riorly ; the maxilla reaches to below the middle of the orbit. The 

 greatest height of the preorbital equals 1 diameter of the eye. 

 Teeth villiform in the premaxillaries, with an external conically 

 enlarged row ; villiform in the lower jaw, on the vomer, palatines, 

 and tongue. Fins dorsal spines increase to the third, which is f 

 height of body; first few rays of second dorsal elevated, the 

 highest being |- height of body. Pectoral falciform, -j-^- of total 

 length. Anal similar to soft dorsal, its first few rays | as high as 

 body. Scales cover the cheeks, upper portion of opercles, and 

 behind the eyes, but none exist along the median longitudinal 

 crest on the head, which is well developed. They are also absent 

 from the chest in front of the ventral fins. They form a distinct 

 sheath to bases of soft dorsal and anal. Lateral line 90 scales ; in 

 its first half it forms a low, undulating arch, which terminates below 

 seventh dorsal ray ; height of arch f length of its base. The keeled 

 scales begin at commencement of straight portion of lateral line, 

 becoming largest below end of second dorsal, where they are ^ of 

 height of body. Colour greenish above, becoming a dull white on 

 the sides and below. No opercular spot.

Length of head 4g, height of body 3 in the total length. Eyes 

 with narrow posterior adipose lids, diameter 3| in length of head, 

 1 diam. from end of snout and also apart. Dorsal profile rather 

 more convex than that of abdomen. Lower jaw slightly the 

 longer ; the maxilla extends to beneath middle of eye. Central 

 longitudinal crest on the head well developed. Greatest height of 

 preorbital equals f diameter of eye. Lower edges of sub- and 

 interopercles more or less crenulated. Teeth villiform in the 

 premaxillaries, with an outer enlarged conical row ; a single row 

 in the lower jaw, with some of the teeth larger than the others ; 

 a triangular spot on the vomer, a band on the palatines, and also 

 along the middle of the tongue. Fins dorsal spines of moderate 

 strength, third longest, and ^ the height of the body or f that of 

 the anterior dorsal rays. Pectoral slightly longer than head. 

 Scales a few round the eye on the hind portion of the opercle, in 

 a patch in front of the ventral fins, but usually none anterior to 

 the base of the pectoral or below its anterior half ; the skin, how- 

 ever, is puckered and wrinkled into little pits, and occasionally the 

 scales extend halfway to between the ventral and anal fins. Lateral 

 line 90 to 95 scales; the arched portion terminates rather 

 abruptly below the third or fifth dorsal ray, the height of the arch 

 equals -fa the length of its base, whilst the length of its base equals f
