THE WHITE BASS AND THE YELLOW BASS. 33 
This is doubtless the Silver Bass of Canada (/e Silver Bass du Canade), 
the details of whose introduction into France, and successful propagation 
by M. Carbonnier, from 1877 to 1879, are recorded by that experimenter 
in the Bulletin of the Society of Acclimation for 1881.* 
The species at one time attained to commercial importance in the Lake 
Region, but has now greatly decreased in numbers. It is especially ad- 
mired by the anglers of Lake Pepin. 
Another species which closely resembles the Striped Bass is the Aorone 
interrupta, generally known as the Yellow Bass, but sometimes called 
THE YELLOW BASS. MORONE INTERRUPTA,. 
Bar-fish in the South. It is found throughout the lower course of the 
Mississippi, ascending the tributaries which are deep and sluggish, but 
not running past rapids or into the upper courses of the rivers. Jordan 
states that its range extends up the Ohio to the mouth of the Wabash or 
beyond, though it does not seem to be common anywhere except in the 
Lower Mississippi. It probably enters salt water, but of this we have no 
certain information. It is taken in considerable numbers in the regions 
where found, and is graded with the White Bass, which it much resembles 
in size and color. Little is known in regard to its habits. The criterion 
by which it may be distinguished from the White Bass is the low membrane 
connecting the two dorsal fins. Its color is yellow, not silvery, and the 
black stripes are very prominent.
