the line of division between the two colours ; hack of - neck
and upper surface of the body dark brown ; lower part of
the neck in front greyish-white ; under surface of body and
legs as in summer. _
The figure of the male in summer plumage in the illustration
at the head of this subject, was taken from the. specimen
given me by Mr. Morgan, and my note made on an examination
of the internal parts of this specimen, as mentioned
by the Rev. L. Jenyns, in his a Manual of the British Vertebrate
Animals,” page .253, was, stomach membrano-muscular,
csecal appendages each one inch:and a half in. length, w l
other figure, in the state, as to plumage, in which it i s called
the Dusky Grebe, was taken' from, a Specimen obtained, in
the London market, 'in March 18S£s and .row .also in my
own collection. My note of the internal appearance of this
bird Was, stomach muscular, a true gizzard, ^cpntained An-
sects,* two long1 csecal appendages from foÉï to five inches
each. From the difference in the substance of the parietes
of the stomach in these two specimens, and particularly in
the comparative length of the csecal appendages, I was at
first induced to suppose that Montagu and^Ahe Edit#?, of
the last edition of Pennant’s British Zoology were correct
in considering the Sclavonian-Grebe distinct from the-Dusky
Grebe, but I am now inclined to believe that, though the
specimen killed in summer plumage was adult, the other
was still an older bird. I find the csecal appendages in
Podiceps cristatus, killed in its first winter, when six months
old, only half an inch long; but in .an old bird these appendages
measure two inches in length.

Of the five species of Grebes fonnd in the British Islands,
the Eared Grebe appears tj^be; the most rare. Colonel Montagu
mentions that, during the many years he devoted attention
to ornithology he only obtained one specimen, and
