SOME UNITED STATES BIRDS, NEW TO SCIENCE. 327 
habit our southwestern border ; they are much alike in color, differ- 
ing from our rich foxy-red thrasher very nearly as the homely gray 
pipilos of the same region differ from the smartly-dressed chewink 
— being pale dull brownish or grayish, with few or no definite 
markings, except in one instance. Let us pass them in review, 
so as to be better able to judge of a certain new species I am going 
to describe. I will first mention the St. Lucas Thrush (H. ciner- 
eus) ; it agrees with the thrasher, and differs from all the rest, in 
being thickly speckled with brownish-black over most of the under 
parts. It is dull brownish-gray above; the shape of the bill is 
shown in figure 70, beyond. We shall have to look at this spe- 
cies again, presently. Next, we have the Californian Mocking- 
Fig. 65. 
Brown Thrush (natural size). 
thrush (H. redivivus. Fig. 66). Its points are—the long arcuate 
bill; dark olive-brown color, paler below, gradually changing to 
Tusty-brown on the belly and to rusty-white on the throat ; heavily 
Streaked ear coverts, but no maxillary stripes nor spots on the 
breast ; length eleven inches or more, wing four or less, tail five 
or more, bill and tarsus, each, about 14 inches. This is the dark 
California coast form. In the arid Colorado river region, there is 
à variety of the same bird, identical in size, form and pattern of 
Coloration, but extremely pale-colored, as if really bleached with 
the heat and dryness of the desert. It is apparently very rare; 
I never saw but two specimens, one of which I was fortunate 
enough to shoot myself, and only know of two others, which Dr. 
Cooper secured when he was at Fort Mojave. This is Leconte’s
