354 EEPORT OF COMMISSIONER OF FISH AND FISHERIES. 



Mi^i^ratory salmon of large size were at that time speared on the same 

 grounds where the small salmon are now taken in great numbers, and 

 which are never over five pounds in weight. 



I have published but one other paper on the Salmonidw, that on the 

 togue, which is printed in the Maine Geological Eeports of Hitchcock's 

 Survey, and I have no doubt but that the description is correct, and 

 the fish new to the scientific world. 



The Sahno Gloveri is nothing but a parr. I examined the fish several 

 years before Girard saw his specimen, and recognized it as the young of 

 the migratory salmon. 



They have disappeared from Union Eiver since the extinction of the 

 salmon. 



Yours, truly,

2. — *THE TOGUE. 



Sahno toma, Hamlin. 



This trout, known among the aborigines as the togue, tuladi, &c., has 

 been classed by some observers as identical with the Salmo hucho of 

 the Danube and of the lakes of Northern Europe ; but in these classifi- 

 cations peculiarities of anatomical structure have been overlooked, and 

 the habits of the two fishes have also been noted as similar, whereas in 

 reality they present great contrasts ; for the one, agile and alert, seeks 

 the swift and foamiug currents of the clearest streams ; and the other, 

 sly and sluggish, haunts always the quiet waters of the deepest lakes. 

 It is mentioned by Mr. Gesuer in his report upon Kew Brunswick, and 

 identified with the Sahno lacustris of Lake Geneva ; a ])roper exami- 

 nation of the two fishes, however, will satisfy the naturalists that few 

 positive analogies can be drawn ; and, again, it is identified with the 

 Sahno ferooc of Loch Awe, in Scotland, in the descriptive catalogue of 

 fishes of New Brunswick, by Mr. Perley, who identifies from the charac- 

 ters drawn by Sir W. Jardine and Mr. Yarrell, some of which would cer- 

 tainly lead the observer, unless minute, into the same error ; for it can- 

 not be denied that g'reat similarities are to be observed, but there are 

 also as many with the S. erytJirimis of Siberia. 



In shape it is not so elegant as that of some other species of the ♦ 

 Sahnonidw, but its whole form indicates great strength and swiftness, 

 although it has the reputation of beiug slow and sluggish. The female is 

 more perfect in its proportions than the male, not having that gibbous 

 appearance at the nape, where the outlines of the head pass into those 

 of the back, and, besides, its general contour is more delicate. 



A rich, -pearly luster covers the ventral regions, deepening into russet
