account of it to have much resemblance to one of the preceding two, but it differs from them 

 both in having a gibbous forehead, in the lateral line traversing the body at mid-height and 

 in the greater number of its anal rays.

A specimen was presented by Mr. Reeves to the British Museum. Having omitted to de- 

 scribe the colouring in the ' Ichthyology of the Sulphur,' I may here state that in Mr. Reeves's 

 drawing the top of the head is represented of a deep olive-green colour, and that a fainter 

 tint of the same extends along the back, but is glossed with much brassy lustre. Immediately 

 above the lateral line there is a dilute tinge of crimson, and all the under parts are pearl-gray 

 and brightly silvery. The cheeks are silvery. The under lip deep rose-red, and the gill- 

 cover and membrane are washed with the same. The rays of all the fins are more or less 

 brightly crimson, and the membranes, which vary from dark greenish-gray to blackish-gray, 

 are glossed with crimson on the under fins. This tint is richest on the pectorals, and there 

 are also orange colours between the rays of these fins. 



Since this fish was figured and described in the ' Ichthyology of the Voyage of the Sulphur' 

 under the specific name given to it by Mr. Gray, I have ascertained by consulting the 4 Icones 

 Piscium 24 a pictore Sinensi Cantoni eleganter pictae,' that it is the L. molitrix of M. Valen- 

 ciennes. The drawing in the work just quoted measures 11 inches.

 nese name, Tsingyu, " Eminent fish" (Reeves). Genus Aspius, Agassiz. 

 Mr. Reeves has deposited a specimen of this fish also in the British Museum. The brassy 

 hue of the scales of this and the preceding species draws attention to the names cupreus and 

 eeneus given by M. Valenciennes to two Chinese Leucisci, but the few particulars of form 

 which he has recorded do not correspond, and had the drawings he comments upon repre- 

 sented either hypophthalmus or nobilis, he could not have failed to remark the unusual de- 

 pression of the eyes into the curve of the preoperculum. In fact both extremities of the sub- 

 orbitar chain rise above the level of the eye, as they do also, though in a less degree, in L. 

 jesella and some other species.

Leuciscus rosetta, C. et V. xvi. p. 356. Length of figure 10^ inches, the 

 head one-third of the length. 



L. nobilis is the only Leuciscus represented by Mr. Reeves's drawings which has so large a 

 head as rosetta ; and in nobilis the head equals the third of the length only when the caudal 

 is excluded. There is no drawing of this species among the ' Icones Piscium 24 a pictore 

 Sinensi,' &c.

Leuciscus recurviceps, Richardson. Icon. Reeves, 149 ; Hardw. Malac.

head" (Reeves). Length of figure from mouth 15 inches. Height of body 



3*3. Length of head 3. Genus Aspius, Agassiz. 



This fish is remarkable for the face being inclined upwards by a sudden curvature over the 

 temples like the profile of a pug-dog. The nape rises in a short arc, but the dorsal line is 

 only slightly convex, while the belly is considerably more curved, and the tail behind the anal 

 is slender. The head, excluding the lower jaw, is one-fifth of the length of the fish ; and the 

 height of the body is a little more. The drawing represents a convex keel between the ven- 

 trals and anus. The cleft of the mouth is vertical, with a curve towards its angle ; and the 

 lower jaw, which forms the anterior end of the head, is dilated and apparently naked, like 

 that of Aspius mento and maxillaris. The large eye is equal in diameter to a fourth part of 

 the length of the head, and is situated one diameter behind the mouth. The lateral line is 

 decurved at its commencement, and makes a sudden short bend downwards under the dorsal, 

 after which it ascends very gently in a straight line till it has passed some way beyond the
