsal when depressed. Outer 

 border of second dorsal linear, the rays gradually increasing in length to 

 the penultimate ; this is much longer than the last, once and a half as long 

 as the fourth spine, and three-fourths as long as the base of the tin. Anal 

 commencing below the second and terminating below the ninth doi'sal 

 ray ; the penultimate ray is longest, but shorter than that of the dorsal, 

 1'8 in the basal length of the fin, which is 37 in the body-length. Pectoral 

 pointed, the middle rays longest, and extending to below the origin of the 

 second dorsal. Ventral inserted a little in advance of the pectoral base, 

 three-fourths as long as the pectorals, and not reaching the vent. Caudal 

 long and pointed.
