D. |. A. A. l. lat. 25. 
Diagnosis. — Scales large. Snout slightly produced and a little longer than the 
diameter of the eye ; prseoperculum very indistinctly serrated ; dorsal and anal tins with 
the posterior margins rounded. The lateral line ascends from the suprascapula to the 
base of the fourth dorsal ray, runs along the base of the soft dorsal, and is lost towards 
the end of that tin ; the ocular band assumes the appearance of a dark blotch, extending 
in breadth nearly to angle of operculum, and in length to extremity of suboperculum. 
Colour. — Yellow, with darker lines, nearly vertical, following the series of scales. The 
soft portion of the dorsal, the anal, and the caudal have light margins and black intra- 
marginal lines. 
Description of the Specimen, — The body is rather elevated, its greatest height being- 
contained once and two-thirds in the total length. The upper profile descends abruptly, 
there being a long concavity in front of the eye ; the inferior profile is lower and less 
convex. The angle of the prseoperculum is nearly a right one, rounded and very 
indistinctly serrated. The spines of the dorsal are rather strong, increasing in length 
posteriorly, the last being the longest; the soft is slightly more elevated than the 
spinous portion, and is rounded posteriorly. The caudal is slightly convex. The soft por- 
tion of the anal is similar to that of the dorsal. The second anal spine is rather shorter 
than the third, which is about equal to the fourth of the dorsal. The scales are large, 
one of the largest being nearly as high as the diameter of the eye. The ventrals reach 
as far as the anal, and the first rays are slightly produced.
