MACRURUS LEUCOPHZUS. 201 
Dark brownish, possibly reddish in life, the skin showing silver tints 
below the scales. ; 
The specimens from Station 3417 are hardly identical in variety with 
those from Station 3554; they are closely allied but differ in that the 
former (JZ. vagrans) is darker in color, and has less of the silver tint.

Closely allied to JZ. bodps, but distinguished by a wider snout, a wider 
interorbital space, and by the forward position of the ventrals. Form 
moderately elongate, body much compressed, and, as seen from the side, 
tapering rapidly but regularly to the slender whip-like caudal extremity ; 
depth near one sixth of the total length. Head about two ninths of the 
total, in length equal to twice its width or one and three fifths times its 
depth ; crown slightly convex ; suborbital ridge distinct but not very promi- 
nent, hardly reaching to a vertical from the hind border of the orbit. Snout 
as broad as long, length little more than the width of the interorbital space, 
about three fourths as long as the eye, very blunt at the end, as viewed 
from above, with a median and two lateral prominences, angle formed at 
the edges moderately pronounced, ascent from the mouth steep, distance 
of tip from maxillary or from the lateral angles hardly less than one half the 
orbital length. Orbit large, about one and one third times the length of 
the snout, one and two thirds times the interorbital width, or three tenths 
of the length of the head. Mouth comparatively small, maxillary extending 
below the eye not more than one fourth of the latter's diameter. Teeth 
small, in villiform bands. Barbel small, one fourth as Jong as the eye. 
Origin of first dorsal above the axil of the pectoral; base descending rapidly 
backward ; first ray short ; second ray with sharp close-set spinelets on the 
narrow forward edge, excavated or concave on the sides, prolonged in a 
slender filament to three fourths of the length of the head; basal length 
two thirds of the length of the eye. Second dorsal rudimentary toward 
its origin, weak and feebly developed backward. Anal better developed 
than the dorsal, originating immediately below the end of the base of the 
first dorsal, below the middle of the pectoral fin. Ventrals small, below the
