107. Chsetodon melanopoma, sp. n. Plate VI. fig. 2. [129.] 



D. g. A. J. 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 fins 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 fin; 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.
