NOTES ON LAND-LOCKED SALMON. 
BY CH ARTES Ge yAcukslNs. 
NOMENCLATURE AND RANGE. 
The term ‘“ land-locked salmon,” though it may be, and prob- 
ably is, a misnomer so far as it implies any forcible detention of 
sea-going salmon in fresh water, has come to be generally ac- 
cepted as applicable to all those salmon of Eastern North Amer- 
ica and of Europe that pass their entire lives in fresh water- 
They are all, according to the most recent conclusions of our 
American ichthyologists, members of the great species, Sa/mo 
salar, the common river salmon of the tributaries of the North 
Atlantic. In America they are found in a number of restricted 
localities, of which, besides several in the Canadian provinces, 
there are four in the State of Maine; namely: rst, the waters of 
the Saint Croix; znd, of one branch of Union river, Hancock 
County; 3rd, of Sebec River, a tributary of the Penobscot} and 
4th, of Lake Sebago and tributaries, in Cumberland County. 
The results of some inquiries that I have made relative to the 
salmon of Lakes Champlain and Ontario indicate that these, also, 
should be added to the list, though I believe that the salmon of 
Lake Champlain are now extinct. 
I have little knowledge of the salmon of any of these localities 
but those in the State of Maine, and their descendants in other 
States, and any general remarks I may have occasion to make, 
must be understood as applying especially to them. 
A COMPARISON WITH ANADROMOUS SALMON. 
To the anatomy of the land-locked salmon I have given none 
but the most superficial attention, and am not able to say wheth- 
er there exist any distinguishing marks by which they mav be 
unerringly separated from the normal Sa/mo salar, or from each 
other. The general impression made upon the fish-culturist 
who views them in their separate haunts is that the external dif- 
ference of form and color are sufficient to enable him easily to 
separate those of the several districts should they be presented 
in a promiscuous heap, but I confess that I should not dare to
