 Megascops asio cineraceus Ridgway 

 Auk 12 (4) : 390, October 1895. 

 =Otus asio cineraceus (Ridgway) . See Peters, Checklist of birds of the 



world 4: 102, 1940. 

 110912. Adult male. Fort Huachuca, Cochise County, Arizona. Febru- 

 ary 24, 1885. Collected by Harry C. Benson. Original number 284. 

 110914. Adult male. Fort Huachuca, Cochise County, Arizona. April 



4, 1887. Collected by Harry C. Benson. Original number 512. 

 This name is based upon the series erroneously identified as "M [ega- 

 scops], asio trichopsis (Wagl.)" by Ridgway (Manual of North American 

 birds, p. 261, 1887). No type or type locality was mentioned, and the 

 original material included the form later to be named aikeni by Brewster 

 (Auk 8: 139, 1891). 



In 1910 Swarth, in naming O. a. gilmani (Univ. California Publ. Zool. 

 7:1), observed: "In response to a request for information regarding the 

 type locality of cineraceus (which is not indicated . . .), Mr. Ridgway 

 kindly sent me as a topotype a specimen collected at Fort Huachuca, 

 Arizona . . ." 



The specimen sent was No. 110912, which has subsequently been consid- 

 ered the type. Its claim to this distinction seems, however, to have no more 

 validity than that of No. 110914, one of the original series from the same 

 locality; both specimens are therefore here considered equivalent cotypes.
