OBSERVATIONS ON FISHES. 



now in the Museum of the Cambridge Philosophical 

 Society. It measures 12 inches in length, with a 

 depth of 3 inches, 6J lines ; the greatest thickness 

 being 1 inch, 5 lines. It is distinguished from both 

 the two more common kinds of bream,* by its greater 

 thickness in proportion to its other measurements ; 

 and its much shorter anal fin, with fewer rays : and 

 from the yellow or carp bream by its much larger 

 scales, giving a smaller number both in the length 

 and depth. In this individual the number of scales 

 in the lateral line is about 50, and in the depth 16 ; 

 of these last 10| are above the lateral line, and 5J be- 

 low it. The fin-ray formula is as follows : D. 11, the 

 last double; A. 17, the last double; C. 19; P. 17; 

 V. 9. The colours of this fish, when fresh out of 

 the water, were as follows : upper part of the head 

 and back dark olivaceous brown, becoming lighter on 

 the sides, and passing into silvery on the belly ; a 

 faint golden hue, however, everywhere pervading: 

 dorsal, anal, and caudal fins dusky, tinged with pale 

 red ; pectorals and ventrals the same, but paler, or 

 with the reddish tint rather prevailing over the 

 dusky : cheeks and gill-covers silvery, inclining to 

 golden yellow : irides silvery.
