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

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

 roideus is the female of ;S'. vnlliamsoni. The opposite sexes of each 

 of these species have not been satisfactorily recognized, and upon 

 examination of Mr. Henshaw's material, I tiud 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. vnlliamsoni becoming a syno- 

 nyme. No. 305 is therefore to be cancelled.
