Habitat, King George’s Sound, New Holland. 
Cuvier and Valenciennes have noticed several variations of form occurring in 
different specimens of the C. trachurus, from different seas, which they have not 
ventured to raise to the rank of species. That the one here described is entitled, 
however, to this distinction, I can hardly entertain a doubt. The suddenness of 
the bend in the lateral line, and the more backward point at which the bend 
commences ; the larger number of laminz which protect it; and also the larger 
number of rays in the second dorsal and anal; all seem to indicate a specific 
difference. Whether it be identical with any of the varieties noticed by them is 
uncertain ; but it seems to be distinct from the only one they speak of as having 
been received from New Holland, in which the number of lamine did not exceed 
seventy-three. I have called it declivis, in reference to the character of the lateral 
line above alluded to. It was obtained by Mr. Darwin in Princess Royal 
Harbour, in King George’s Sound.

Form.—Thicker and deeper in the body than the C. trachurus. The greatest depth a little less 
than one-fourth of the entire length; the thickness exceeding (but by a very little) half the 
depth. Head large; its length a little more than one-fourth of the entire length ; its height or 
depth, taken in a line forming a tangent to the posterior part of the orbit, less than its own 
length by two-sevenths. Eyes large; their diameter very nearly one-third the length of the 
head ; partially covered at the sides by two fatty membranous veils, as in several other species. 
The ventral line of the body is rather more curved than the dorsal, and the upper profile in 
like manner a little more approaching to rectilineal than the lower. The lower jaw a little the 
longer, and ascending to meet the upper. Maxillary reaching not quite to beneath the middle 
of the eye; its extremity truncated in the form of an arc, with the curvature inwards. In each 
jaw a single row of very fine, minute, closely set teeth; two small patches on the anterior 
extremity of the vomer, a band on each palatine, and one on the tongue, all closely shorn 
velutine. Suborbital, on each side of the extremity of the snout, marked with several nearly 
parallel dark-coloured veins, Preopercle with the angle very much rounded ; the limb broad,
