falcate outermost feather instead of straight linear parallel-sided rounded-ended ; and under 

 parts less glossed with green. The 9 costm lacks gi-een gloss on under parts, which are 

 more white, has much narrower tail-feathers, and is smaller, in comparison with 9 wwub. 

 The 9 <Mst(B more closely resembles 9 Stelhila calliope, but the latter has traces at least o' 

 rufous on tail and under parts. Also resembles 9 Trochilus, but has all the lateral tail- 

 feathers white-tipped. Arizona and Southern California, and southward.
