Oil the 29th of August, 1868, a single individual of this strongly-marked 

 species was seen in the lower portion of one of the eastern canons of the 

 East Humboldt Mountains. It was busily engaged in searching for its 

 insect food, in a thicket along the stream, during which occupation it uttered 

 an occasional note, sounding like a lisped and faint enunciation of pzeet.

This Warbler, like the T). oceuh'iifcdis, was exceedingly rare along our 

 route, only one other specimen besides that obtained having been seen. 

 The one in question was observed on the 8th of September, in an alder- 

 thicket high up one of the eastern canons of the East Humboldt Mountains. 

 The manners and notes of this species, iis observed at this season, seemed 

 much like those of D. occidentalis, neither possessing any strikingly distinctive 

 trait, so far as could be observed.
