2A.A. Oberholser, Forms of Vermivora celata. I July 



Geographical distribution. — Mountains of New Mexico, Arizona, and 

 southeastern California, to British Columbia ; in migration east to Min- 

 nesota and Pennsylvania, south to Texas, and Mexico to Lower Cali- 

 fornia, Michoacan, Guerrero, and Puebla. 



This new form has usually been included with V. celata celata, 

 but breeding specimens recently obtained, principally from New 

 Mexico and British Columbia, indicate its much closer relationship, 

 in all respects except size, with the west coast forms. From Ver- 

 mivora celata lutescens it may, however, readily be distinguished by 

 its duller, less yellowish color, both above and below, and by its 

 much greater size.
