HORNED GREBE. 567 
inner quills white; lower parts pale silvery-ash, the sides watered or obscurely mottled, 
sometimes obviously speckled with dusky ; bill black, more or less yellow. at base. 
The young will be recognized by these last characters, joined with the peculiar dimen- 
sions and proportions. 
Habitat, the typical form, Europe. Var. holbdlli from Greenland and North America ; 
with this Asiatic and Japanese specimens are said. to agree. 
Rare spring and fall migrant, perhaps also winter resident. It has 
been taken several times on the lake, at the St. Mary’s and Licking 
Reservoirs and on the Scioto River, at Circleville, by Dr. Howard KE. 
Jones.

Tarsus about equal to the middie too without its claw; bill much shorter than the 
head, little more than haif the tarsus, compressed, higher than wide at the nostrils, 
rather obtuse; crests and ruffs highly developed. Small, length, about 14; extent, 24; 
wing, 6 or less; bill, about 2; tarsus, i+. Adult:—Above, dark-brown, the feathers 
paler edged; below, silvery-white, the sides mixed dusky and reddish; most of the 
secondaries white ; fore neck aud upper breast brownish-red ; head glossy black, includ- 
ing the ruff; a broad band over the eye, to and including the cceipital crests, brownish- 
ish-yellow ; bill black, yellow-iipped. The young differ as in other species, but always 
recognizabie by. the above measurements and proportions.

Rather common spring and fall migrant and summer resident, most 
frequently seen in the fall. Audubon states that it breeds in Northern 
Ohio, and Mr. Langdon gives the following regarding their supposed nest- 
ing in Ottawa county at the present time: 
“Two sets of eggs taken July 2d, I refer, with a query, to this species as the birds 
were not seen in either instance. They present such differences, however, in shape, 
coloration and complementary number, that they can hardly be credited to P. podiceps, 
and I therefore prefer to consider them under the head of P. cornutus, for the present at 
least. 
‘‘These eggs are chalky-white, with a faint, though definite, tinge of pale bluish- 
green, much like the tint of the Least Bittern’s eggs, and very unlike the pale 
whitey-brown of the eggs of P. podiceps observed by us; they are also more elongated 
in shape than the ordinary egg of P. podiceps, and taper nearly equally toward both 
ends,. which are decidedly pointed, rather more so than the eggs of P. podiceps; another 
important point of distinction is the number in a full set, whieh is apparently but two,
