The three female.s obtained by Natterer at Borba, as well as another from 

 the Rio Icanna (upper Rio Negro), in the Vienna Museum, are, in every respect, 

 similar to examples from the Rio Napo, East Ecuador, in the Bfunich Museum. 

 The series ditfers from 3L m. morphoeus, of East Brazil (Rio de Janeiro to 

 Para), in smaller white chin-spot, lesser amount of white about the forehead, and 

 generally smaller size (wing 122 — 127, tail 110—122 mm).]

Dr. Lorenz having kindly forwarded to me the whole of Natterer's series, 

 I am enabled to state tliat the Amazonian specimens olitained by this celebrated 

 naturalist belong to the pale race described by Dr. Sclater from a single example 

 in the British Museum. An adult female from Borba, June 9, 1830, in the 

 Vienna Museum, agrees with the type in all essential particulars, except that 

 the bill is not (jiiite so long, and the back slightly more tinged with brownish.
