 this species, than in any I have seen. 



" Block, in his work on fishes, states that there 

 are black spots on all the fins, with the exception 

 of the anal, as a character of this fish : and Profes- 

 sor Wagner informs me he has seen huchos with 

 this peculiarity ; but, as 1 said before, I never saw 

 any fish with spotted fins, yet I have examined 

 those of the Danube, Save, Drave, Mur and Izar ; 

 perhaps this is peculiar to some stream in Bava- 

 ria, yet the huchos in the collection at Munich 

 have it not. The hucho is found in most rivers, 

 tributary to the Danube, — in the Save and Lay- 

 bach rivers, always ; yet the general opinion is 

 that they run from the Danube, twice a year, in 

 spring and autumn.

 running streams, for they had the winter leech, or 

 louse of the trout upon them; and T have seen
