SALMONID.E. 



The anal fin has its last ray underneath the posterior edge of 

 the adipose fin ; but the rays of the anal fin are also broken. 

 The formula of the fin rays is as follows : — 



D. 11 : P. 14 : V. 12 : A. 12 : C. 19. 



The scales are large and deciduous, the lateral line promi- 

 nent and nearly straight. Below the lateral line for the whole 

 length of the body two rows of the scales are silvery white, 

 forming a conspicuous elongated band, like that to be observed 

 in the Atherine,* the rest of the body and fins dull amber 

 colour, the gill covers silvery and iridescent. 



The figure of our well-known common Smelt is inserted as 

 a vignette to exhibit the comparative characters of the two 

 species.
