This species is a uniform ashy gray above and soiled white below; the bill is stout and decurved. These birds are as numerous in the Lower Rio Grande Valley as are the Sennett's Thrasher, frequenting thickets where they breed in scrubby bushes and cacti. Their nests are rather larger and more deeply cupped than are those of the last species and the eggs can easily be distinguished. They have a ground color of light bluish green, minutely dotted evenly all over the surface with reddish brown. Size 1.10 × .80. Data.--Brownsville, Texas, April 6, 1900. 5 eggs. Nest of sticks and thorns on a cactus in a thicket; 6 feet from the ground.

PALMER'S THRASHER. _Toxostoma curvirostre palmeri._ Range.--Very abundant in southern Arizona and southward into Mexico. The nesting habits and eggs of these birds are exactly like those of the last; they show a preference for placing their nests of sticks and thorny twigs upon cacti at elevations below five feet from the ground. Like the last, they generally raise two broods a season. 708. BENDIRE'S THRASHER. _Toxostoma bendirei._ Range.--Southern Arizona and Mexico; north locally to southern Colorado. This species is not as abundant in the deserts of southern Arizona as are the last species with which they associate. They nest at low elevations in mesquites or cacti, laying their first sets in March and early April and usually raising two broods a season; their three or four eggs are dull whitish, spotted and blotched with brownish drab and lilac gray. Size 1.00 × .72. Data.--Tucson, Arizona, April 15, 1896. Nest 3 feet up in a cholla cactus; made of large sticks lined with fine grasses. 709. SAN LUCAS THRASHER. _Toxostoma cinereum cinereum._ Range.--Southern Lower California. This species is similar to _curvirostre_ but the under parts are spotted with dusky. Their habits and nests are similar to those of the other Thrashers and the three or four eggs are pale greenish white, spotted with reddish brown. Size 1.08 × .75. Data.--Santa Anita, June 3, 1896. 3 eggs. Nest in a cactus. 709a. MEARNS'S THRASHER. _Toxostoma cinereum mearnsi._ Range.--Northern Lower California. This species is described as darker than the last and with larger, blacker spots on the breast and underparts. 710. CALIFORNIA THRASHER. _Toxostoma redivivum._ Range.--Southern half of California, west of the Sierra Nevadas.
