SALMON-TROUT. 41 



dark as the colour of the back ; the pectoral fin rather small 

 and bluish white ; the ventral fins white, arising in a vertical 

 line under the middle of the dorsal fin ; the anal fin white, 

 the base of the fin one-third shorter than the longest of its 

 fin-rays. When the Salmon-Trout is placed by the side of 

 a Salmon, it is, in comparison, darker in colour in the body, 

 but lighter in the colour of the fins. 



The Phinock or Hirling of the North, the Salmo albus 

 of Dr. Fleming, is perhaps distinct from the Salmon-Trout 

 just described ; but the specimens of it which I have received 

 so exactly resemble the young of the Salmon-Trout in its 

 first year, that I am unable to point out any sufficiently 

 distinguishing specific character ; it is therefore omitted as 

 a species, in the hope that it will be hereafter described and 

 figured by some naturalist who has better opportunities, and 

 more materials for proving its specific distinction.
