SILVER TROUT. 
65 
of the eye equals the length of the snout, and the length of the head is one-fourth of the total, 
without caudal; the length of the head of a twelve and a half inch specimen (fig. 18) equals 
the depth of the body, and is contained four and three-fourths times in the length of the body 
and head.” 
This is the original description but conveys practically nothing distinctive. The princi- 
pal characteristic differences noted by Garman have already been quoted. 
1889. — Bean ( 1 . c.): “This handsome little trout is found in some small lakes of New 
Hampshire. Garman, who was the first to describe it, considers it a variety of the brook trout. 
In coloration it has considerable resemblance to this species in its banded back fin and tail fin, 
but it never has vermiculations, or mottlings, on the back. The tail is forked and there are 
teeth on the root of the tongue. The stomach is stout and the number of appendages at its 
pyloric end in some examples is forty-nine. The scales are about as large as in the brook trout 
and the shape is similar in specimens of equal size of the two kinds. Garman observed that 
the young are more slender, with deeper fork of the tail and the sides more silvery than in the 
brook trout, and ornamented with clouded parr marks. Fresh specimens seen in the national 
collection in 1884 were silvery gray on the upper parts, whitish below. The fins on the breast, 
belly and beliind the vent were chiefly vermilion. A few vermilion spots on the sides. 
“The Dublin pond trout is generally designated as a light-colored, slim, and silvery fish. 
It is said to spawn on the same bed but about two w’ceks earlier than the brook trout, the latter 
not making its appearance until the smaller and more graceful relative has disappeared to its 
reputed abode in deep water. Garman’s largest individuals were about a foot long.” 
In this general, rather than in his technical discus.sion. Bean gives some of the essential 
diagnostic characteristics. Here the former assertion that it is a Salvelinus “without hyoid 
teeth” is modified by the statement that there are “teeth on the root of the tongue.” He refers 
also to the distinctive coloration, which is one of the marked peculiarities of the species. 
In Forest and Stream, March 10, 1900, p. 191, A. N. Cheney referred to the Dublin Pond 
Trout as observed by him at the Sportsman’s Show. Contrasting it with the Brook Trout, he 
described it as follows: “There are no vermiculations on the back, which is a solid greenish 
color, with silvery glints in certain lights; caudal fins more forward; fins paler, general pinkish 
hue; the black stripes in fins fainter, and the white border ^ dirty white; spots lemon color, 
no halo. Fish generally more slender than the brook trout. 
“While looking at the Dublin Pond trout I was fortunate enough to meet Mrs. Dwight and 
her daughter, of Boston, who reside in summer at Dublin Pond, and they very graciously went 
back to the tanks to give me such information as they could. When the fish were netted from 
the water. Miss Dwight w'as very enthusiastic about the fish, and said they were very fair 
types of the trout as she knew them at the pond, but there she had observed that the spots 
were orange rather than lemon, but the colors fade quickly.”
