Total length, Om-58 ; to orbit, 0"W)39 ; to end of opercular bone, Om-105 ; to basis of pectoral (line), Om'll ; to 

 line of first dorsal, Om-117 ; to origin of second dorsal, Om-88; to origin of anal, Om-848 ; to end of second dorsal

Color in life bright red, with abroad purplish brown band from the end of the muzzle, through the orbit to the 

 caudal tin, occupying at first 1.5 rows of scales, and Anally the upper half of the caudal peduncle to the end of the 

 basis of the second dorsal. Six dark bands, formed by lines with intervals of ground color, extend from above the 

 lateral line to the dorsal fin, the posterior too transverse, the anterior more oblique. They are more distinct at the 

 base, where they form open spots. A large blotch of the same above the axilla,. The top of the head to the end of 

 the muzzle and the sides above the opercula are spotted with the same. In life, this color was brilliant— probably 

 brownish purple; but my attention having been withdrawn from the specimen, the action of spirits has injured it, 

 and I cannot recall the exact tint. 



From St. Kitts, from the collections of Benjamin II. Lightfoot. 



This is a huge and magnificent (ish, and apparently nearly affined to the O. chrysurus. It has a similarly grace- 

 ful form, but exceeds it in the length of the tail and slenderncss of the peduncle (the former is 4.83 times in the 

 length in the latter). It differs in many other details, and in color. Among the former may be mentioned the shorter 

 muzzle, smaller eye, high frontal keel, and more oblique mouth. The scales are less numerous, and the dorsal spines 

 more so. It differs in much the same way from the two allied species described by Pooy, 0. ambiguus and 0. de- 

 gam.
