ery of a New Hampshire charr characterized by such a 
synthesis of traits. 
Until the year 1885 but three species of trout, or, more 
properly, charr (a Gaelic word meaning red, or blood-col- 
ored), were recognized as native to New England, viz. : 
I. The Salvelinus fontinalis, or common brook trout. 
II. The Salvelinus namaycush, the longe, togue, lake, 
or Mackinaw trout. 
III. The Salvelonus stagnalis of Fabricius; oqguassa of 
Girard and Gunther, the diminutive blue-back of the 
Rangeley Lakes of western Maine—the last closely allied 
to species widely spread through Arctic America, as well 
as to the European saibling. 
From this classification is omitted Salmo agassizii, of 
Lake Monadnock, N. H., now recognized as a variety of 
brook trout ; and the Salmo hucho, or hunchen trout, men- 
tioned by Dr. Smith in his ‘‘ Natural History of the Fishes 
of Massachusetts,’’ 1833, and therein claimed to be related 
to the true hucho of the Danube. Its forked tail, dusky 
hue and reddish spots, coupled with the statement that it 
was brought to market in a frozen condition from lakes in 
New Hampshire and Maine, make it probable that the 
Massachusetts /wcho was merely a variety of namaycush. 
Even Prof. Jordan, in an article on the Salmon Family, 
published in ‘‘ Science Sketches” as late as 1888, is silent 
as regards a fourth New England species; although Prof. 
Garman, of the Museum of Comparative Zoology at Cam- 
bridge, in his paper on the American Salmon and Trout 
(1885), calls attention, under the head of Salmo fontinalis, 
to a form, Fig. 16, of which he says: ‘‘A knowledge of the 
younger stages of this fish from the same locality may lead 
to a separation of the form.’’ Subsequent research has 
led to such aseparation, and ichthyologists now admit the 
presence of a fourth variety of Salvelinus in New England 
—the alpinus aureolus, or golden-hued Alpine charr,
