The lengtli of tlie head compared to that of the body alone 

 is as one to three ; the head larger, and the fleshy portion 

 of the tail deeper, than in a Carp-Bream of the same size, 

 and the fish in consequence has a more bulky and less neat 

 appearance : the diameter of the eye compared to the length 

 of the head is as two to six, occupying a full third ; it is 

 therefore larger than in the other Bream, leaving the space 

 between the eye and the edge of the preoperculum narrower 

 in comparison, and affecting the proportions of the various 

 parts of the head : the irides are silvery white tinged with 

 pink, in the other fish yellow : the nape without any de- 

 pression, ihe curve of the back uniform : the scales of the 

 body larger ; the vignette shows the comparative differences 

 both in structure and size in two scales, one from the lateral 

 line of each of two fish of very nearly the same length ; the 

 colour of the scales bluish white : the lateral line not quite 

 so low down on the body as in the Carp-Bream ; the number 

 of scales forming the lateral line about fifty ; the number 

 up the side fifteen, of which nine are above the punctured 

 scale forming the line itself, and five below it : the character 

 and relative position of the fins not very dissimilar, except 

 that the dorsal fin in the White Bream, the subject of the 

 present article, begins rather nearer the head ; but the num- 

 ber of the rays in the pectoral and anal fins differ consider- 

 ably, the pectoral fin of the White Bream having three 

 rays, and the anal fin five rays, less in number than the 

 same fins in the Carp-Bream. The fin-rays in number 

 are —

The general colour of the sides is silvery bluish white, 

 without any of the yellow golden lustre observable in the 

 last species ; the irides silvery white, tinged with pink,
