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 8. williamsoni. The opposite sexes of each 

 of these species have not been satisfactorily recognized, and upon 

 examination of Mr. Hensliaw'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, S. 

 thyroideus will stand for the species, S. williamsoni becoming a syno- 

 nyme. No. 305 is therefore to be cancelled.
