The caudal is emarginate, the external rays being only 1^ times as long 

 as the middle rays. The length of the superior external rays (.21G), 

 measured from the origin of the middle rays, equals IJ times the length 

 of the spinous dorsal base. 



The distance of the pectoral from the snout (.32) very slightly exceeds 

 the length of the anal base. The length of the pectoral of the right 

 side (.244) equals twice that of the snout. The pectoral of the left side 

 is probably imperfect; its length (.216) being equal to that of the supe- 

 rior external caudal rays. The right pectoral can be made to reach the 

 vent: in its natural position it extends to the perpendicular let fall from 

 the 4th ray of tlie 2d dorsal. 



The distance of the ventral from the snout (.347) equals 4 times the 

 least height of the tail. The length of the ventral (.183) equals twice 

 that of the 3d dorsal spine, and it extends to a point under the third 

 dorsal ray. The distance from the tip of the ventral to the vent equals 

 half the length of the middle caudal rays. The vent is under the inter- 

 val between the fourth and fifth dorsal rays. 



Radial formula.— B. VI; D. VII, 15; A. Ill, 13; 0. 18; P. II, 15; V, 

 I, 5; L. Lat. 03; L. Trans. 8+30. 



Color. — The operculum, preoperculum, upper surface of head, and ma- 

 jor portion of the body, have numerous greenish-yellow spots, the largest 

 of which are about ^ as long as the eye. Upon the caudal rays are about 

 eight stripes of the same color, some of them connected by cross blotches. 

 The upper part of the body has a violaceous tint, and the lower parts are 

 whitish, with some areas of yellow. The anal and ventral fins are 

 whitish. The pectorals have the tint of the upper surface of the body, 

 with some yellow^ ui)on their posterior surfiices. The soft dorsal has an 

 upper broad band of violaceous, and a narrow basal portion of whitish. 

 Many of the rays have upon them a yellow stripe; there are some spots 

 of the same color, especially upon the anterior portion of the fin. 



XoTE. — In the table of measurements, the unit of comparison is the 

 length to the origin of the middle caudal rays.
