can also rise into a tree by taking a running start and then sail- 
ing on spread wings. They do not attempt any real flight, how- 
ever. Their food includes lizards, snakes, grasshoppers, beetles, 
etc.” 
456, $ ad!. Camp Lowell, May 31. Length, 23.10; extent, 21.50. 
“Iris dark brown with a narrow light-yellow ring next the pupil ; bill 
dull brownish-black; feet pale bluish; scutella of tarsi dull yellowish; 
bare space on sides of head, dull blue about the eye, whitish for a small 
space behind the eye, and still farther back, red with a yellowish tinge.” 
135. Coccygus americanus (Linn.) Bonap. Yellow- 
billed Cuckoo. 
512, $ ad., Tucson, June 8. Length, 12.60; extent, 17; wing, 6; tail, 
6.57; culmen, 1.13. “Iris brown; legs dark greenish-brown; bare orbi- 
tal space much the color of the surrounding feathers. This is the first 
specimen that I have seen in Arizona.” 
527, $ ad., Tucson, June 12. Length, 12.30; extent, 16.70 ; wing, 5.94 ; 
tail, 6.47; culmen, 1.13. “Two others seen to-day.” 
136. Scops asio trichopsis? ( Wagl.) Brewster . Mexican 
Screech Owl. 
The specimens catalogued below are unmistakably referable 
to the so-called trichopsis * of our South-western border, 
a form which, as I have lately stated, grades into asio through 
the California race bendirii. There is a doubt, however, as to 
whether Mr. Ridgway’s trichopsis is really the trichopsis of 
Wagler, and this question, I believe, still remains unsettled. Mr. 
Henshaw’s Arizona specimens were referred to maccalli , but 
as that race is now restricted, within the United States, to the 
Valley of the Lower Rio Grande, in Texas, they probably belong 
here. 
488, $ ad., Camp Lowell, June 3. Length, 8; extent, 21.20; wing, 
5.52; tail, 3.20. “Iris yellow; bill black, paler at tip ; toes pale. Parent 
of the next.” 
489, $ juv., first plumage, same locality and date. “Shot by moonlight 
among low mesquites. Call-note a kind of chuck, different from anything 
that I have previously heard. There were others, probably the remainder 
of the brood, but after I had shot the parent they remained silent. 
137. Bubo virginianus subarcticus (Hoy) Ridgw. West- 
ern Horned Owl. — The female of the pair mentioned below I 
was shot as she flew from her nest, which was built in a mesquite j 
at a height of about fifteen feet. It contained a recently hatched j 
bird and one addled egg. The latter measures 2.15X1*75-
