 all the varieties of Salmo fario, whose teeth 

 serve as one of its main distinguishing features. 

 There are 26 to 30 rows of scales above and 

 21 below the lateral line, and IS in an oblique 

 direction, from behind the adipose fin forward 

 to the lateral line. 



The other variety is much smaller, and 

 inhabits the Scotch and Irish rivers, and some 

 of those in the northern counties of England, 

 both forms being found in Shropshire. The 

 smaller variety is called by Giinther the 

 Salmo fario gaimardi. It has 59 to 60 

 vertebrae, and seldom exceeds 15 inches in 

 length. It is the small burn trout of the 

 Highland streams, rarely weighing more than 

 a pound to a pound and a quarter. It has not 

 yet been introduced into the Southern Hemi- 

 sphere, but the Council of the Melbourne 

 Acclimatization Society has taken steps to

 ment of the ova. It is likely that this fish, 

 from its smaller size, would suit Australian 

 streams better than the larger variety ; but as,

 doubtful whether it may stand the climate so
