388 CHECK-LIST OF NORTH AMERICAN BIRDS. 



Amizilis Gray, 1840, becomes AmnzUia Lesson, 1843. 



The type of the former proves to be Cynanthus latirostris Swainson which 

 makes it a synonym of Cynanthus and Amazilia as the earUest name for 

 the present genus takes its place. (Cf. Stone, Proc. Acad. Nat. Sci. 

 Phila., 1918, 256.) (p. 183) 



Amazilis cerviniventris chalconota Oberholser, 1898, becomes A. yucatanensis 

 chalconota. 

 A. cerviniventris and yucatanensis are now considered only subspecifically 

 different and the latter being the prior name all the races become sub- 

 species of it. (Cf. Ridgway, Bull. U. 8. Nat. Mus., No. 50, Ft. V, Nov. 

 29,1911,415.) (p. 183) 



Uranomitra has been combined with Amazilia. (p. 183) 



Basillina has been combined with H ylocharis. (p. 183) 



Cola-ptes cafer saluratior Ridgway becomes C. c. cafer (Gmelin), 1788. 



It has been determined that the type specimen of cafer came from Nootka 

 Sound, Vancouver Island, and not from Mexico as supposed, so that the 

 name replaces the nmch later saturatior. (Cf. Palmer, Auk, XXXIII, 

 1916, 322.) (p. 187) 



Pldoeotomus has been combined with Ceophloeus. (p. 189) 



Melanerpes has been divided and M. formicivorus and its subspecies referred 

 to Balanosphyra. (p. 191) 



Sphyrapicus ruber nolkensis (SucKOw), 1800, becomes S. varius ruber (Gmelin), 

 1788. 



Sphyrapicus ruber ruber " (Gmelin) " becomes S. varius daggetti Grinnell, 1901 . 

 A similar case to Cohptesc'fer. It is now considered that the type of ruber 

 came from Nootka Sound and the name will therefore replace notkensis 

 of later tlate, while "ruber" of the last edition of the Check-List will 

 become daggetti the earliest name for the southern form. Both become 

 subspecies of varius instead of ruber because these two are now regarded 

 as only subspecifically different and varius is the older name. (Cf. 

 Grinnell, Condor, III, 1901, 12 and Ridgway, Bull. U. S. Nat. Mus., No. 

 50, Pt. VI, April 8, 1914, 282.) (p. 193) 



Dryobates villosus leucomelas (Boddaert), 1783, becomes D. v. seplentrionaUs 



(NUTTALL), 1840. 



The former name proves to be based on a specimen of true mllosus and 

 hence not available for this race for which septentrionalis is the earliest 

 name. (Cf. Oberholser, Proc. U. S. Nat. Mus., XL, June 3, 1911, 604.) 

 (p. 194) 



Dryobates pubescens homorus Cabanis and Heine, 1863, becomes D. p. 

 leucurus (Hartlaub), 1852. 

 On grounds of priority. (Cf. Giinnell, Condor, XXV, 1923, 30.) (p. 197)
