*>. asio. The latter species is doubtless distributed throughout the Territory. 

 I have not personally met with it. Dr. Kennedy procured MeCalli on the 

 Colorado Chiquito River. It is therefore to be enumerated among the Whipple 

 birds. 



32. Otus Wilson-anus (Lesson.) 



Sparsely distributed throughout the Territory. Colorado Chiquito, Ren- 

 tier I ' y. 



33. Brachyotps Cassini Brewer. 



Common throughout the Territory. I saw a surprising number on differ- 

 ent occasions along the Colorado River, in the day time. 



:?4. Nyctale acadica (Gm.) Bonap. 



The known range of this little Owl includes Arizona ; though I have not 

 seen specimens from within the limits of the Territory. 



In addition to the preceding Strigides a species of Athene occurs in Arizona : 

 but whether h ypogea or cnnicularia I cannot now determine positively. The 

 Syrnium occidentale Xantus, (Pr. A. N. S., Ph. 1S59, type from Fort Te.jon) 

 will very probably be found in the Colorado Valley. Dr. Cooper has obtained 

 Nyctale albifrons on the Sierra Nevada of California, which causes Arizona to 

 fail within its now known range.

Planches Color. No. 344, which is South American, and probably the 



same as S. infuscata Temm.)

 Glaucidium infuscatum, Cassin, Birds Cal. and Texas, 1853, i. p. 139. 

 (Name from Strix infuscata Temm., Man. Orn. 1820, i. p. 97 ; which 

 is S. Amer. species, probably the same as passerinoides Temm.) 

 Glaucidium californicum, Sclater. P. Z. S., 1857, p. 4; in text ; pro- 

 posing name if N. Am. species is not true gnoma Wagl. 

 My numerous specimens present no material discrepancies from Wagler's 

 original description in the Isis. I think it far best, with our present informa- 

 tion on the subject, to refer the Oregonian, Californian and Arizonian bird to 

 this species of Wagler, as Mr. Cassin has done. Should the Mexican bird 

 ever be found to differ from the North American, the latter is to be called G. 

 californicum after Sclater, as above quoted. 



My citations of Audubon's and Cassin's works, (ut supra) all refer to the 

 North American bird, though these authors erred in applying to it either of 

 the names infuscatum or passerinoides, both of which refer to South American 

 species, in all probability identical with each other, and quite distinct from 

 our bird. Mr. Cassin himself corrects his error in the " Birds of North 

 America; " and with this gentleman's later views of the synonymy I entirely 

 agree. 



The sexes of this little Owl differ much in size. A male before me measures 

 only 5 "50 X 14*50, but the tail feathers are quite imperfect ; had they grown 

 out fully the bird's lens;th would have been about 7.00. The female is larger, 

 measuring 7*50 X 15-25. The male is rather darker colored than the female : 

 t lie spots above more numerous and smaller; the imperfect nuchal collar of 

 black and white much better defined than in the other sex, where it is almost 

 obsolete. In both sexes ihe iris is bright yellow ; the mouth light purplish 

 flesh ; the bill, cere and feet light greenish yellow ; the soles chrome yellow ; 

 the claws black.
