132 EXPLORATIONS AND SURVEYS WEST OF 100TH MERIDIAN. 



124. Selasplwrus platycercus, (Sw.) Broad-tailed Hummingbird. 



Found at same time and in same localities as the preceding, but not 

 nearly so abundant. It is, however, very numerous, and in certain local- 

 ities, as at Inscription Eock, exceeded the Kufous-backed in numbers. 

 Like it, seems to frequent no especial locality, but follows the range of 

 the flowers everywhere. 



125. Eugenes fulgens, (Sw.) 



SP. CHAR. Male : tail rather deeply emarginated ; head above 

 violet purple ; rest of upper parts bronzed green, becoming pure bronze 

 on the tail ; gorget brilliant emerald- green, with strong purple reflec- 

 tions ; lower portion of breast and abdomen opaque black, more 

 velvety toward the green of throat ; sides of body dull green ; wing 

 above and below dull purple; upper and lower wing-coverts green; 

 crissurn pale brownish-gray; bill and feet black. Female: tail double- 

 rounded, above dark metallic-green, each feather edged with ash r 

 below dull white ; feathers of throat and fore part of breast with dull 

 grayish-green centers ; sides green, edged with ash ; wing dull purple ; 

 each feather of the tail except the two central, which are green through- 

 out, with broad purple band ; three outer tail-feathers broadly tipped 

 with dull white, which, on the outer, extends slightly further up on the 

 outer web. Length, 4.61 ; wing, 2.43 ; tail, 1.75 ; bill, 1.09. 



This fine species is now for the first time introduced into our fauna, 

 it never having been before observed farther north than the table lands 

 of Central Mexico. A female was taken on a small stream issuing from 

 the mountains, at Camp Grant, Ariz., September 24, and identified 

 by Mr. G. N. Lawrence as of this species. When first seen, it was being 

 pursued by another hummer, of which I obtained but a glimpse as 

 they darted past through the trees, but I have little doubt that it was 

 a second of the same species. I think it not unlikely that the species 

 will be found to be not uncommon in the mountainous districts of South- 

 ern Arizona and New Mexico. 



CucuLiD^a (the Cuckoos). 



126. Geoccocyx calif ornianus, (Lesson.) Koad-Bunner; Chaparral-Cock. 

 From information obtained from hunters and guides, this remarkable 



bird seems to be rather common and generally distributed through the 

 valley of the Gila and southward. It is of retiring habits, and, as it 

 keeps in the chaparral and thickets, is very likely to be overlooked. I 

 secured one of these birds on the Gila in October. It was sitting 

 quietly on a stump, sunning itself in the rays of the rising sun, and 

 had allowed several pack-mules to pass within twenty feet without
