No. 274bis. A fine species of humming bird has been discovered by 

 Mr. H. W. Henshaw to inhabit Arizona, and has been determined 

 by Mr. Lawrence to be Eugenes fulyens. (Am. Nat., viii, 1874, in 

 press.) 



274bis. EUGENES FULGEWS (Sw.). 

 Refiilgreiit II manning l>ii-l. 



No. 279. The authority is (LESS.) BP. 



" 281. The authorit3 r is (LESS.) GLD. 



" 292. The authority is (LATH.) NUTT. 



" 303? This species, queried in the text, and in Key, p. 195, may 

 be regarded as a variety of 302, the intergradatiou, through 302a, prov- 

 ing complete. See Ridgway, Am. Jour., iv, Dec., 1872. 



302b. SPHYBAPICUS VARIUS (L.) BD., 



var. RUBER (Gm.) Kidg. 

 Red-breasted Woodpecker. 



Nos. 304, 305. Observations lately made by Mr. H. W. Henshaw 

 (Am. Nat., viii, 1874, in press) are to the effect that Sphyrapicus thy- 

 roideus is the female of S. williamsoni. The opposite sexes of each 

 of these species have not been satisfactorily recognized, and upon 

 examination of Mr. Henshaw's material, I find almost conclusive evi- 

 dences in favor of his views, substantiating his observations. Such 

 sexual differences are unique in the family. As the older name, K. 

 tliyroideus will stand for the species, 8. williamsoni becoming a syno- 

 nyrae. No. 305 is therefore to be cancelled. 



No. 307. The authority is (WAGL.) GRAY.
