white; tail-feathers with slight wliitish tips. Below, a paler shade of the color of the upper 

 parts; throat quite whitish; crissum slightly rufescent ; breast aud belly with obscure dark 

 gray spots on the grayish-white grouud ; uo obvious maxillary streaks, but vague speckling 

 on cheeks. Bill black ; feet blackish-brown. Leugth 10.75; bill 1.12 ; wing 4.25; tail 5.00 • 

 tarsus 1.25; middle toe and claw 1.30. 9 snialler; wing 3.75 ; tail 4.50; tarsus 1.20; middle 

 toe and claw 1.12; bill barely 1.00. Although the ditiereuces from the typical form are not 

 easy to express, they are readily appreciable on comparison of specimens. The upper parts 

 are quite similar ; but the under parts, instead of being whitish, with decided spotting of the 

 color of the back, are grayish, tinged with rusty, especially behind, and the spotting is neb- 

 ulous. The white on the ends of the wiug-coverts and tail-feathers is reduced to a minimum 

 or entirely suppressed. The bill is slenderer and apparently more curved. Arizona and 

 Sonora, common, in desert regions. Nest in cactus, mesquite and other bushes; eggs usually 

 3, 1.10 X 0.80, pale greenish-blue profusely dotted with reddish-brown.

 dire's Thrasher. ^ 9 : Bill shorter than head, comparatively stout at base, very acute 

 at tip ; culmen quite convex ; gonys just appreciably concave. Tarsus a little longer than 

 middle toe and claw. 3d aud 4th prima- 

 ries about equal and longest, 5th and 6th 

 successively slightly shorter, 2d equal to

 in the closed wing. Entire upper parts, 

 including upper surfaces of wings and tail,

 mcmly about House Junction, Col., in May 

 and June (see Osprey, Sept. 1897, p. 7).
