long as the body beneath, (-14,) and two and a third times as long as the 

 eleventh spine. The second anal spine is longest and nearly equals the fourth 

 dorsal one. The caudal forms more than a fifth (-22) of the length, and the 

 pectoral equals a fifth ( - 20.)

The color is greenish silvery, with faint oblique lines formed by the central 

 dots on the scales above the lateral line, and less oblique ones below. There 

 are two lateral bands ; one from the snout over the eye to the end of the dorsal, 

 and the other from the back of the eye to an oblong spot on the caudal pe- 

 duncle. The fins are nearly colorless. The preoperculum has a blackish 

 brown spot behind partly concealed. 



I dedicate this species to Mr. Scudder, already favorably known as an Ento- 

 mologist, and now engaged in the study of Ilcemulon and the allied genera. 



HyEMULON SEXFASCIATUS Gill. 



The greatest height is nearly equal to three-tenths ('29) of the extreme 

 length, and barely exceeds the head's length (=-28.) The diameter of the eye 

 nearly equals a third of the latter length as well as the length of the snout. 

 The supramaxillary bones reach behind nearly to the vertical from the front of 

 the pupil. The teeth of the external row in the upper jaw are strongly curved ; 

 those of the lower much less. The preoperculum is emarginated behind by the 

 production of its angle and is dentated. The dorsal fin is highest at its fourth 

 or longest spine, which nearly equals an eighth ( - 13) of the total length, and 

 its last spines are much abbreviated, the eleventh little exceeding a quarter of 

 the fourth (-63^.) The second anal spine is as long or longer than the fourth 

 dorsal. The caudal and pectoral fins are nearly equal, and contained about 

 four and a half times (22 23) in the total length.

The color is greyish-silver, with six broad bands on the body, the first between 

 the nape and dorsal fin ; the second under the first five spines; the fourth under 

 the last spines, and the sixth mostly behind the dorsal fin. 



ELemulon flaviguttatus Gill. 



The greatest height does not much exceed a quarter of the extreme length, 

 (.27,) of which the head forms a quarter. The eye's diameter equals a quarter of 

 the head's length, and is less than the length of the snout. The supramaxillary 

 bones end undsr the front of the pupils. The preoperculum is little emar- 

 ginated behind and is pectinated. The fourth dorsal spine is longest, and 

 equals a ninth ('11) of the total length ; the eleventh is as long or longer than 

 the twelfth or second dorsal one, and equals a twentieth (-5) of the length. 

 The second anal spine equals an eleventh of the length. The caudal fin forms 

 scarcely a fifth of the length, and the pectoral enters four times and a half in 

 the same.

The color is greyish, with sulphur-colored spots in the centre of each scale, 

 forming above the lateral line and below the spinous dorsal oblique lines tend- 

 ing upwards and backwards, and on the caudal peduncle longitudinal lines, 

 while under the lateral line they form longitudinal undulating lines.
