exploration of the western coast and southern extremity of Lower California, 

 in the interests of the National Museum, a considerable portion of his time 

 being spent at La Paz, on the eastern side of the peninsula. Among the birds 

 obtained at this locality was a single example of S winhoe's wagtail (ikfotociZZa 

 ocularis), a species belonging to eastern Asia, so that the individual in ques- 

 tion must in all probability have crossed the Pacific Ocean, perhaps aided 

 by some vessel bound toward our shores. The other, a Mexican species, the 

 chestnut-headed yellow warbler, {Dendroeca bryanti), first described in 1874, 

 Mr. Beldiug found to be a common inhabitant of the mangrove thickets skirt- 

 ing the Gulf shore.
