 Gcothlypis pldlailclphia. a. macgillivrayi, CouES, B. N.W., 1874, 75. 



Representing the i\Iaryland Yellow-throat in the mountains, this speeies 

 was found in all the fertile canons from the Sierra Nevada to the Uintahs. 

 It inhabited the rank herbage near the streams, or the undergrowth of the 

 thickets and aspen copses. We did not hear the song of this species, but 

 were ver}- familiar with its ordinary note, a strong chip, greatly resembling 

 that of the Indigo-bird, or its western representative {Cijanospka cyanea and 

 C. a.nosmi), the notes of both old and young being alike.
