Sp. Char. Largest of North American .species of Hiiraming-Bird. Tail deeply forked; 

 external feather narrow, linear. Top of the head, throat, and a moderate ruff, metallic 



crimson-red, with purple reflections. Rest of 

 upper parts and a band across the breast green. 

 Tail-feathers purplish-brown, darkest centrally. In 

 the female the tail is slightly rounded, not emargi- 

 nate ; the scales of the head and throat are want- 

 ing. Tail barred with black, and tipped with white. 

 Length, about 3.60; wing, 2.00; tail, 1.45. 

 Hab. Mexico and coast region of Cahfornia. 



The C. florcsi of the taltle-lands of 

 Mexico resembles this species in every 

 respect except the tail, which is some- 

 what like that of Sc/csphorus riifus. The 

 only Xorth American species to which the 

 male of this bird liears any resemblance is the A. costce, which has the same 

 metallic crown and other generic features. The latter, however, is much 

 smaller ; has the metallic reflections varied, 

 cliieily violet, instead of nearly uniform pur- 

 plish-red. The tail is much less deeply forked, 

 the depth being only about .10 of an inch, in- 

 stead of .32 ; the outer feather is much nar- 

 rower. The females of the two, liowever, 

 appear to be distinguishable only l>y their 

 relative size. Tlie aliscnce of rufous, and the 

 rounded, not graduated, tail always separates the female of anna from that 

 of Selasplwrus ru/ux. The larger size is the chief distinction from the 

 female Calypte costw, while the size and less acutely pointed outer tail- 

 feathers distinguish it from tlie female Trochilus coliAris. 



We have never seen any specimens of this bird taken out of California, 

 nor quoted of late years as occurring in Mexico, although stated by Gould to 

 belong to the table-lands. 



Habits. This beautiful Humming-Bird is found from the high table- 

 lands of ]\Iexico throughout tlie western portions of that region, and through 



Calypte anna.
