Dublin Pond Trout 



Dublin Pond Trout 



Salvelinns agassizii (Garman) 



in certain ponds or lakes in New Hampshire, notably Dublin 

 Pond, Lake Monadnock, Centre Pond, etc., is found a trout 

 whose colouration is pale grayish, and with fewer red spots, 

 thus resembling the lake trout. Otherwise it does not appear to 

 differ from the brook trout, except that the young are said to 

 be rather more slender, the caudal notch slightly deeper, and 

 the sides more silvery. The young are much darker than the 

 adults. This trout reaches a length of 7 or 8 inches. 



Dolly Varden Trout 



Salvclimis parkci (Suckley) 



This interesting charr is found in the streams and lakes of 

 Montana, Idaho, Washington, Oregon and California, south to the 

 Sacramento basin, and northward in coastal streams to the Aleu- 

 tian Islands. It is found only in Pacific drainage. Though res- 

 ident in fresh water, and scarcely at all migratory, it often 

 descends to the sea, and is frequently taken in salt and brackish waters. 

 In small mountain brooks at Unalaska and elsewhere dwarfed forms 

 occur. 



This is the charr which has been known in the books until 

 recently as Salvelmus malma, under the belief that it was identi- 

 cal with the malma of Wnlbaum from Kamchatka; but recent 

 investigations have shown the American fish to be distinct from 

 the Kamchatkan species.
