425. Micropus melanoleucus (Bairp). This becomes 
Aéronautes melanoleucus (Bairp). 
(Cf. Hartert, Cat. Birds Brit. Mus. XVI, 1892, 459. 
Aéronautes HARTERT, gen. nov.; type, Cypselus melanoleucus 
BaIrRD.) 
It was decided to recognize Calypfte GouLp, Selasphorus 
Swainson, Stellula Gouip, and Calothorax Gray, as full 
genera instead of as merely subgenera of 7rochilus Linn. This 
decision disposes of the question of Zrochilus florestt GouLp 
(1861, zec Trochilus florest? BourcitEr, 1846) vs. Trochilus 
rubromitratus RipGway. (Cf. Ripeway, Auk, VIII, Jan. 
1891, 114.) The species of Hummingbirds numbered 430 to 
437, inclusive, will hence stand as follows :— 
430. Calypte costz (Bourc.). 
431. Calypte anna (LEss.). 
431.1. Selasphorus floresii (GouLp). 
432. Selasphorus platycercus (Swains.). 
433: Selasphorus rufus (GmMeEt.). 
434. Selasphorus alleni Hensu. 
436.' Stellula calliope (GouLp). 
437. Calothorax lucifer (Swains.). 
III. FORMS CONSIDERED AS NOT ENTITLED TO 
RECOGNITION. 
Vireo vicintor 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., 
III, 1887, 33) vs. Columbigallina passerina (LINN.). (Cf. 
Brervepscu, Journ. f. Orn. 1892, 97.) Rejected on the ground 
that the hypothetical case upon which the name purpurea was 
tentatively proposed proves to be without foundation. 
1 No. 435, Trochilus heloisa, has been eliminated, (Cf. Auk, VIII, Jan. 1891, 88.)
