dited to the Territory. Although by no means a complete exponent of the 

 birds of Soiithern Arizona, the list is valuable in clearly indicating some difl'er- 

 ences between the avifaunas of the southern desert and northern mountainous 

 portions of the Territory. Compare the species mentioned below with those 

 characterizing the Fort Whipple fauna, as elucidated in my " Prodrome," 

 Pr. A. N. S. Phila. Jan. 18ti(j. 



In my "Prodrome," 245 species are enumerated ; one of which (Orthiola 

 flaveola) was inserted by mistake. The present collection raises the number 

 to 248. The various species mentioned passim in my paper as of probable 

 occurrence, will, when substantiated as inhabitants of the Territory, further 

 increase the number to about 2(J0. 



iSome manuscript notes with which Dr. Palmer has favored me are placed 

 in quotation marks. Species known to occur throughout the Territory are in 

 small capitals ; others iu italics. 



Cathartes ADRA,*Linn. 

 Falco sparverius, Linn. 

 AocipiTER CooPEKi, Bouap. 



"Nesting, June 1st, iu crotches of cottonwood trees along river bottoms." 



Aquila canadensis, Linn. 



One of the southermost localities on record for this species. 



Geococcyx californianus, Less. 



Chiefly southern and western Arizona. Rare or casual at Fort Whipple. 

 " Very destructive to small animals, snakes, and hard-shelled insects." 



Cliordeilcs texensis, Lawr. 



Chiefly southern and western Arizona. Not observed at Fort Whipple, 

 where C. Uenryi is abundant. 



Centurus ui-opygialis, Baird. 

 Chiefly southern and western Arizona. Rare or accidental at Fort Whipple. 



Myiarchus mexicanus, Kaup. 



" Is very fond of hovering around the giant cactus, Cereus giganteua, when 

 in bloom, to catch the wasps and bees. Builds a loosely constructed, flat nest, 

 often in dwelling-houses." 



Sayornis sayvs, Bon. 



The egg of this species. Prof. Baird writes me, is much like that of Empido- 

 nax TraiUii. Dr. Palmer's specimens are the first ones ever obtained. "The 

 nest was procured May 3d, from the eaves of a house. The parent birds, when 

 alarmed. Hovered about uttering plaintive cries, and returned to renew their 

 mournful notes for several days after the invasion of their home." 



Pyrocophahis mexicanuf:, Sclater, P. Z. S. 1859, p. 45. 



Southern and western Arizona. Has not been found as high as Fort 

 W^hipple. 



Aftliis Costa; Bourc. 



Chiefly southern and western ; perhaps to Fort Whipple. 



Trochilus Alexandrl, Bourc. 



I included this species in my " Prodrome " (p. 20), mainly on the strength 

 of its occurrence in the Colorado Valley, very near the river (Mojave River, 

 Dr. J. G. Cooper). Dr. Palmer is, I believe, the first to detect it actually 

 within the Territorial limits. Possibly it should be in small capitals. "Nest 

 six feet high, in a bush, in a deep ravine." 



TuRDUs MiGEATORius, Linn. 



SlALIA MEXICANA, SwaiuS. 



Antuus ludovicianus, Licht.
