was carried away by the shot. The specimen was obtained at Stoctou, 

 July, 1877. 



38. Contopus richardsonl. No. 73,547. No date. 



39. Empidonax pusillus. No. 73,044. Stocton, July, 1877. 



40. Empidonax obscurus. No. 73,047. Murphy's, April 28, 1878. 



41. Empidonax hammondi. Nos. 73,045-6. Murphy's, April 28, 

 1878. 



42. Picus nuttalli. No. 73,033. Murphy's, Calaveras County (alt. 

 2,000 feet), April, 1877. 



43. Picus pubescens. An adult male (No. 73,606), collected Decem- 

 ber 27, 1877, is absolutely typical P. pubescens. There is a large cluster 

 of white sjiots covering the lesser wing-covert region, while the gi-eater 

 coverts have a row of white spots at the base, more or less concealed by 

 the middle coverts ; the secondaries and tertials are likewise completely 

 crossed by bands of white spots. I have seen very many Western exam- 

 ples of this bird approaching the true pubescens, to a greater or less 

 degree, but this is the first I have seen having the row of spots at the base 

 of the greater coverts, and the conspicuous cluster of white spots, forming 

 an irregular broken patch on the middle coverts, — the essential charac- 

 ters of pubescens, as restricted.

 This series is one of great interest. One specimen corresponds very nearly 

 to 0. " ayresii " of Audubon, having red " mustaches," gray throat, and 

 yellow shafts ; the latter, however, have a decided orange cast, while there 

 is merely a trace of the scarlet occipital crescent. The most interesting 

 specimen of all, however, is No. — , of which, unfortunately, the tail 

 only was sent. In this the rectrices are deep red, as in true mexicanus, 

 with the exception of the middle paii", which are pure gamboge-yellow, 

 without a trace of orange ; the contrast being thus very striking. An- 

 other specimen, of which the tail only was sent, is similar except that the 

 middle tail-feathers are pale-pinkish instead of yellow. 



Records of the occurrence on the Pacific Slope of species formerly con- 

 sidered exclusively Eastern, have now become so numerous as to render 

 it extremely probable that, as the various districts of our Western domain 

 are more fully explored, the number of species common to both sides of 

 the continent will be considerably increased and the list of those peculiar 

 to the Eastern Province correspondingly diminished. The transfer from 

 the latter category to the former may be considered as established with 

 regard to several of the species enumerated above, as Dendraca coronata,
