THE HUMMING BIRDS. 325 



green, the feathers showing narrow and indistinct paler margins ; upper 

 tail-coverts similar, but much darker; tail black, faintly glossed with 

 dull blue, the three outer feathers broadly tipped with white, this broad- 

 est (about .70 of an inch) on outer web of exterior feather ; remiges dull 

 brownish slaty, very faintly glossed with purplish. A white streak 

 behind eye, above upper margin of ear-coverts, the latter dusky; this 

 color extending beneath eye to, and including, lores ; beneath the latter, 

 a buffy, or rusty- whitish rictal streak extends as far back as beneath 

 middle of eye. A large patch, with convex posterior outline, covering 

 chin and whole throat, metallic cobalt-blue, each feather narrowly mar- 

 gined with pale brownish gray these edgings very conspicuous in 

 certain lights and causing a scale-like appearance ; rest of under parts 

 dull brownish gray, the lateral portions glossed with bronze-green, and 

 under tail-coverts broadly margined with white ; downy femoral tufts 

 ^lull white. Bill entirely black. ^ Length (skin), 5.00* ; wing, 3.15; tail, 

 2.20 (middle feathers 2.00) ; exposed culmen, .92. 



Adult female (No. 35159, Mirador; Dr. 0. Sartorius) : Similar to the 

 adult male, but chin and throat dull brownish gray, similar to but a 

 little paler than the color of the breast, etc. Length (skin), 4.40; 

 wing, 2.80; tail, 1.90; exposed culrnen, 1.00. 



This large and rather dull-colored^species of Humming Bird, named 

 in honor of Madame Clemence Lesson, was first added to the United 

 States fauna by Mr. F. Stephens, who on May 14, 1884, took an adult 

 male in the Santa Catalina Mountains, near Camp Lowell, Arizona, as 

 recorded by Mr. William Brewster, in The Auk, January, 1885, p. 85.t 

 It has since been taken in various localities in the southern part'of that 

 Territory by different collectors (among whom may be named Mr. Will. 

 W. Price and Mr. Otho C. Poling), but so far as we are aware nothing 

 has been published by them regarding its habits. 



Mr. Gould says that he believes the true and restricted habitat of 

 this species to be the moderately high table-land of Mexico, and he 

 adds that, "it is a large and powerful bird . .- . distinguished for 

 the quietness of its coloring rather than for any of those brilliant 

 metallic markings so prevalent among humming birds in general."

* The measurements before skinning of a male taken at Camp Lowell, Arizona, by 

 Mr. F. Stephens, were as follows: Length, 5.40; extent, 7.50 ; wing, 3.10; tail, 1.91; 

 culoieu from nostril, .88. A skin collected in the Huachuca Mountains, Arizona, by 

 Mr. Will W. Price, measures as follows: Length, 5.00 ; wing, 3.10; tail, 2.00; ex- 

 posed culmen, .85. 



t The locality was first given as Camp Lowell, but this was subsequently corrected 

 (The Auk, April, 1885, p. 199).
