Characteristics. Greenish above ; sides silvery. Dorsal and abdominal outlines convex. 

 Head very small. Length three to six inches. 



Description. Body much compressed, deep ; one-third of the total length, measured in a 

 line with the ventrals. Scales deciduous ; on the sides, large, orbicular, with concentric and 

 radiating stria, festooned on the edges. Lateral line deeply concave, following nearly the 

 abdominal outline. Head very small, scaleless ; upper jaw longest ; mouth opening upwards, 

 toothless. Eyes large. Nostrils double ; the posterior largest. Three flat branchial rays. 

 Abdominal outline very convex, thin, cultrate. 



The dorsal fin subquadrate, higher than long, highest in front ; the first is a short spine, 

 nearly hidden under the skin, about three lines in length ; the second and third successively 

 longer, and simple ; the fourth longest, and with the remainder branched, and gradually dimi- 

 nishing to the last. This fin is placed over the space between the ventral and anal, its last 

 ray being nearly over the first of the anal fin. Pectorals pointed, feeble, and with fifteen 

 rays. Ventrals long, pointed, and nearly equidistant between the snout and the end of the 

 body. Anal longer than high ; its margin excavated ; the first rays longest, the last higher 

 than the penultimate ray ; the first two rays simple. Caudal forked, with pointed lobes.

 metallic green behind the orbits. Irides pale yellowish ; beneath the orbits, pearly. Oper- 

 cles brilliant yellow, which disappears shortly after being taken from the water. Pectorals 

 and ventrals with faint orange tints. Sides of a brilliant lustrous white, which has suggested
