which were three and three quarters inches from 
the end of the middle toe to the hip-joint; and the 
deep uniform olive-brown of the upper parts, and 
the gray of the lower. It proved to be the gray- 
cheeked thrush, named and first described by Pro- 
fessor Baird. But little seems to be known con- 
cerning it, except that it breeds in the far north, 
even on the shores of the Arctic Ocean. I would 
go a good way to hear its song. 
The present season I met with a pair of them 
near Washington, as mentioned above. In size 
this bird approaches the wood thrush, being larger 
than either the hermit or the veery; unlike all 
other species, no part of its plumage has a tawny 
or yellowish tinge. The other specimen was the 
northern or small water-thrush, cousin-german to 
the oven- bird and half brother to the Louisiana 
water-thrush or wagtail. J found it at the head of 
a remote mountain lake among the sources of the 
Delaware, where it evidently had a nest. It usually 
breeds much farther north. It has a strong, clear 
warble, which at once suggests the song of its con- 
gener. JI have not been able to find any account of 
this particular species in the books, though it seems 
to be well known. 
More recent writers and explorers have added to 
Audubon’s list over three hundred new species, the 
greater number of which belong to the northern 
and western parts of the continent. Audubon’s 
observations were confined mainly to the Atlantic 
and Gulf States and the adjacent islands; hence the
