Feb 6] | BREWSTER—A RACE OF HENSLOW’S SPARROW. 79 
others, however, and perhaps should be referred to susurrans. 
As both were taken early in the season, — on April 24, — they 
may have been migrants bound elsewhere to pass the summer. 
Twenty-six Henslow’s sparrows taken at various dates from 
October to April in our South Atlantic States, a favorite winter- 
ing ground for the species, are included in my collection. Al- 
though mostly immature, they may be identified subspecifically, 
without much difficulty, by keeping in mind the characters 
which serve to distinguish adult breeding birds. Thus deter- 
mined, fourteen of these Southern specimens seem to represent 
the Ohio Valley form, and twelve its subspecies susurrans. 
My former mistaken impression that the Henslow’s sparrow 
of Virginia might be considered typical of the species, was largely 
responsible for the separation of a South Dakota form, occidenta- 
lis, described in 1891 and since included in the A.O.U. Check- 
List. Although differing very satisfactorily from Eastern birds, 
it is perhaps not sufficiently unlike those of the Ohio Valley to 
merit continued recognition as a subspecies. That question may 
as well rest, however, until more material has accumulated to 
throw further needed light on it. 
While in pursuit of quail near Osterville, Massachusetts, on 
November 6, 1874, I shot a Henslow’s sparrow, flushing it among 
scrubby pitch pines scattered over a wind-swept hilltop remote 
from any marshy ground. This specimen has since been valued 
because taken at a seasonal date so late and in a locality where 
no such bird was looked for or seemed likely to occur. It now 
derives additional interest by reason of the fact that in every 
respect, apparently, it is an ultra-typical example of the Ohio 
Valley form and hence true henslowi. No other specimen thus 
characterized has ever, to my knowledge, been secured any- 
where in New England.
