doubtless be cleared up in the ensuing volumes of the Histuire 

 lies Polssons. The identity of the salmo salar itself on both 

 sides of the Atlantic has not been satisfactorily settled, and some 

 interesting facts in the history of the fish as an inhabitant of Lake 

 Ontario require to be ascertained ; for instance, whether it de- 

 scends to the sea after spawning, or whether, like the salmon 

 of Lakes Wenern and Wettern, in Sweden, it passes its whole 

 life in fresh water f, recruiting in the depths of the lake, and 

 spawning in the feeding streams. The truth of the report, that 

 none of the salmon which ascend the Columbia, or the rivers of 

 New Caledonia, return again to the sea, deserves to be inquired 

 into : — the same thing has been asserted of the salmon of North- 

 ern Asia. 



ClupeoidecB. — This family is also more numerous in North 

 America than in Europe, the latter country yielding only nine 

 or ten species belonging to the genera clupea, alosa, and en- 

 graulis. Hiodon, a genus peculiar to America, has much affinity 

 to the salnionoidece . 



Sauroide(E. — This family contains only two existing genera, 

 lepisosteus, peculiar to America, and jjoli/pterus to Africa J.
