III. FORMS CONSIDERED AS NOT ENTITLED TO 

 RECOGNITION. 



Megascops asio sat?tratus Brewst., Auk, VIII, April, 1S91, 

 141. 



Considered as a synonym of Megascops asio ke?inlcottii 

 (Elliot), the range of variation in a large series of specimens 

 of M. a. sat ur at us covering all of the alleged distinctive 

 features of the supposed unique type of M. a. ke7inicottii, the 

 range of which latter is now extended southward over the sup- 

 posed habitat of AT. a. saturatus. 



Parus hudsonicus ungava Rhoads, Auk, X, Oct., 1S93, 328. 



Considered as not separable from Parus hudsonicus Forst., 

 owing to the insufficiency of the alleged characters. It was 

 tentatively proposed, and confessedly without comparison with 

 specimens of P. hudsonicus from any point near the type locality 

 of the species. 



Parus hudsonicus cvura Coues (Key N. Am. Birds, 1SS4, 

 267). (Cf. Rhoads, Auk, X, Oct., 1S93, 331.) 



Considered as inseparable from Parus hudsonicus Forst. 



IV. PROPOSED CHANGES OF NOMENCLATURE 



REJECTED. 



Conuropsis vs. Conurus, and hence Conuropsis caroiinensis 

 vs. Conurus caroiinensis. ( Cf. Salvadori, Cat. Birds Brit. 

 Mus. XX, 1S91, 203.) 



The type of Conurus (Lesson ex Kuhl) is considered to be 

 Psittacus caroiinensis Gm., as originally determined by the 

 A. O. U. Committee by the principle of elimination {cf. Canon 

 XXIV, A. O. U. Code of Nomenclature). Contiropsis Salva- 

 dori, based on this species, becomes therefore a synonym of 

 Conurus.
