2.$0 TRAVELS IN UPPER.

The pectoral fins have ten rays; the dofsal fin
has twenty-four ; the anal, thirty-eight; and the
ventral, six. The other particulars of it?: figure
are so well expressed in the plate, that it is un-
necessary to mention them.

The top and upper half of the sides of the head
are of a shining blackish colour, with little gray
spots not very conspicuous : the rest of the head
is blue, tinged with red, and speckled with black.
The eyes are of a blueisb gray. The back is
blackish. This sort of dubious colour grows
lighter on the sides of the body, and becomes
gray toward the belly, with duskier tints in some
places. The pectoral fins are gray: the ventral
are the same at the base, and blackish at the
extremity. All the other fins are of the latter
obscure colour.

The hersS never grows very large. The whole
length of that from which my figure and descrip-
tion were taken did not exceed six inches and a
half; and though several individuals of the species
attain greater dimensions, none are much larger.
It has a triangular heart, a gall-bladder, the
intestinal tube but little convoluted, with a long
appendicule a little below the stomach, and a
very large air-bladder of a silvery hue.
