BIRDS. 177 



HYPOTEIOECHIS FEMORALIS, (Temm.) 



Falco femoralis, Temm. PI. col. I, livraison 58. 



Harpagus hidentatus, (G-ray,) Gay, Fauna Chilena, Aves, 230. 



VuLG. Alcon or Halcoii. 



Figures. — Temm. PI. col. I, PL cxxi, cccxliii. 



A very handsome South American Hawk, recently added to the fauna of the United States by 

 Dr. Hermann, who observed and obtained fine sjiecimens in New Mexico. 



This species is trained for the pursuit of the smaller gallinaceous birds, and is highly esteemed 

 by the Chilean falconers. It is stated by Mr. Bridges (Proc. Zool. Soc, London, 1843, p. 109) 

 to become docile and to follow its master in so short a period as fifteen days after its capture. 



STEIX PEELATA, Licht. 



Strix perlata, Licht. Verz. 1823, 59. 



GrAY, Fauna Chilena, Aves, 257. 

 VuLG. South American Barn Owl. Lechuza. 



A species peculiar to South America, and much resembling Strix pratincola of North America 

 and the European Strix flanimea. The most readily observed distinctive character is the longer 

 legs, and especially the tarsi of the present bird, (as indicated in the description of Prof. Licht- 

 enstein,) in addition to which, it is much smaller than the North American species, and smaller 

 also than Strix flammea. 



This Owl is represented as of rather unusual occurrence in Chile, but inhabits sparingly 

 decayed buildings in all parts of the country. It appears to be very similar in its habits to the 

 common species of this genus. 



BUBO CEASSIEOSTEIS, (VieUl.) 



Strix crassirostris, Vieill. Nouv. Diet. VII, 1817, 44. 

 Ulula crassirostris,, (Vieill.) Gay, Fauna Chilena, Aves, 254. 

 Strix macrorhyncha, Temm. PI. Col. II, about 1823. 

 VuLG. South American Horned Oivl. Tucuquer. 

 Figure.— Temm. PI. Col. II, PI. Ixii. 



Of this large species excellent specimens of both sexes are in the collection of the Expedition. 

 It has occasionally been confounded with the Great American Horned Owl of the United States, 

 (Bubo virginianus,') but is clearly distinct, and may always be distinguished from that sjjecies 

 by its much larger and more powerful bill. 



This is one of the largest Owls of western South America, and is rather an uncommon bird 

 near cities in Chile, though occasionally met with in the mountains. 



OTUS BEACHYOTUS, (Forster.) 



Strix hrachyotus, Forst. Phil. Trans. London, LXII_, 1772, 384. 

 Strix Georgica, Lath. Ind. Orn. Supp. I, 1801, 15. 

 Ulula otus, Gay, Fauna Chilena, Aves, 251. 

 VuLG. Short-eared Oivl. Nuco. 

 Figures. — Wilson, Am. Orn. IV, PI. xxxiii. Fig. 3.
