This species is most closely related tu J), adihiidci', from Porto Rico ; but 

 in the latter the yellow beiieatli extends ))ack to the crissum, covering even 

 the sides ; tliere are also no streaks on the sides or back ; the ])roportions, 

 too, are quite different, the wings and tail lieiug scarcely three fourths as long, 

 while the IjiU and feet are much the same size, the tarsi even much shorter. 

 A specimen (No. 41,808 ^ ) from Belize, Honduras, differs so essentially from 

 the Fort Wliipple specimens, that it is, beyond doubt, entitled to a distinc- 

 tive name. The differences between these two very well marked races can 

 best be e.xpressed in a table, as follows : — 



(40,680, $, Fort Whipple, Arizona). Bill (from iio.stril), .30; tarsus, .60; wing-, 

 2.60 ; tail, 2.20. Superciliary stripe extending .20 behind the eye, that portion 

 behind the eye white ; yellow of juguhim not .spreading over breast (ending 

 1.3;j from tlie bill). Streaks of crown coalesced into a bi-oad stripe on each 

 sidi; ; those of back broad, and those on upper tail-coverts almost obsolete. 

 Wing-bands, .20 wide. Lore dusky-grayish. Hob. Fort Whipple, near Fres- 

 co tt, Arizona ; abundant, breeding (CoUEs) ..... var. t/raria'. 



(41,808, ^, Belize). Bill, .30; tarsus, .GO ; wing, 2.20 ; tail, 1.95. Superciliary 

 stripe scarcely passing the eye, wholly yellow ; yellow ofjugulum spreading 

 over breast (ending 1.60 from the bill). Streaks of the crown scarcely coalesced 

 along its sides; those on back not longer than those on crown, and those on 

 upper tail-coverts very conspicuous. Wing-band.s, .10 wide. Lore clcc]i black. 

 Hall. Belize, Honduras, resident ? ....... var. decora. 



Habits. We are indebted to Dr. KUiott Cones for all that we at present 

 know in reference to this recently discovered species. He first met with it 

 July 2, 1864, in the Territory of Arizona. Dr. Cones first noticed this 

 bird among the pine woods covering the summit of Whipple's Pass ol' the 

 Pocky ^Mountains. He saw no more in liis journey into ('entral Arizona 

 until lie was again among the ]iines at Fort Wliipple. There lie again 

 found it, and it proved to be a very common bird. Dr. Coues antieijiates 

 tliat this species will yet be found to occur in tiie forests of the San Fran- 

 cisco Jlduntaiiis, and tiiat its range will be ascertained to include all tlie 

 ])ine tracts of New Mexico and Arizona, from tlie valley of tlie Pdo Grande 

 to that of tlie (ireat Colorado liiver. He also has no doubt that it breeds 

 near and around Fort Wfiipple. 



Specimens found at Belize, first believed to be identical with those from 

 Arizona, are now referred to a race called decora. 



According to Dr. Coues's observations, the Warbler arrives at Fort ^^'hill- 

 ple about the 20th of April, and remains in that neighborhood until the third 

 week in September. It is found almost exclusively in ]iine woods, is active, 

 industrious, and noisy, and possesses very marked fiycatching habits, flying 

 out from its perch to catch passing insects. It has been, so far, found almost 

 e.xclusively among the tallest trees. 



In regard to the song of this species. Dr. Coues states that it appears to 

 have several different notes. One of these is tlie ordinary t»ip, given out at 

 ail times by both old and young of all kinds of small insectivorous birds.
