164 TELEOSTEI. ACANTHOPTEKYGII. 



Cleft of mouth oblique ; rnaxilla reaching to below middle of eye. 

 Greatest width of preorbital | in young to | in adult of dia- 

 meter of orbit. Preopercle with some rather strong denticulatious 

 along both limbs; which become almost imperceptible in the adult. 

 Teeth in a narrow villiform band, or in two rows in the premaxil- 

 laries, the outer slightly enlarged ; a single row in lower jaw, 

 except at its anterior portion, where they are largest, and have a 

 few villiform ones behind them ; a triangular patch on the vomer, 

 and a band along the palatines and on the tongue. Fins dorsal 

 spines low, the longest -fa to | height of body ; second dorsal 

 very much elevated anteriorly, where its rays equal from f to as 

 long as the height of the body. Pectoral as long as the head or 

 longer. Ventral almost reaches the preanal spines. Anterior 

 rays of anal elongate and equal to f of height of body. Caudal 

 deeply forked. Scales along the upper and hind edge of the 

 eyes, on the cheeks and body, except on the chest as high' as the 

 pectoral fin, which is scaleless in the young, but in the adult the 

 scaleless area is confined to the chest anterior to ventral fin, and 

 about half the distance to the base of the pectoral. A low sheath 

 to second dorsal and anal fins. Lateral line about 105 scales, 

 at first plate-like and rounded ; the line goes directly backwards 

 and commences to descend below the commencement of the second 

 dorsal, becoming straight again beneath the ninth ray ; the height 

 of the arch equals f of its length ; the keeled scales" extend along 

 the whole of the straight portion, the widest about -^ height of 

 body. Colour golden in the young, with vertical bluish bands, 

 which soon fade after death ; the adults are more olive, becoming 

 dull white beneath. No opercular spot. Fins yellow, stained at 

 their edges, the stain due to innumerable fine dots; caudal 

 orange, with its posterior half black, a light tip to both lobes.

 Length of head nearly 4, height of body 3| in the total length. 

 %* without any adipose lids ; diameter 5 in length of head, 

 nearly 2 diam. from end of snout, and 1| apart. Dorsal profile 

 slightly more convex than abdominal ; interorbital crest well deve- 

 loped. Lower jaw very slightly the longer, mouth very slightly 

 oblique ; maxilla reaches to below front edge of eye. Lower limb 

 )t preopercle, also sub- and interopercles crenulated. Teeth m 

 numerous villiform rows in both jaws, a triangular patch on vomer, 

 a long narrow band on palatines, none on tongue. Mm third 

 lorsal spine longest, f height of body, and rather above 1 as high as 

 anterior dorsal rays; second dorsal elevated in front. Pectoral
