SYNOPSIS OF CLASSIFICATION OF LAKE SALMON. 117 



from the sea salmon or from the trout, Salmo salar lacustris of Hardin or S. lacustris of 

 Nilsson. With Widegren's conclusion Malmgren did not fully agree, saying in effect 

 that the Ladoga salmon distinguished itself by a number of characters and biological 

 traits, acquired by thousands of years residence in the lake. He therefore regarded it as 

 a 'variety' of 'Trutta Salar,' as he designated the sea salmon {Salmo salar) and gave to 

 the Ladoga form the name of 'Trutta relida.' 



He stated that this fish could be recognized at sight, by its smaller size and different 

 distribution of the black spots on the body; those of salar being few and usually situated 

 above the lateral line, while those of relicta were rather numerous below the lateral line 

 anteriorly above the pectoral fin, directly behind the gill cover. 



In 1866, GUnther (1866, p. 107-110) described a salmonid from Lake Wenern, which 

 he supposed was the 'silfverlax,' as a trout and stoutly maintained that it was quite 

 distinct from Salmo salar. But it appears, according to some authors, that his trout, 

 which he names Salmo hardinii was not the Silfverlax form of the salmon but was really 

 a trout. 



Regan (1920, p. 27) refers to two 'fine specimens' of male and female 'Venern Salmon' 

 in the British Museum, under the name of Salmo salar hardinii. Thej' were said to be 

 24 inches long and together weighing 17 pounds; also a female 21 inches long. The 

 fish are said to be deep and profusely spotted and to have 12 or 13 scales between the 

 adipose fin and the lateral Une but in other respects typical salmon. The number of 

 scales between the adipose fin and the lateral Une is that given by Gunther for Salmo 

 hardinii and the usual number for Salmo trutta or 'Sea trout,' and the species is quite 

 Ukely correctly identified but probably it is not the 'silfverlax' form of the salmon. 



Berg (1916) gives to the salmon of lakes Ladoga and Onega the name 'Salmo salar 

 L. morpha relictus (Malmgren),' and his synonomy of this form comprises: 



'Trutta salar var. relicta Malmgren. Finlands Fisk Fauna, 1863, p. 59 (Ladoga lake, 

 at Kekshalm). 



'Salmo relictus Kessler [Fishes of St. Petersburg Province], 1864, p. 173 (Ladoga lake, 

 Volkhov, Sias, Svir). 



'Salmo hardinii GUnther. Cat. Fish, vi, p. 107 (Venern L.). 



'Salmo salar Kessler [Material towards a study of Onega L.] 1868, p. 65, (Onega lake 

 and its tributaries). — Pirshkarev [Fisheries of Onega Lake] 1900, p. 36.' 



He says that from Ladoga Lake it enters the rivers Volkhov, Sias, Svir (Paska, Ojat) 

 and from Onega Lake it enters the Shua, Suna, Vodla, Povenchanka, and others. 



Berg regards the salmon of Lake Venern and the lakes of Maine, New Brunswick, and 

 Lake St. John of Quebec {i.e., the ouananiche) as entirely analagous to this form. 



The Maine fish wliich appears to have been earUest known to anglers, first to be de- 

 scribed, and first to receive a technical name was the Sebago Lake form, to which 

 Girard in 1853 (1854, p. 38) gave the name Salmo sebago. 



However, the first use of the name Salmo sebago was by Henry WiUiams Herbert 

 (Herbert 1849, p. ix, 18, 21, 22, 23 and 168) who gave it to a 'Sebago Trout' of which 

 he had heard but never seen. Li the Ught of present knowledge and that he was told
