SUMMARY OF CHANGES. 391 



Hylocichla aliciac aliciac (Baird), 185S, becomes H. miyiima aliciae. 



Hylocichla aliciae bicknelli Ridgway, 1882, becomes H. minima minima 

 (Lafresnaye), 1848. 

 The type specimen of minima proves to be Bicknell's Thrush and therefore 

 takes the place of bicknelli of Ridgway by virtue of priority. As it is 

 also a much older name than aliciae of Baird, it replaces that as the specific 

 name of both races. (Cf. Bangs and Penard, Bull. Mus. Comp. Zool., 

 LXIII, 1919, 30.) (p. 259) 



Cyanosylvia succica robusta becomes C. suecica. 



Because by the suppression of the race robusta as equivalent to true 

 suecica the trinomial form becomes unnecessary, (p, 262) 



Polioptila plumbea (Baird), 1854, becomes P. melanura melanura Lawrence, 

 1857. 

 The former name is found to be invalidated by the much earlier plumbea 

 Gmelin, 1788, and the earliest available name for our Plumbeous Gnat- 

 catcher is melanura Lawrence. (Cf. Penard, Auk, XL, 1923, 334.) 

 (p. 265) 



Regulus has been divided and R. calendula and its subspecies referred to 

 Corlhylio. (p. 266) 



Budytes has been combined with Molucilla. (p. 268) 



Lanivireo and Vircosylva have been combined with Vireo. (pp. 276, 277) 



Helinaia Audubon, 1839, becomes Limnolhlyjris Stone, 1914. 



The type of the former proves to be Motacilla vcrmivora Gmelin, which 

 makes it a synonym of Helmitheros Rafinesque, and Linuwthlypis as the 

 earliest available name must replace it. (Cf. Stone, Science, XL, 1914, 

 26.) (p. 280) 



Vermivora ruhricapilla rubricapilla (Wilson), 1812, becomes V.ruficapilla rufi- 

 capilla (Wilson), 1811. 

 Wilson used both names (in the genus Sylvia) for his Nashville Warbler 

 and we adopt the earlier. This was previously rejected on the ground that 

 it was invalidated by the earlier Sylvia ruficapilla Latham, 1790, but the 

 latter proves to be merely a nomenclatural combination and not an original 

 description while the bird so named is not a Vermivora. (Cf. Cooke, 

 Auk, XXIX, 1912, 545.) (p. 283) 



Vermivora rubricapilla guUuralis (Ridgway), 1874, becomes V. ruficapilla 

 ridgwayi van Rossem, 1929. 

 This subspecies also changes its specific name to ruficapilla while the name 

 guUuralis, owing to the merging of OreotJdypis and Vermivora, is now 

 invalidated by the earlier Vermivora (Oreothlypis) gutturalis (Cabanis). 

 (Cf. van Rossem, Proc. Biol. Soc. Wash., XLII, 1929, 179.) (p. 283)
