XANTUS'S HUMMINGBIRD. 227 



was })liiced underneath an awniny or shad(^ of l)on;:>lis and weeds in front of a 

 farmhouse. It was surrounded by downy heads of coniposite phmts, and coukl 

 scarcely be distinguished from them, liavin^-, as usual, been made of raw cotton." 



This ntist, which is now before me (No. 18563, United States National 

 Museum collection) is composed exteriorly of fine plant fibers, thistle down, and 

 shreds of moss, and these are securely fastened into place by spider weljs ; the 

 interior is lined with thistle down and I'aw cotton; it measures about 1| inches 

 in outer diameter by 1 inch in height. The inner cavity is large for the size of 

 the nest, measuring 1 inch in width l)y one-half incli in depth. The second 

 nest, No. 185G4, taken by Mr. Belding on May 7, 1SS2, in a canyon near 

 Santiago Peak, Lower California, resembles the nest of the Black-chinned 

 Hummingbird somewhat, being principally composed of plant down, covered 

 on the outside with a few scales of buds, seed capsules, fine shreds of bark fiber, 

 leaf stems, and an empty cocoon, and these decorations are fastened with spider 

 webs, while the inner cup is lined with plant down and other fine fibroixs material. 

 This nest was saddled on the fork of a small twig. Its dimensions are about 

 the same as those of the first nest describeil, and like it is rather sliallow. 



The eggs resemljle those of our better-known Ilummingliirds in shape and 

 color. The two taken from the first nest measure respectively 12.19 by 7.87 and 

 11.94 by 7.87 millimetres, or 0.48 by 0.31 and 0.47 by 0.31 inch; and those of 

 the second nest, 11.94 by 8.13 and 12.19 by 7.87 millimetres, or 0.47 by 0.32 

 and 0.48 by 0.31 inch. 



Tlie type specimen. No. 18564 (not figured), from a set of two eggs, was 

 taken by Mr. L. Belding on May 7, 1882, near Santiago Peak, Lower Califi)i-nia, 

 as already stated.

This handsome Hummingbird has only very recently been added to our 

 fauna, Dr. A. K. Fisher obtaining a specimen on June 9, 1894, in the Chiricahua 

 Mountains, in southeastern Arizona. In writing of this ca])ture he says: 



"During the early part of June a camp was made at Fly Park, a well- 

 wooded area southeast of the head of Pinery Can}'on, at an altitude of about 

 10,000 feet. A boreal honeysuckle (Lonicera involiicraid) grows commonly 

 through the scattered woods of sjjruce (Picea engelmanm), fir (Pseii(Jnisiif/a taxi- 

 folia), pine (riiius ayacalmite), and aspen (PopuJus frciiiiiloidcs). Tlui flowers of 

 the honeysuckle attract great numbers of Ilunnnei-s, and lumdreds of Selas-
