425. Micropus melanoleucus (Baird). This becomes 



Aeronautes melanoleucus (Baird). 



{Cf. Hartert, Cat. Birds Brit. Mus. XVI, 1S92, 459. 

 Aeronautes Hartert, gen. nov. ; type, Cypselus melanoleucus 

 Baird.) 



It was decided to recognize Calypte Gould, Selasphorus 

 Swainson, Stellula Gould, and Calothorax Gray, as full 

 genera instead of as merely subgenera of Trochilus Linn. This 

 decision disposes of the question of Trochilus Jloresii Gould 

 (186 1, nee Trochilus Jloresii Bourctek, 1846) vs. Trochilus 

 rubromitratus Ridgway. ( Cf. Ridgway, Auk, VIII, Jan. 

 1S91, 114.) The species of Hummingbirds numbered 430 to 

 437, inclusive, will hence stand as follows : — 



430. Calypte costse (Bourc). 



431. Calypte anna (Less.). 



43 1 . 1 . Selasphorus floresii (Gould) . 



432. Selasphorus platycercus (Swains.). 



433. Selasphorus rufus (Gmel.). 



434. Selasphorus alleni Hensh. 

 436. x Stellula calliope (Gould). 

 437. Calothorax lucifer (Swains.). 



III. FORMS CONSIDERED AS NOT ENTITLED TO 



RECOGNITION. 



Vireo vicinior californicus Stephens, Auk, VII, April 

 1890, 159. Not admitted on account of the insufficiency of char- 

 acters alleged. 



IV. PROPOSED CHANGES OF NOMENCLATURE 



REJECTED. 



Columbigallina purpurea Maynard (Am. Exch. and Mart., 

 Ill, 1887, 33) vs. Columbigallina passerina (Linn.). ( Cf. 

 Berlepsch, Journ. f. Orn. 1S92, 97.) Rejected on the ground 

 that the hypothetical case upon which the name purpurea was 

 tentatively pi-oposed proves to be without foundation. 



1 No. 435, Trochilus heloisa, has been eliminated. {Cf. Auk, VIII, Jan. 1891, 88.)
