of the lower parts, and the five to seven dark bars on the 
tail. The second year plumage by the transitional markings 
beneath, and of the four or five dark bars on the tail, the 
outer pair frequently as in the first year. In the adult there 
is considerable individual variation. In the United States 
the dark phase appears constant in the fall, and I have met 
with the gray-brown phase only in spring and early summer, 
and then considerably abraded as from: wear and weather. 
Of the series of skins in the Academy of Natural Sciences 
of Philadelphia, a single adult taken at Brownsville, Texas, 
is the only spring example of the dark type, and even in this 
the mantle is grey; an immature taken about the same time 
from that locality is very pale. “ In the adult the principal va- 
riation is in the continuity or distinctness of the anterior 
light band on the tail, and the extent and depth of the brown 
beneath. The first is characteristic of most specimens; it is 
broadest and most conspicuous, as well as less concealed by 
the coverts, in the females, and this appears to be the prin- 
cipal sexual difference.” Ridgway. Excepting Cuban and 
perhaps Porto Rican specimens, there appears to be no con- 
sistent geographical variation. Two Florida birds differ not 
at all from the northern examples. Riley states that he has 
found no individuals corresponding to the gray-brown phase 
in a series of Cuban skins, but that the dark phase is hardly 
or not at all different from the eastern United States exam- 
ples. The most constant differentiation between the Conti- 
nental and the Lesser Antillean forms, aside from the size, 
appears to be in the number and width of the barring of the 
thighs, the latter forms averaging narrower. 
An adult sexed as a female, taken at Baydte, Santiago de 
Cuba on Feb. 2, 1906, has the upper plumage seal brown 
narrowly edged with russet, fading into sepia on wings and 
mantle; upper tail coverts seal brown, barred with white 
and narrowly tipped with wood brown. Underparts pale 
buff to white, handed with mars brown, confluent on breast: 
thighs and tibe buff, banded with russet; under tail coverts
