226 SALMONIA. 



ill-fed trout, but longer and thicker. 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 18, or, in 

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

 inches long by 8 in girth, weighed 16215 

 grains. Of the spines in the fins, the anal 

 has 9, the caudal 20, the ventral 9, the dor- 

 sal 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. 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 Professor Way- 

 ner 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 examined those of the Danube, Save, 

 Drave, Mur, and Izar : perhaps this is pecu- 

 liar to some stream in Bavaria — yet the 

 huchos in the collection at Munich have it
