The S;ilni()ii, with it.s imiltitii(K' <if naiiR'S, occurs 

 witliin the S<';iii(liii;i\ i;ui hiiimi in iiuiuerous varieties, 

 both (if I'orm iiiid cohnir, the extremes being very easy 

 to (listiiigiiisli liy well-marked cliaraeters, but connected 

 by intermediate forms in a manner that compels us, 

 after a comparative study, to comprehend them under 

 one specific designation. The most clearly distinct 

 varieties lKi\'e long been known by different names in 

 popiihir [i;irlaiiee, ;iii(l are now recognised even in 

 scientific nomenclature, the first as the Trout (Sw. 

 Gralax, Stilmo tnitta), the second as the Salmon (Sw. 

 Blankhi.i-, SnJmn miUh). Tht; Sidmon is generally the 

 larger: it attains, according to l>i;cKi,Axn°, a length of 

 14 dm. and a weight of il^U kilo.'', and Fatid' men- 

 tions specimens as much as IB dm. long; but even the 

 Trout (if the determination be correct) sometimes mea- 

 sures nearly 1-1 dm.' 



The chief external distinction between these two 

 varieties consists in the more elongated form, the short- 

 er maxillaries, and the more scattered .spots of the 

 Salmon. In 1848 a fisherman from Elfl^arleby showed 

 LiLL.iEBoiiG a practical method of telling a Trout from 

 a Salmon merely by taking it in the hand. If you 

 grasp a Salmon round the tail, you have no difficulty 

 in holding it fast; but a Trout held in this manner 

 easily slips out of the hand. This is due to the greater 

 contraction of the peduncle of the tail in the Salmon, 

 a character \vhich also affords the safest expression of 

 the greater elongation of the body in this form. The 

 least depth of the tail in the Salmon is less than 28 % 

 (as a rule less than 25 %), in the Trout about 30 %, 

 of the preabdoininal length (the distance between the 

 foremost }iaints in the insertions of the pectoral and 

 ventral fins), fkit this character liolds good only in 

 adidt and typical specimens. The case is the same 

 with another character expressing the same difference 

 in the form of the body: the length of the dorsal 

 margin of the peduncle of tlie t;iil (behind the adipose 

 fin) is greater in the Salmon, less in the Trout, than

' According to information received by tbe Swedish Fisheries < 'nniinission of 1881 — 83, tlie Salmon in Sweden attains a length of 

 at least 1' 3 m. and a weight of at least 25' \ kilo.

 dm. and a weiglit of 7-'^ kilo.
