Spec. Char. —Body rather short, sub-fusiform iu profile; back slightly arched. Head constituting the fifth of the entire 
length. Diameter of eye entering nearly four times in the length of the side of the head. Gape of the mouth oblique. Posterior 
extremity of maxillar bone extending to a vertical line drawn behind the nostrils. Anterior margin of dorsal fin nearer the 
insertion of the caudal than the tip of the snout. Origin of ventrals situated somewhat in advance of the dorsal. Pectorals 
slender and elongated. Yellowish brown, ligher beneath than above; middle of flanks metallic white. Pins unicolor.

By its general form and appearance this species establishes the transition between the deep 
and slender species. The head forms about the fifth, and the depth the fourth, of the total length. 
The dorsal fin is higher, and the anal deeper than long ; the anterior margin of the anal is 
nearer the tip of the lower lobe of the caudal than the extremity of the snout. The tips of the 
ventrals approximate the vent; hut the extremities of the pectorals do not reach the origin 
of the ventrals.

The scales are moderate sized, sub-elliptical in their outline, though rather truncated ante¬ 
riorly. The lateral line describes a gentle curve below the middle of the flanks. 
The color is yellowish brown above, the middle of the flanks reflecting a metallic white tint, 
whilst the belly is light yellow. The fins being unicolor, of a light yellowish tint.
