1| in the length of the snout. There is a slight protuberance before 

 the upper anterior angle of the eye ; the upper maxillary reaches to 

 the vertical from the anterior nosti-il. Canine and molar teeth mo- 

 derate. Dorsal spines rather feeble ; the fourth is the longest, rather 

 shorter than the highest ray, and 2| in the length of the head. 

 Caudalis slightly emarginate. Greenish olive, with an oblong lateral 

 blotch of blackish colour below the lateral line and below the middle 

 of the dorsal fin.

The height of the body equals the length of the head, and is 3| 

 in the total. The snout is rather elongate and pointed ; the length 

 of the diameter of the eyes is rather more than the width of the 

 distance between them, and one-half the length of the snout ; the 

 upper maxillary bone does not reach to the vertical from the anterior 

 nostril. Canine and molar teeth rather small. Dorsal spines mode- 

 rate, the fourth nearly equal to the longest ray, and one-third of the 

 length of the head. Caudalis emarginate. Uniform olive ; in life 

 with an indistinct shining yellowish longitudinal streak.

The height of the body is four times in the total length, the length 

 of the head .3^, The diameter of the eyes is 3^ in the latter, and more 

 than the distance between them. The snout is longer than the eye, 

 and the upper maxiUary bone does not reach to the vertical from the 

 anterior margin of the orbit. The posterior teeth are molars ; ca- 

 nines moderate. The fifth dorsal ^pine longest, one-third shorter 

 than the height of the body, and shorter than the rays. Caudalis 

 forked, with pointed lobes. Olive, with four or five orange-coloured 

 or red longitudinal bands ; fins immaculate, reddish yellow, the spi- 

 nous dorsal brown-edged. {Bl.)
