Compared with the series in the collection of the British 
Museum, I find these examples to differ from the true 
M. albicollis Yieill. in being olive-brown above instead of 
rufous brown, while the grey band across the throat is 
paler and narrower, and the white on the middle of the 
abdomen more extended, imparting a whiter appearance. 
Bill blackish above, yellow below ; tarsi and feet hazel- 
brown ; iris browii. Total length 9*9 inches, culmen 0*9, 
wing 4*3, tail 34, tarsus 1*2. 
I propose to'separate this race under the name of M. albi¬ 
collis paraguayensis. 
[This bird is resident and not uncommon with us. 
The large forests and the densely wooded hills of the 
locality afford a perfect home for it. I have nothing to 
add respecting the habits of these well-known birds. The 
habits of the four Thrushes which occur with us are so 
much alike that it is scarcely worth while to separate 
them in the description—even the nest and eggs cannot be 
identified, unless the parent bird is shot on the nest.—
