REVIEW OF AMERICAN BIRDS. 



[part I. 



Turdus wilsonii, Bon. Obs. Wils. 1825, No. 73. 



Turdus minor, D'Okb. La Sagra's Cuba Ois. 1840, 47, pi. v (Cuba). 



Hah. Eastern North America ; Cuba; Panama (winter). 



There is not much variation in the color, and but little in the size 

 of this species. The spots on the breast are sometimes more distinct 

 than common, but less so than in T. ustulatus, aud they never extend 

 so far back. 



It is a matter of some geographical interest that Mr. Drexler 

 obtained the true T. fuscescens at Fort Bridger, in the Rocky 

 Mountains, instead of T. ustulatus, its western representative. 



The collections of the Smithsonian Institution do not contain 

 specimens of this species from any point north of Fort Garry, nor 

 south of the limits of the United States, although Mr. Lawrence has 

 a skin from the Isthmus of Panama. I do not find it quoted as from 

 beyond the United States by recent authors.

Turdus ustulatus.

 Rep. XII, II, 1860, 171. 



Additional specimens of this bird, received since the publication 

 of the " Birds of North America," have satisfied me of the validity 

 of this species. Of the diagnostic characters there enumerated, I 

 find that of the fulvous or yellowish brown of the axillars (and to 

 some extent of the tibiae), as compared with their purer ash in fus- 

 cescens to be a constant one. The spots on the breast are much 

 better defined, darker, and extend farther back on the breast. The 

 Bides are more of a yellowish-brown. The bill is much darker, 

 being dark browni except at the base of the lower mandible, which is 

 yellowish, and in marked contrast to the remainder; while in fusees-
