NATURAL SCIENCES OF PHILADELPHIA. 79 



black; hard parts of mouth livid blue, soft parts flesh colored. The color of 

 the under parts varies greatly from a very pale fulvous, almost white, to a de- 

 cided ferruginous, almost like canadensis. Sometimes the under parts are 

 smoky brown, as in Picus Harrisii from California and Oregon. 



(129.) Sitta canadensis Linnaeus. 



Rare; perhaps only accidental. (Fort Yuma, Ives.) Not met with by me. 

 Dr. Cooper never saw it at Fort Mojave. 



128. Certhia Americana Bonap. 



It is a little singular that I never saw a specimen of this species in Arizona, 

 though it is generally distributed over the Territory. Dr. Kennerly procured 

 it very near the present site of Fort Whipple. 



PARI DM. 



129. Lophophanes inornatus (Gamb.) Cass. 



Winter resident chiefly; but some doubtless remain through the year, 

 breeding in the neighboring mountains. Not very abundant Emphatically 

 an evergreen oak species, eschewing the pines, and frequenting open hill- 

 sides. 



Iris black. Bill black ; horn blue along its commissural edges and at base. 

 Feet deep leaden blue. 



130. Lophophanes Wollwebkri Bonap. 



Permanent resident; common, more so at least than the preceding. Usually 

 semi-gregarious except when breeding. Found in all situations; but 

 chiefly affect the oak thickets, and the chaparral of open hillsides. Generally 

 distributed through the Territory, and extending southward into Sonora. 



131. Pcscile montands (Gamb.) 



Resident throughout the Territory, more particularly its pine tracts. No- 

 where very numerous. The only species of black capped and throated Tit- 

 mouse ascertained by me to inhabit the Territory. 



The American black-capped Titmice seem to me generically distinct from 

 Linnseus' type of Parus ; while they are entirely congeneric with /'. palustri* 

 of Eutope, Kaup's type of facile. 



P. seplentrionalis is recorded from the Southern Rocky Mountains, and may 

 hereafter be added to the Whipple list. (Fort Massachusetts, Dr. Peters, 

 U. S. A.) 

 (132 ) Auriparus flaviceps (Sund ) Baird. 



" Abundant in the Colorado Valley, where it is a permanent resident," 

 'Cooper.) I do not think it leaves the valley for the mountainous portions of 

 the Territory. 



133. Psaltriparus pi.umbf.us Baird. 



Resident and very abundant at all seasons. Decidedly gregarious, and, ex- 

 cept when mated, always found in '-flocks" of from five or six to as many 

 as fifty or more; active, restless and noisy, familiar and unsuspicious. Es- 

 chews pines, and keeps entirely in the thick shrubbery of the hillsides, or the 

 denser brush of creek bottoms and ravines. 



No. 752 and others; iris bright yellow. No. 753 and others; iris dark 

 brown This difference seems entirely accidental, and not dependent upon 

 age, sex or season. 



The original types of the species described as Psaltria plumMa, by Prof. 

 Baird, are trom the Colorado Chiquito River. 



ALA UDIDJE. 



134. Eremophila cornuta (Wils.) Boie. 



Common ; permanent resident in all situations adapted to its wants.
