differently shaped bill; and it is, besides, much smaller, and dif- 
ferently colored. The relationships of the new species are really 
with the St. Lucas thrush, rather than with Palmer’ 8; for although 
the markings appear quite different, when we compare the sharp 
speckling of the under parts of cinereus with the faintly spotted 
breast of Bendirei, yet this difference might be produced by climatic 
influences, just as we have seen in the case of Lecontei. The size 
is the same ; and it is the difference in the shape of the bill, in the 
relative karis of the tarsus and toes, and in the wing-formula, 
rather than the coloration, that has caused my present decision, 
that H. Bendirei is not a desert race of H. cinereus. 
Bendire’s thrush is much rarer, in Arizona, than either the 
crissal or Palmers. It is resident in the southern portion of the 
Territory. It builds preferably on trees, sometimes thirty feet 
high, instead of on bushes. The egg is only -96 X *70; its color, 
grayish-white, with spots and larger blotches, principally about 
the greater end, of two shades of pale reddish-brown, with some 
lilac and lavender. 
single specimen is rather smaller (wing 3°75 etc.) and still paler, duller brownish above; 
2 this is owing to worn plumage, if not also, in part, to mummification with carbolic 
id).

are as distinctly and heavily spotted as in H. ru itself. The size is about as in 
Bendirei, and the coloration of the upper parts is much the same.
