HELMINTHOPHAGA. 117 
Colorado valley 1°, Texas 8 9.—Mexico °, Orizaba (Botteri 2, Swmichrast’), La Parada 
(Boucard**), Oaxaca and Cinco Sefiores (Boucard +); GuatemMaLa, Chimuy, Vera 
Paz (Sarg). 
This species has come under the notice of most of the collectors in Southern Mexico, 
where it appears to pass the winter months. It is found in the mountainous parts of 
the country, being apparently absent from the low-lying lands adjacent to the two 
oceans. In Guatemala it never came under our own notice; but a short time ago we 
obtained a skin from Herr Schneider, of Basle, to whom it had been sent by Mr. Sarg 
from Chimuy, a place in the vicinity of Coban, Vera Paz. This proves that the bird 
sometimes wanders thus far in its winter migration. 
Beyond our frontier it has been noticed during the colder months in Texas ®°%. 
Thence it spreads throughout the States and northwards to the Yukon river and the 
Great Slave Lake. In the eastern States it is rare and of uncertain occurrence, but 
yet has been met with in various places from Florida to Massachusetts 1°. 
H. celata breeds in the Arctic regions and in the higher mountains of Colorado, 
building on the ground a nest composed outwardly of fibrous bark and inwardly of 
grasses and moss and sometimes with a lining of some kind of fur 1°, 
The species seems subject to some variation in the colour of its plumage. This in 
the countries bordering the Pacific takes a more decided character ; hence these birds 
have been separated as a race and called H. celata, var. lutescens*.
