Dr. Shufeldt’s New Orleans specimen, an adult male, is in fine 
unworn plumage and has much less ochraceous beneath than is 
usual in eastern specimens ; it measures, wing, 56.5; tail, 55; cul- 
men, 13; tarsus, 23. Its wing formula is 4-3-5—2—6-1—7-8. 
Lloyd’s Texas specimen is the palest example I have seen; its 
bill, though long, is rather slender, and though in good plumage it 
has much less brownish and ochraceous than in eastern speci- 
mens. It measures, wing, 55; tail, 56; culmen, 11.5; tarsus, 22. 
Its tail is thus a trifle longer than the wing, the only instance in 
the species. The wing formula is 4—3—-2-5-1-6—7-8. 
An immature specimen from near Charleston, S. C., Nov. 1, 
1898, in unworn condition, measures, wing, 55.5 ; tail, 52; cul- 
men, 10.5; tarsus, 21. 5. 
The northern bird resembles ¢rchas in color, but comparable 
spring specimens are deeper and better colored, which is also the 
case with autumn specimens. Wearing produces similar effects 
as in the other form, so that summer specimens of both are quite 
similar except in size and wing outline. In drachidactyla we have 
a larger bird with a much stouter bill, longer wing and relatively 
shorter tail. The wing is less rounded, a greater interval separat- 
ing the 4th and sth primaries and a less interval the znd and 3rd, 
and the rst and 2nd. This results in a longer outer primary and 
in its being next to the sth in length, sometimes it follows the 4th. 
It is always longer than the 6th, not shorter as in the other forms. 
The formula is almost without exception 4—-3-2-5-1-6-7-8. A 
variation is 4-3-5-2-1-6—7-8, another 3—4-5—2-6-1—7-8, but 
these are rare and are evidently due to wearing, occurring on 
spring specimens. Specimens taken in Virginia near Washington 
in spring measure, males, wings, 52-55; tails, 48-51; culmens, 
II-12; tarsi, 20-21. Females, wings, 51-54; tails, 46—47.5 ; 
culmens, 11-11.5 ; tarsi, 17-18. In a series of Long Island May 
specimens the wings are 54-57; tails, 49.5-52.5. New England 
and Canada spring specimens are: wings, 55.5-57-5; tails, 49.5— 
53- Spring male specimens from the Bahamas: wings, 54-59 ; 
tails, 50-55.5. A series from the mountains of western Pennsyl- 
vania in summer: wings, 48-57.5; tails, 44-52. The largest 
trichas that I have seen from about Washington has a wing of 54, 
while the average is much less. A series of New York city autumnal
