head forms a quarter of the length, and its height at the nape equals a sixth 

 of same ; the snout is gradually decurved, and its length equals an eleventh 

 (09) of the total ; the height of the preorbital bone at the angle of the mouth 

 equals two-thirds (06) the length of the snout. The diameter of the eye 

 nearly equals a third (-08) of the head's length. The barbels extend nearly 

 to the vertical of the preoperculum. The teeth are rather strong ; in the upper 

 jaw uniserial, in the lower biserial in front. The caudal fin forms more than a 

 fifth (-22) of the total length, and the pectoral fin equals a sixth of the same.

The color is a bright pink or rose, with a broad red band extending from 

 the eye to the caudal fin, and suffusing the caudal itself. 



This species is as closely related to the Upeneus flaviviltatus (Poey) of the 

 Caribbean Sea as any other species, but differs widely in dentition as well in 

 the size of the scales, &c. 



Three specimens, nearly four inches long, are in the collection.

Subfamily SCI^NDLE (Bon.) Gill. 



Umbrina dorsalis Gill. 



The greatest height equals three-tenths (-30) of the extreme length. The 



head forms a quarter (-25) of the length and declines nearly in a straight line ; 



at the vertical of the preopercular angle its height equals -22, and at the pupil 



17 of the total length. The diameter of the eye equals a third of the head's 



length, and that of the snout a quarter. The barbel is very short and thick. 



The preopercular teeth behind are small and distant. 



The spinous dorsal is convex; the second anal spine strong and equal to a tenth 

 of the total length. The caudal fin is subtruncated, and forms a fifth of the 

 length. The pectoral enters six times and two-thirds (*15) and ventral five 

 times and a half ("18) in the same length.

 The color is silvery, tinged on the back with rose. The upper half of the 

 dorsal fins are sometimes punctulated with black. 



Umbrina xanti Gill, 

 The height is rather less than a quarter (-23) of the total length*. The length 

 of the head equals the greatest height, and is nearly a quarter greater than the 

 height at the preopercular angle (=-18) and twice that at the pupil (-12). The 

 diameter of the orbit nearly equals a third (-07) of the head's length, while 

 the snout enters about four times and a half (-05) in the same. The barbel is 

 short and moderately thick. The teeth of the preoperculum behind small and 

 distant. The spinous dorsal is rather angular; the second anal spine not 

 robust and equalling an eleventh (09) of the total length. The caudal enters 

 five times and a half in the length ; and its margin is nearly truncated. The 

 pectoral fin rather exceeds an eighth (-13) and the ventral a seventh (-15) of 

 the length.
