prairies, where tbey feed on the small greeu lizards which aboimd there, 

 and which tliey canght with great dexterity. At Corpus Christi Han- 

 cock saw many of them "migrating northwards." Brown observed the 

 species but twice at Boerue. 



Genus ACCIPITER Brisson. 



99. Accipiter velox (WiLS.). Sharp-sliiuued Hawk. 



Brown notes the Sharp-shinned as a common winter visitant at 

 Boerne, and Dresser says that it is common at San Antonio, remaining 

 near there during the breeding season. Hancock saw several individ- 

 uals at different times near Corpus Christi. 



100. Accipiter cooperi (BoxAP.). Cooper's Hawk. 



Dresser states that this Hawk is not uncommon about San Antonio, 

 where he procured several specimens, and that it breeds on the Atas- 

 cosa and Medina Rivers, 



Genus PARABUTEO RiDGWAY. 



101. Paiabuteo unicinctus harrisi (Aud.). Harris's Hawk. 



Harris's Hawk was found by Dresser to be abundant " throughout 

 the whole country, as far east as the Colorado Kiver." He notes them 

 as breeding in the neighborhood of the San Antonio, Medina, and 

 Atascosa Elvers, laying their eggs in May. 



Genus BUTEO Cuvier. 



102. Buteo borealis (Gmel.). Red-tailed Hawk. 



This Hawk is " common throughout Texas at all seasons of the year," 

 according to Dresser, but neither Hancock nor Sennett appear to have 

 observed it at Corpus Christi. I saw a mounted specimen in a drug 

 store there, said to have been shot in the vicinity by Mr F. B. Arm- 

 strong. Brown found some half dozen pairs resident in the immediate 

 vicinity of Boerne. 



103. Buteo Iiarlani (Aui).). Harlan's Hawk. 



Dresser obtained one specimen of this Buteo, shot on the Medina Elver, 

 but he noticed the species on several other occasions. 



104. Buteo lineatus (Gmel.). Red-shouldered Hawk. 



" This bird I noticed all through the country from the Xueces Eiver 

 eastward. It breeds in the heavily-wooded river-bottoms of the Medina, 

 Guadalonpe, Atascosa, etc." (Dresser). 



105. Buteo lineatus elegans (Cass.). Red-breasted Hawk. 



Kot uncommon near San Antonio during winter, according to Dresser, 

 but he was doubtful as to whether it remained there to breed. 



106. Buteo abbreviatus Cab. Zone-tailed Hawk. 



In the Bulletin of the Xuttall Ornithological Club for 1879, page 76, 

 Mr. Brewster gives an account of the nesting of this hawk in Comal
