SCOMBEE ANTAllCTICUS. 
{The Mackerel.) 
Height of body five and a-quarter times in its total length ; 
head four and a-quarter times in the same ; orbit five and a-half 
times in the length of head. The first dorsal has eleven spines, 
the longest of which is the second, the last being very small and 
difficult to see ; the second dorsal has one spine and eleven rays, 
of which the first is the longest, and the others go on decreasing, 
the four last being about equal amongst themselves and also to 
the spine ; these cover five jpinnulw. The caudal has fifteen long 
rays and numerous shorter ones on each side ; the lower pinnuloe 
are also five in number. The anal has the same form as the dorsal, 
and shows one spine and eleven rays ; the pectoral has twenty rays. 
The membrane that covers, on each side, a part of the eye does 
not hide more than one-third of it. On the living specimen, the 
lower portion of the prsBoperculum appears entirely striated ; but 
on the dried one it is smooth, and the interior edge seems 
to bear the marks of strong denticulations ; the upper part of 
the prseoperculum is covered with scales, and others, much larger 
and of a very elongate form, cover a space below the eye. The 
teeth are small, rather hooked, equal, and disposed on a line ; at 
the upper jaw, they are only visible in front, and, after decreasing 
in size, disappear entirely on the sides ; on the lower jaw, they 
are much more numerous and extend backwards ; on each of the 
palatines there is also a line of numerous teeth, rather longer, 
more slender, and more arched than those of the jaws. There 
is no air-bladder. 
The colour is of a dark greenish blue on the upper parts, and 
of a silvery white on the lower ones ; the back is covered with 
black waving lines, very irregular, but having generally a 
transverse disposition. On the sides of the body is a longitudinal 
series of larger and rounded ones ; all the lower parts are covered 
with little black dots, very numerous, and irregularly disposed. 
There are yellow tinges behind the eye and on the sides of the 
body, and the lower part of the sides of the head shows five
