408 PISCES (OSSEI) MALACOPT. [CYPRINUS. 



(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 Linnaean Transactions*. It is of very common occur- 

 rence 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.

LENGTH. From twelve to fifteen inches. 



DESCRIPT. (Form.) Oval ; the back much elevated, and sharply 

 ridged: greatest depth at the commencement of the dorsal fin, about 

 one-third of the length, excluding caudal : greatest thickness not twice 

 and a half in the depth : dorsal line very convex, falling gradually to the 

 nape, whence the profile falls less obliquely and in nearly a straight 

 line, causing a slight depression at the part j ust mentioned : head con- 

 tained about four times and three-quarters in the whole length, caudal 

 excluded: mouth small: jaws equal: eyes moderate; the distance be- 

 tween equal to twice and a half their diameter : lateral line commencing 

 at the upper part of the opercle, and taking a descending course below 

 the middle, but not quite so low as two-thirds of the depth : head and 

 gill-covers smooth and naked: scales on the body broad, marked with 

 numerous very fine circular concentric striae, and with a few deeper and 

 more distinct lines radiating anteriorly and posteriorly ; number in the 

 lateral line forty-three; above it seven and a half; beneath three and 

 a half: dorsal commencing a very little behind the middle point between 

 the end of the snout and the base of the caudal ; its greatest height 

 equalling half the depth ; its length nearly the same ; first ray only one- 

 third the length of the second, which is longest ; third and succeeding 

 rays gradually decreasing; all except the first two branched; the last 

 two from one root: anal commencing a little beyond the termination 

 of the dorsal ; of a similar form ; second ray longest ; all the rays except 

 the first branched ; last two from one root : caudal deeply forked : pec- 

 torals rather more than three-fourths of the length of the head ; first ray
