392 Fourteenth Supplement to the A, O. U. Check-List. Fue 
Tympanuchus vs. Bonasa (c}. StoNE, Auk, 1907, 198). Proposed 
change rejected, for reasons given under the preceding case. 
315. Ectopistes migratorius vs. L. macroura (cf. Banas, Proc. 
Biol. Soc. Wash., XIX, 1906, 44). Not adopted, the pro- 
posed change, in the opinion of the Committee, being based on 
false reasoning (see ‘Changes in Nomenclature,’ under No. 
316). 
Cathartes vs. Rhinogryphus (cj. Strong, Auk, 1907, 198). Pro- 
posed change based on the “first species” rule, hence not accepted. 
Tachytriorchis vs. full genus (cj. Twelfth Supplement, Auk, 
1903, 368). The proposed change in status considered unnecessary. 
Hierofalco vs. full genus (cj. Twelfth Supplement, Auk, 1903, 
368). The requirements of this case are believed to be fully met 
by retaining [7ierojalco as a subgenus. 
Rhynchofalco vs. [7ypotriorchis, and as full genus (¢/. DuBots, 
Syn. Avium, 1902, 872). Not considered worthy of generic rank, 
and Hypotriorchis and Rhynchojalco are deemed to be subgener- 
ically distinct. 
Asio vs. Nyctalops (cj. Sronr, Auk, 1903, 275). No change 
required. 
Psiloscops (cj. Cours, Osprey, III, 1899, 144). Not accepted, 
the proposed subgenus possessing no characters worthy of recogni- 
tion. 
Bubo vs. Asio (c}. Sronr, Auk, 1903, 275). No change required.

375. Bubo virginianus vs. Asio [= Bubo] magellanicus virgin- 
ianus (c}. OBERHOLSER, Proc. U.S. Nat. Mus., XX VII, 1904, 
179, 188). No change required, as Stria magellanicus proves 
not to have been used in a systematic sense by Gmelin.
