NEW BIRDS FROM LOWER CALIFORNIA,

parts white. Oater three rectrices white, third edged with 

 dusky. Iris, hazle. 



I take great pleasure in iiamiug this excellent species for 

 my friend, Mr. Chas. H. Townsend, of the U. S. S. Albatross, 

 as a slight recognition of the much valuable work he has 

 done for western ornithology. 



J. townsendi is probably the most abundant bird to be 

 found in the timbered parts of the San Pedro Mountain, 

 and is, I think, resident, as I have never, with a single ex- 

 ception, taken the species at the base of the range. The 

 characters described are remarkably constant. No. 2540, 

 a fine adult male, sports the abnormal passerine number of 

 thirteen rectrices, and has evidently lost a fourteenth. J. 

 h. oregonus occurs along the base of the range in winter, 

 but does not seem to join J. townsendi in nesting in the 



high altitudes.
