Greatest width on head behind eye, 2^ in greatest depth. Yentral 

 outline well arched to beginning of caudal peduncle, thence slightly 

 concave to caudal fin, somewhat more curved than dorsal; profile nearly 

 straight from end of snout to occiput, thence gently curved to caudal 

 peduncle, which is little concave. 



Snout rather ijoiuted, very short, not two-thirds of orbital diameter. 

 Eye large, 24 in head; interorbital width slightly less than diameter of 

 eye. Mouth moderate, maxillary reaching almost to pupil, 2f in head. 

 Teeth in villiform bands, the teeth on upper jaw higher and the band 

 wider in front than on the sides ; the band on mandible similar but nar- 

 rower; minute teeth on palatines and pterygoids, and in a /^-shaped 

 band on vomer. 



Preopercle finely pectinate on whole length of lower limb, becoming- 

 coarser at the angle, extending only on lower third of upright limb, 

 which is scarcely oblique. The inferior of the two opercular spines 

 longer and narrower than the superior one. Preorbital narrow, notched, 

 the lobe in front of the notch serrate. Gill-rakers slender, long, 2 in 

 eye, about 2S on lower part of gill-arch. 



Scales moderate, minute ones extending upon caudal; a well devel- 

 oped basal sheath of small scales on dorsal and anal pectorals, w'ith 

 small scales on their base. 



First doi'sal spiue shortest, 2}^ in eye, second 1| in eye, third spinal 

 three times height of first, fourth and fifth higliest. If in head, thence 

 decreasing to ninth, which is 4 in head, the tenth spine 3 in head; soft 

 part of dorsal obliquely truncate, its first ray 2^ in head, the last 4^ in 

 head. Anal somewhat concave, its soft portion longer than articulate 

 part of dorsal, and the median rays lower than those of soft dorsal; 

 first anal spine If in third, second stronger and little shorter than third,
