422 Thirteenth Supplement to the A. O. U. Check-List. fly 
Icterus spurius affinis (LAWRENCE) (cf Cougs, Key, 1903, 
477): 
This is considered inseparable from /. sfurius and not worthy 
of recognition. 
Genus ASTRAGALINUS Casanis vs. Acanthis (cf. HARTERT, 
Vig. Pal. Fauna, 1903, 66). In the opinion of the Com- 
mittee Astragalinus is sufficiently distinct generically from 
Acanthis, 
Centronyx, subgenus of Cofurniculus, vs. Centronyx, sub- 
genus of Passerculus (of. CouEs, Key, 1903, 403). The 
question of the status of Ceztronyx was carefully considered 
by the Committee last year (cf Twelfth Supplement, Auk, 
1903, 349), and no change appears to be necessary. 
GEeNusS COTURNICULUS Bonaparte vs. Coturniculus, sub- 
genus of Ammodramus (cf. Coues, Key, 1903, 403, 408). 
The status of Cofurnicu/us was also decided at a recent meet- 
ing of the Committee (c% Twelfth Supplement, Auk, 1903, 
349). 
Genus OREOSPIZA Ripceway vs. Chlorura (cf. PocuE, Ornith. 
Monatsb., 1904, 25-26). There is no necessity for a change, 
as Chlorura Sclater is preoccupied by Ch/orurus Swainson. 
5887. Pipilo maculatus atratus Ripcway vs. /. m. megalonyx 
(cf, GRINNELL, Condor, 1902, 23). No change is deemed 
advisable in this case. 
Subgenus Aveneria BONAPARTE (cf. COUES, Key, 1903, 460). 
This is used by the late Dr. Coues as a subgenus for the 
Brown ‘Towhees, but is properly a synonym of the extralimital 
genus JZe/ozone, and as such does not require consideration 
here. 
Genus Chrysocantor MAYNARD (cf. BANGs, Bull. Mus. Comp. Zodl., 
XXXIX, 1903, 153). This is rejected as being based upon 
color characters alone.
