204 Proposed Changes in the A. O. U. Check-List. [i^rii 



Branta bernicla glaucogastra (Brehm) becomes Branta bernicla 



(Linnaeus); since Branta bernicla glaucogastra is only a dimorphic 

 variety. Furthermore, Bernicla glaucogaster Brehm (Handb. Naturg. 

 Vog. Deutschl., 1831, p. 849) applies to the form now called Branta 

 bernicla bernicla; so that were the race now known as Branta bernicla 

 glaucogastra recognizable as a subspecies it would have to stand as 

 Branta bernicla collaris (Brehm) {Bernicla collaris Brehm, Handb. 

 Naturg. Vog. Deutschl., 1831, p. 851; Coasts of Pomerania). (Of. 

 Hartert, Scottish Naturalist, No. 64, April, 1917, pp. 75-76.) 

 Ardea herodias occidentalis Audubon becomes Ardea occidentalis 

 Audubon, because considered a distinct species. (Cf. Bartsch, 

 The Auk, XXXIV, No. 1, Jan., 1917, p. 86.) 



t Ardea herodias wardi Ridgway. Reinstated as a tenable subspecies, 

 because considered specifically distinct from Ardea occidentalis Audu- 

 bon. (Cf. Todd, Annals Carnegie Mus., X, Jan., 1916, pp. 177-178; 

 Bartsch, The Auk, XXXIV, No. 1, Jan., 1917, p. 86.) 

 Egretta candidissima (Gmelin) becomes Egretta thula thula (Molina). 

 Ardea thula Molina, Sagg. Stor. Nat. Chili, 1782, p. 235 (Chile). 

 The North American races will therefore need to be called : 

 Egretta thula thula (Molina). 

 Egretta thula brewsteri Thayer and Bangs. 



tLimnogeranus Sharpe, Bull. Brit. Orn. Club, I, No. VII, 1893, p. xxxvii 

 (type, Ardea americana Linnaeus). Recognized as a genus to include 

 Grus americana (Linnaeus). (Cf. Brasil, Genera Avium, XIX, 1913, 

 p. 4), which therefore becomes: 



Limnogeranus americanus (Linnaeus). 

 Grus mexicana (Muller) becomes Grus canadensis mexicana 

 (Muller). (Cf. Brasil, Genera Avium, XIX, 1913, p. 4.) 



fEroliinse. Recognized as a subfamily of Scolopacidse for genera allied 

 to Pelidna. (Cf. Lowe, Ibis, 1915, pp. 609-616.) 



fTringinee. Recognized as a subfamily of Scolopacidae for genera allied 



to Totanus. (Cf. Lowe, Ibis, 1915, pp. 609-616.) 

 Pisobia damacensis (Horsfield) becomes Pisobia minutilla sub- 

 minuta (Middendorff) (Tringa subminuta Middendorff, Reis. Siber., 

 Zool., 1851, p. 222; western slope of Stanovoi Mts., and Uda 

 River, southeastern Siberia), since it is a subspecies of Pisobia minu- 

 tilla, and since the name (Pisobia damacensis) Horsfield is a synonym 

 of Pisobia ruficollis (Pallas) and thus unavailable for the bird now 

 known as Pisobia damacensis. (Cf. Hartert, Novit. Zool., XXIII, 

 1916, pp. 92-93.) 



fErolia ferruginea chinensis (Gray). Tringa (Pelidna) chinensis Gray, 

 Zool. Miscell., 1831, p. 2 (China). Alaskan records of this species 

 belong under this newly recognized subspecies. (Cf. Mathews, Birds 

 of Australia, III, pt. 3, Aug. 18, 1913, pp. 266-268.) 



fVetola Mathews. New genus. Mathews, Birds Australia, III, pt. 2, 

 May 2, 1913, p. 191 (type, Scolopax lapponica Linnaeus). Includes 

 the following North American species how in the genus Limosa:
