THIRTEENTH ANNUAL MEETING. 35 
This is the common white-fish, and is the object of the most 
important of the fisheries of the great lake region. We have the 
typical form of this species from Lake Champlain to the east- 
ward, and from Manitoba to the westward. The range of this 
species has also been greatly extended by artificial introduction. 
The maximum weight of the species is said to be twenty-two 
pounds, but the average weight will perhaps. scarcely reach ten 
pounds. The reported occurrence of this species in the Yukon 
river, Alaska, is apparently unwarranted, a re-examination of 
our Alaskan material showing that the supposed C. clupezformzs 
of the Yukon is really C. kendcotti?, a species which grows to even 
a larger size than C. clupeiformis, but which is really not very 
closely related to that species. 
It is worthy of mention that the young of C. clupetformis have 
a much greater number of scales in the lateral line than the adult, 
some examples of which are here exhibited showing as many as 
ninety scales while the average number in the adult is but sev- 
enty-five. 
The following additional information about the white-fish has 
been extracted from the published writings of Mr. J. W. Milner: 
The fishes are not evenly distributed throughout the lake, but 
range in large colonies and run near the shore at different 
points, while the majority of localities may be destitute of fish. 
The statistics of nine principal fish-markets on the lakes show 
the proportion of lake-herring handled to be one-sixth, while 
the low rates herring command in the markets would pro- 
duce only about one-thirtieth of the amount realized from 
the whole quantity of fish handled. This shows the small 
value of the herring to the fishermen, in the herring localities. 
In the whole product of the lakes it would be of much less con- 
sequence. 
The white-fish is found in all depths in more or less abun 
dance, not only in the spawning season, but at all times. Young 
white-fish seek the surface, and they are strong and vigorous 
from the time they leave the egg. In their early life, therefore, 
they are not much preyed upon by voracious fishes, and the 
swarms of cyprinoids and Chirostoma (?) which are abundant at
