killed in May, on the return of the species to its breeding-quarters. These young hirds are decidedly'
more rufescent on the throat and flanks than older individuals; the spots heing slightly more distinct
on the sides of the hreast; under wing-coverts white, with ashy hases; axillaries ashy like the sides!
of the hreast; quills ashy helow, paler ashy along the edge of the inner web, and showing a pale
buff patch near the base of the quills.
Nestling. Much darker than the adults, and profusely spotted with large centres of orange-buff,
especially on the rump and upper tail-coverts; the sides of the face and throat bright orange-buff,
mottled with broad blackish edges to the feathers; the white hreast also profusely mottled with;
dusky crescentic bars at the end of the feathers, the sides heing washed with orange-huff.

In the British Museum are several specimens of T. salicicola from the Henshaw Collection, which
have been identified by Mr. Ridgway himself, and I have therefore been able to form a judgment on
the value of this race. As to the measurements of T. fuscesoens and T. salicicola, it will be seen
from the dimensions given by Mr. Eidgway that they overlap, although T. salicicola appears to be a
slightly larger bird, as a rule.
Taking the Henshaw specimens as typical, I can only say that, when they are compared with a
series of undoubted T. fuscesoens, the variation in tone between the more rufous T. fuscesoens and.
the more olive T. salicicola is so gradual that it seems impossible to draw any hard-and-fast line
between them.' The darker specimens likewise resemble T. ust-ulatus in winter plumage, i f it should
happen that a careless preparation of the skin has obliterated the distinctive orbital ring of the latter.
I may mention that intermediate specimens, which it has puzzled me to determine as to whether
they are T. fuscesoens or T. salicicola, come from Michigan, Corpus Christi, Texas, and Camacusa-
in British Guiana. The Texan bird I refer to T. salicicola, and the others to T. fuscesoenst
