120 DR. P. L. SCLATER ON THE GENUS coccyzus. [Mar. 8, 
fear, result in some confusion, unless steps are taken to explain how 
the matter stands, as I ‘now propose to do in the following list of all 
the species of the group, as far as I am acquainted with them. 
I may remark that there is one species, given in Cabanis and Heine’s 
account of the group, which I have not yet come across. This is 
Coccyzus cinereus, Vieillot, founded upon Azara’s “ Ceniciento”’ 
(Pax. ii. p. 368). There is stated to be an example of this bird in 
the Berlin collection obtained by Sello in Monte Video. 
The following diagnoses are for the more easy identification of 
the eight species which I have examined :— 
A. rostro inferiore ad basin flavo. 
major, alis EXtus rufis ........c000 ceeeeeeceee 1. americanus. 
a. venkre allio, minor, alis extus dorso concoloribus ...... 2. bairdi.

I now add the principal synonyms and geographical ranges of each 
species :—
