when that fin is depressed the first ray is short, the second 

 ray the longest, the last double ; the fleshy portion of the 

 tail is long and slender, the caudal rays are also long and 

 deeply forked ; all the fins a little longer than those of the 

 Dace. 



The scales are of moderate size, rather larger than those of 

 the Dace, the diameter across the line of the tube greater, 

 and the radiating lines less numerous, as the vignette repre- 

 senting a scale from the same part of the lateral line in two 

 fishes of equal size will show : the number of scales of the 

 series forming the lateral line forty-eight, those in an oblique 

 line up to the base of the dorsal fin eight, and downwards to 

 the origin of the ventral fins four ; the lateral line descends 

 from the upper edge of the operculum by a gentle curve to 

 the middle of the body, and thence to the centre of the tail 

 in a straight line. The fin-rays in number are 



D. 9 : P. 17 : V. 10 : A. 11 : C. 19. 



The Graining has the top of the head, the back, and upper 

 part of the sides of a pale drab colour, tinged with bluish 

 red, separated from the lighter-coloured inferior parts by a 

 well-defined boundary line ; the irides are yellowish white ; 

 cheeks and gill-covers shining silvery white, tinged with yel- 

 low ; all the fins pale yellowish white.
