228 SALMON 1 A. [ninth pay. 



He has larger teeth, more spines in the pectoral fin, a 

 thicker skin, a silvery belly, and dark spots only on 

 the back and sides, — I have never seen any on the 

 fins. The ratio of his length to his girth is as 8 to 1 S, 

 or, in well-fed fish, as 9 to 20 ; and a fish, 18 inches 

 long by 8 in girth, weighed 16,215 grains. Another, 

 2 feet long, 11 inches in girth, and 3 inches thick, 

 weighed 41bs. 2|oz. Another, 26 inches long, 

 weighed 51bs. 5oz. Of the spines in the fins, the 

 anal has 9, the caudal 20, the ventral 9, the dorsal 

 12, the pectoral 17 : having numbered the spines 

 in many, I give this as correct. The fleshy fin 

 belonging to the genus is, I think, larger in this 

 species than in any I have seen. Bloch, in his work on 

 fishes, states that there are black spots on all ihe fins, 

 with the exception of the anal, as a character of this 

 fish : and Professor Wagner informs me he has seen 

 huchos with this peculiarity ; but, as I said before, I 

 never saw any fish with spotted fins, — yet I have exa- 

 mined those of the Danube, Save, Drave, Mur, and 

 Isar : perhaps this is peculiar to some stream in 

 Bavaria — 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 Laybach 

 rivers always ; yet the general opinion is that they run 

 from the Danube twice a year, in spring and autumn. 

 I can answer for their migration in spring, having
