This Vireo although av^eraging considerably smaller than V. 

 s. cassinil has a bill as large and stout as in V. s. alticola. In 

 the coloring of the upper parts all my spring and summer speci- 

 mens agree closely with cassinii but there is a decided and very con- 

 stant diflerence in the color of the flanks and sides, these having 

 quite as much yellow as, but much less greenish than, V. solita- 

 riiis. In autumnal plumage the Lower California bird approaches 

 autumnal specimens of solitarius very closely, having the upper 

 parts quite as bright olive green, the wing-bands as yellow, and 

 the head nearly as clear ashy. There is also fully as much yellow 

 on the sides, but much less greenish. These characteristics, with 

 the almost total lack of brownish beneath, distinguish it readily 

 from yoiuig cassinii. 



* The wings and tail of this specimen are considerably worn.
