tion may be sought in the habits of the Sunapee saibling, 
as already described, or in the ignorance of the few who 
in old times may ever have seen it, and who cared for noth- 
ing beyond the fact that it was good to eat. 
Ford’s Pond in Warren, and Silver Lake in Madison, are 
associated with traditions of the fall spearing on their 
spawning beds of large, high-colored trout, which are be- 
lieved, from reports as to their habits and appearance, to 
have belonged to this same species. These two ponds, 
then, may represent a traditional habitat. The waters of 
Silver Lake find their way into the Saco; I was unable to 
learn whether Ford’s Pond discharges into the Connecti- 
cut, or through Baker’s River into the Merrimac. 
In April, 1893, a four-pound specimen of a square-tailed 
trout was sent to me from Swan Lake, near Belfast, Maine. 
It was remarkably like the aureolus of Sunapee, from 
which fish it differed in having a large mouth, well-armed 
with teeth, and a mottled dorsal fin. The pectoral, ven- 
tral and anal fins were orange in hue, but smaller than in 
the case of the Sunapee species. Prof. Garman inclined 
to the opinion that the Swan Lake fish (judging from this 
one specimen) is a form of Salvelinus fontinalis. Were 
hybridism possible, I should suspect a cross between the 
brook trout and the American saibling. At first sight 
one would certainly pronounce the Swan Lake fish an 
aureolus. 
Swan Lake is but a short distance from Flood’s Pond, 
the valley of the Penobscot lying between the two. 
Iam under obligations to Dr. Bashford Dean, of the 
Department of Biology, Columbia College, for material as- 
sistance in determining the following anatomical descrip- 
tion of the Sunapee saibling: 
Two specimens of one pound and three pounds respec- 
tively were carefully examined.
