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

 parts less glossed with green. The 9 costx lacks green gloss on under parts, which are 

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

 rufous on tail and under jiarts. Also resembles 9 Trochilus, but lias all the lateral taiL- 

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