Depth three times and a half in the entire length: number of scales in the lateral line not exceeding fifty-one: anal with from twenty-two to twenty-four rays, C. Blicca, Block, Ichth. pl. 10.?

Rarely exceeding ten or twelve inches.
(Form). Not so deep as the last species; the back much less elevated: depth, at the commencement of the dorsal, contained three times and a half in the entire length: greatest thickness very little more than three times in the depth: dorsal line falling less obliquely, and continued in one regular slope to the end of the snout, without any depression at the nape: eyes relatively larger; the distance from them to the end of the snout not nearly equal to their diameter; the distance between them not equal to one and a half times their diameter: scales larger; the number in the lateral line about fifty or fifty-one, scarcely exceeding this last number: number in the depth fifteen; nine and a half being above, and five and a half below, the lateral line: anal shorter, with five or six fewer rays; dorsal and pectorals also with one or two rays less in number: in all other respects similar to the last.
D. 10 or 11; A. 22 to 24; C. 19, etc.; P. 15; V. 9.
(Colours). Back dusky, tinged with bluish green; sides of a silvery bluish white, with scarcely any of the golden yellow lustre observable in the last species: irides silvery: all the fins dusky, but sometimes very pale; pectorals and ventrals occasionally tinged with reddish.
This species, very distinct from the last, though closely resembling it, agrees in all respects with the C. Blicca of Bloch, excepting that 1 never saw the pectorals and ventrals of so deep a red as represented by that author. It is without doubt the same as the White Bream alluded to by Sheppard in the Linnsean Transactions*. It is of very common occurrence in the Cam, and is found in some parts of that river in which the C. Brama is not met with. It is known to the fishermen about Ely by the name of Bream Flat. It never attains to the size of the last species, rarely exceeding a pound in weight.
(6. Leuciscus, Klein). * Dorsal immediately above the ventrals.
