1 19. lache latirostris {Swains.) Elliot . Broad-billed 
Hummingbird. — From the known fact of its occurrence among 
the Chiricahua Mountains, as ascertained by Mr. Henshaw in 
1874, it was of course to be expected - that this Hummer would 
eventually be found, under similar conditions, in other parts of 
Arizona, a probability which Mr. Stephens has confirmed by 
the capture of five specimens in the Santa Rita Mountains. In 
addition to these, several others were seen at various times dur- 
ing his short stay in that range, and I infer from his notes that the 
birds were not uncommon there. They were always found near 
water, and usually along the streams which flowed through 
canons, high among the mountains. They seemed to prefer syc- 
amores to other trees, and invariably perched on dead twigs 
where they could command an open view. “Their notes were 
flat and differed from those of other Hummers.”

120. Cypselus saxatilis Woodh. White-throated Swift. 
— In some notes made at Cave Creek, under date of March 4, 
Mr. Stephens incidentally refers to this Swift as follows : “We 
camped here last night chiefly for the purpose of investigating 
some caves said to contain large quantities of bird-droppings. I 
j went to one of the largest of these to-day and found the floor 
covered with tons of bat droppings as well as a little from birds. 
There were also a few feathers (primaries and rectrices) of 
Cypselus saxatilis and some of Falco sparverius.” 
121. Antrostomus vociferus arizonae Brewster. Steph- 
ens’ W hip-poor-will. — During 1881 this Whip-poor-will was
