Myiadestes unicolor Sclater 



Proc. Zool. Soc. London 24 : 299, Jan. 26, 1857. 

 ==Myadestes unicolor unicolor Sclater. See Hellmayr, Catalogue of birds 



of the Americas 7 : 443, 1934. 

 22377. Adult female. Cordoba, State of Veracruz, Mexico. Collected 



by Auguste Salle. Received from the Maison Verreaux, Paris. 

 Since Sclater referred to male and female specimens, we may be sure that 

 he had at least two cotypes. One of these was retained by him and is now 

 in the collection of the British Museum (Natural History). Although our 

 bird bears only the label of the Maison Verreaux, it is marked as "type de 

 Sclater," and there is no reason to doubt its cotypeship. 



Genus PLATYCICHLA Baird 



Platycichla brevipes Baird 



Review of American birds 1 : 32, 436, June and July 1864. 

 =Platycichla flavipes flavipes (Vieillot). See Hellmayr, Catalogue of 



birds of the Americas 7 : 425, 426, 1934. 

 23954. Immature (sex not indicated, but apparently female). "On the 

 coast of South America, probably in Brazil"==State of Rio de Janeiro, 

 Brazil. 1841 or 1842. Collected by G. R. B. Horner. Received from 

 the National Institute. 

 The U.S.S. "Delaware," on which Horner traveled, visited, in the course 

 of the 1841-1842 cruise, only two localities on the South American main- 

 land — Rio de Janeiro and Montevideo (see Horner, Medical topography of 

 Brazil and Uruguay, Philadelphia, 1845) . 



It should be noted that page 32 of the Review of American Birds, on 

 which Baird's new name appears, was published in June 1864, while page 33, 

 on which the major part of the description is found, was issued in July 1864. 



Genus ENTOMODESTES Stejneger 



Ptilogonys leucotis von Tschudi 



Archiv fiir Naturgeschichte 10 (1) : 270, 1844. 

 =Entomodestes leucotis (von Tschudi). See Friedmann and Deignan, 



Zoologica, New York 27: 52, 1942. 

 41908. Adult (sex not indicated). "Peru." Collected by Johann J. von 



Tschudi. Received from the Neuchatel Museum. 



Although Hellmayr (Catalogue of birds of the Americas 7:445, 1934) 



writes "type in Neuchatel Museum," it may be noted that von Berlepsch and 



Hellmayr (Journ. fiir Orn. 53: 6-20, 1905) failed to find such a specimen 



29 years earlier. Whether other cotypes than ours exist is not known to me.
