SILVER TROUT.

ruary and IVIarch. Othors say they are brook trout, and cannot be taken in the closed season, 
from the 30th of September to the 30th of April next following. 
“So anxious are parties to take the fish that in the months of January, Febiaiaiy, March 
and April they are, in their opinion, ‘lake trout.’ As the close season begins then on lake trout, 
the same parties call them brook trout after April 30 to Sept. 30 (open season for brook trout). 
This is quite an ingenious contrivance for the fishermen, but destructive to the fish. The com- 
missioners, finding such a diversity of local opinion, caused several of this species of trout to be 
taken and sent to the Agassiz Museum at Cambridge, Mass., for investigation, and they were 
reported ‘as a w’ell-marked variety of brook trout.’ Several were also sent to Prof. Baird, U. S. 
Fish Commissioner, Washington, D. C., and were pronounced by him to be a variety of brook 
trout.’ Hereafter there will be no mistake in regard to the variety, as that question has been 
settled, and they will not be taken as lake trout without encountering trouble with the local 
fish wardens and commissioners.’’ 
Although at a' late date, it remained for Mr. Samuel Carman, of the Museum of Compara- 
tive Zoology, in 1885, to concur with Agassiz regarding the fish and he accordingly described 
it as new to science, under the name of Salmo agassizii (see synonymy). After giving it this 
specific name and describing it technically. Carman adds: “A variety of the brook trout; 
apparently restricted to the small lakes in the neighborhood of Dublin, Jvew Hamp.shire. Com- 
pared with those of S. foniinalis, the young are rather more slender, the caudal notch slightly 
deeper, and the sides more silvery. The young are much darker colored than the adults; on 
both the red spots of the flanks are large and numerous. On the adult figured, fig. 18, the brown 
color has become so much bleached that the specimen is nearly uniform silvery , \ery faint 
indications of the red spots remain. The differences between the young of S. foniinalis and 
those of this variety are even more marked than those between adults; side by side, the clouded 
parr-marks or bands at once distinguish the young of S. agassizii. Apparently it is later in 
attaining sexual development, and has the appearance of a deep water species Dublin 
Pond; Lake Monadnock, Keene, N. H.; Center Pond.’’ 
The localities mentioned by Carman indicate three separate places, one of which, at least, 
is supposed to be in Keene. As a matter of fact, the three names are synonymous and the 
lake is in Dublin, somewhat remote from Keene. Carman apparently hastily inferred from 
Baird’s mention of the locality that Center Pond was different from Dublin Pond and for some 
other reason that the latter was different from Monadnock Lake. 
Carman’s description of the fish appears later in the present paper, together with other 
descriptive matter. 
The next published reference to the fish appears to be that by David S. Jordan as “Note 
on Mr. Carman’s Paper on ‘The American Salmon and Trout”’ in the Proceedings of the 
United States National Museum for 1885 (see synonymy).
