86 FISH GALLERY. 



migratory, others not ; they are spread over the whole of Europe 

 and North America. 



Of the species exhibited attention is directed especially to the 

 following : — the Lake-Wenern Trout (Salmo venernensis), a non- 

 migratory species ; a large Sea-Trout from the River Narenta, 

 Dalmatia (S. dentex) ; two male British Sea-Trout (S. trutta) with 

 extraordinary development of the jaws; a large specimen of the 

 Alpine Char (S. alpinus) from Nova Zembla ; the Brook-Trout of 

 North America (S. fontinalis and S. hoodii). The Common Trout 

 (S. fario) has been successfully introduced in rivers and lakes of 

 Tasmania and New Zealand, where it grows to a size rivalling that 

 of the Sea-Trout and Salmon, finding at present an abundance of 

 nourishing food in the small native fish (especially Galaxias), which 

 in the course of time will be brought to the verge of extinction. 

 In a tank on a table-case between wall-cases 17 and 18 a beautiful 

 large specimen of a Trout (S. fario) is exhibited, which has been 

 reared in New Zealand, and was captured in the estuary of the 

 River Waimakariri ; in its size it is quite equal to the large Trout 

 sometimes found in the River Thames, which it also resembles in 

 general appearance. The Smelt (Osmerus eperlanus) ; the Vendace, 

 called White-fish in North America (Coregonus,fi.g. 73), numerous in 



Fig. 73. 



Yendace (Corec/onus vandesius). (From Loch Maben.) 



speciesin Europe and North America, and the Graylings (Thymallus) 



are other well-known and highly esteemed members of this family. 



The Galaxiidm resemble the Pike in the disposition of their fins 



but are confined to freshwaters of Temperate Australia, Tasmania,
