The specimen referred to above is the first record of the occurrence

in America of a genus heretofore considered as belonging exclusively

to the Old World.

This bird was described in 1869 as a possible variety of _P. coccinea_

of Europe. On submitting the typical specimens to Mr. H. B. Tristram

of England, it was decided to be a well-marked and distinct species,

as explained in the following extract from a letter received from him.

“The coloration of the back is the same as in males of _P.

coccinea_ and _P. rubicilla_, and differs from the coloration of

the ♀ in all three species. In all the ♀ has the back brown

instead of slate-colored. Your bird, however, differs from _P.

coccinea_ in having the under parts of the same color as the ♂ of

_P. griseiventris_ with a slightly redder hue on the flanks,

while _P. coccinea_ is a brilliant blazing red. In this your bird

is like _P. murina_ of the Azores, but that has no white on the

rump.

“Nor can it be ♂ juv. of _P. coccinea_, because it has the

_black_ head, and the young assumes the black head and red breast

simultaneously, or rather the red begins first. It differs from

_P. nipalensis_ in having a black head and broad white rump, as

well as in size.”

Dr. O. Finsch, of Bremen, agrees with Mr. Tristram in considering it

as specifically distinct, and says that the long white shaft-streak on

the outermost tail-feather is to be considered as one of the peculiar

characters, and that in general it resembles the female of _P.

griseiventris_, LAFR., but differs in having the back beautiful

ash-gray.

HABITS. This new species of Bullfinch, having a close resemblance to

the _P. coccinea_ of Europe, was obtained by Mr. Dall, near Nulato,

Alaska, January 10, 1867. An Indian brought it in alive, but badly

wounded, having shot it from a small tree near the fort. He had never

seen anything like it before, nor had any of the Russians. Captain

Everett Smith had, however, met with several flocks of the same

species near Ulukuk. This specimen was a male, with black eyes, feet,

and bill, and was the only bird of the kind met with by Mr. Dall.

In size it is about equal to _P. coccinea_, which is now quite

generally considered to be simply a large race of the common Bullfinch

(_P. vulgaris_), and the habits of the American bird are doubtless

similar to those of its congeners. The European races inhabit the

mountainous regions of Northern and Central Europe, appearing in large

flocks in December and January in the more southern regions. In their

return in spring to their summer quarters, they move in smaller

numbers. They nest in the mountain forests, on trees or bushes. Their

nest is usually but a few feet from the ground, is beautifully wrought

in a cup shape, made externally of small twigs, blades of grass, and

rootlets, lined with coarse hair. They lay five eggs, the ground-color

of which shades from a light blue to a bluish or a greenish white,

with brown and violet-colored spots, that usually form a ring around

the larger end. Their food is grain and small seeds, and, in spring,

the buds of certain trees.

The Bullfinch is a favorite cage-bird, soon reconciled to confinement,

and capable of being taught to whistle whole airs of opera music with

wonderful exactness and beauty.
