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 venerner t sis\ a non- 

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

 Dalmatia (S. dentex] ; two male British Sea-Trout (S. truttd) 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 

 B/iver Waimakariri ; in its size it is quite equal to the large Trout 

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

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

 called White-fish in North America ( Coregon us, fig. 73), numerous in
