28 Bangs, Birds of San Miguel Island. [^^"J' 



mingbird is based are in fine plumage, showing no sign of wear. 

 They differ so much in the shade of green of the back and tail, 

 as well as in the greatly reduced amount of buffy edgings of the 

 plumage above from all examples of P. afithophilus that I have 

 seen, that I do not hesitate to give the form a name. Whether or 

 not it is an island form, confined to San Miguel, I am unable to 

 say. I, however, can not find that P. anthophilus has ever been 

 recorded from so far north as Panama. 



Amizillis edwardi {Delattre d- Botircier). — Nine adults, both sexes, 

 April and Mav. 



Chlorostilbon assimilis Laivr. — Seven adults, six males, one female, 

 April and May. 



Mionectes oleagineus {Lickt.). — Two specimens, a pair, taken April 

 20. These examples agree exactly in color with South American speci- 

 mens and not with the form I have lately described from Loma del Leon, 

 Panama.' The wings are, however, a little short for true oleagitteus and 

 a little long for parens. 



Ornithion pusillum {^Cab. d- Heine). — Two males, April 29 and May 

 4. These are in bad plumage and are just beginning to moult. They 

 are very dark, especially on the back, but this dull coloring is probably 

 due to the condition of the feathers, as otherwise they are perfectly refer- 

 able tq true pusillum. 



Elaenia pagana subpagana Scl. d Salz>. — Four males in worn, faded 

 plumage, April and May, and one young in nestling plumage, May 2. 



Elaenia sordidata,- sp. nov. 



Fourteen specimens, adults of both sexes — many in worn faded plum- 

 age, others in fairly good plumage — April and May.
