less numerous round spots, of a blood-red colour, most intense on the sides. 

 There are two large pale spots between the eyes and pre-operculum, and white 

 spots mark the under side of the head, especially the lower jaw. The base of 

 the dorsal fin is marked with black spots, but all the other fins are brown ; 

 the brown passes into white at the tip of the ventral, and into yellow at the 

 edge of the pectoral. The iris is a coppery-brown. The colour of the flesh is 

 sometimes reddish, sometimes white, from which we can infer only that the 

 colour may vary with food. 



This fish does not migrate, and is known only from the rivers of Dalmatia, 

 where it is termed by the inhabitants Pastrova. Fine specimens in the lliver 

 Narenta reach a length of forty-four inches, though the common length is 

 about two feet. 



Steindachner has regarded this species as a variety of the Common Trout, 

 S. ausonii.

This Trout is a somewhat obscure species, Heckel and Kner apparently 

 not intending quite the same fish as Valenciennes. They state that it is spread 

 over Northern Europe, all over Russia, and appears at Teschen, in Silesia, but

is not recognised by Russian, German, or Scandinavian ichthyologists ; and 

 Dr. Giinther remarks that the only point in common between the fishes of the 

 Austrian and French naturalists is that the scales are more conspicuous than 

 usual, a criticism which the published descriptions do not quite justify. 

 Since Valenciennes gave no locality for his specimen, and, so far as is known,
