MISCELLANEOUS NOTES AND OBSERVATIONS. 
Leucopternis OCCIDENTALIS. — Through the courtesy of 
Mr. W. F. Rosenberg the Norwich Museum has recently 
acquired a good skin of the rare Leucopternis occidentalism a 
species described by Mr. Osbert Salvin as long ago as 1876 
from an example obtained on Puna island on the Pacific coast, 
and which has long been one of our desiderata. 
Leucopternis is a well-marked genus of South American 
Buzzard-like Hawks, characterised by their plumbeous, or in 
some cases black and white, tone of plumage, and has been 
commented upon by my late father in “ The Ibis ” (“ Ibis,” 
1876, p. 470). 
Leucopternis is divisible into eleven species, all of which 
are now represented in the Norwich Museum, three of them, 
L. princeps, L. blumbea, and L. occidentalism having been 
added since the printing of the Catalogue in 1894. Our series 
therefore is now almost as complete as it is possible to make it. 
Mr. Rosenberg, who has had considerable experience of the 
avifauna of Western Ecuador and Western Columbia, S.A., 
informs me that the example of L. occidentalis which he has 
sent to the Museum, and which has all the appearance of being 
an adult, was collected at Quevedo, W- Ecuador. 
Mr. Rosenberg at the same time forwarded a young example 
of L. occidentalis, which appears to have been taken from the 
nest, and is ticketed Quevedo, February 27th, 1913. 
L. occidentalis is a smaller species than L. albicollis, from 
which it is primarily distinguished by its white tail terminating 
in a broad black bar. 
This is just the reverse of L. albicollis, which has a black 
tail with a terminal white bar.
