Diagnosis. — Snout very slightly produced, and rather shorter than the diameter of 

 the eye; praeoperculum slightly denticulated. Dorsal and anal fins rounded posteriorly. 

 The black ocular band is half the diameter of the eye, and is continued over the chest. 

 A large black blotch on the side below the four posterior spines and the three first rays 

 of the dorsal ; two-thirds of this blotch is below the lateral line. Caudal with a broad 

 white margin ; the remainder of the body and fins yellow, with narrow darker longitu- 

 dinal lines following the series of scales. 



Description of the specimen. — Body oval, its greatest height being half of the total 

 length. The upper profile descends abruptly from the origin of the dorsal ; the lower 

 profile is very similar to the upper. The snout is short, obtuse, rather less than the 

 diameter of the eye, or than the interorbital space. The angle of the praeoperculum is 

 nearly a right one, rounded and slightly denticulated. The spines of the dorsal are 

 moderately strong ; the fifth and sixth are the longest ; thence they decrease slightly in 

 length, the last being equal to the fourth. The soft portion is lower than the spinous, and 

 is rounded posteriorly. The caudal is convex ; the soft portion of the anal corresponds to 

 that of the dorsal. The second anal spine is longest and strongest, but shorter than the 

 longest of the dorsal. The pectorals and ventrals do not reach as far as the vent. Scales 

 moderate ; one of the largest covers half the eye. — Length b\ inches.
