AMERICAN FISHES . 
“ Michigan Herring.” The Lake Herring is one of the most abundant 
fishes of the Great Lake region, probably second only to the White-fish 
in importance as a food-fish. It goes in large schools, and is taken in 
great numbers in .comparatively shallow waters. It ranges northeastward 
to Labrador, the eye becoming larger eastward. The sub-species sisco of 
Jordan is a form modified by residence in small deep lakes in Wisconsin 
and Indiana, and probably in Northern New England and New York. 
Its usual length is little more than a foot. Its mouth is much larger than 
that of the White-fish, and its range of food is doubtless greater. It 
usually remains in deep water until in November and December, when 
great numbers come near shore to spawn in the shallow waters. As a 
food-fish the Lake Herring ranks well, and although it is considerably 
inferior to Coregonus clupeiformis , it is sent to market in immense 
quantities. 
Coregonus Hoyi , occurs in Lakes Michigan and Ontario, in deep water ; 
in the lakes of Western New York (particularly Geneva Lake) where it 
sometimes dies in great numbers. It is known as “ Frost fish ” in some 
parts of New York. 
The Mongrel White-fish, Coregonus tullibee , is a species occasion¬ 
ally taken in the Upper Great Lakes, where it is generally considered a 
hybrid between a White-fish and a Lake Herring, hence the name of “Mon¬ 
grel White-fish.” It is a rare fish in collections, and nothing distinctive 
is known of its habits. Its range extends northward, to Alaska, where 
young have recently been taken in the Kowah River. 
The Menomonee White-fish, Coregonus quadrilateral!, inhabits the 
Lakes of New England, Upper Great Lakes, and is found northwestward 
to Alaska ; occurring at Kodiak Island in the Gulf of Alaska. It is re¬ 
placed in the Rocky Mountain, and Sierra Nevada regions by C. William- 
sonii. The name of “Round-fish” is given to it by Richardson, and 
that of “ Shad Waiter ” (Winnipiseogee Lake) by Prescott. In the Great 
Lakes it is much less abundant than the common White-fish, and its size 
is less than that of the White-fish. 
Rocky Mountain White-fish, Coregonus Williamsonii ’ occurs in the 
upper tributaries of the Missouri and streams flowing into the Columbia ; 
also in clear lakes from the Rocky Mountains to the Pacific ; it is abundant 
in the Sierra Nevada. This species is usually known as the White-fish ; 
in Utah as the “Mountain Herring.” It reaches a length of a little more
