BIRDS FROM BRAZIL AND SOUTHERN VENEZUELA—FRIEDMANN 447 
Although no specimens of this piculet were obtained on the Rio 
Negro and the Casiquiare, the form does occur there. Pinto (Rev. 
Mus. Paulista, vol. 22, 1937, p. 365) records it from the Rio Negro and 
the Rio Branco. No specimens of P. buffoni exilis have been seen in 
the present connection and the trinomial nomenclature here used is 
based on Pinto’s treatment of these two forms. 
Another specimen from Puerto Ayacucho was preserved in alcohol. 
Recently Zimmer and Phelps (Am. Mus. Nov., No. 1312, 1946, 
p. 6) have recorded clarus for many localities in central and south- 
eastern Venezuela—Mount Auydn-tepui, La Unién, Suapure, 
Nericagua, and Upper Paragua River localities, among others.

The Cerro Yapacana birds, collected in April, were noted as having 
enlarged gonads. 
Though there is some variation in this excellent series, this appears 
to be wholly individual, and all are identified as certhia, although it 
may be noted that all average slightly grayer on the sides than do 
three skins from British Guiana. Hellmayr (Catalogue of the birds 
of the Americas, pt. 4, 1925, p. 262) reports a specimen from Mara- 
bitanas on the Rio Negro as D. c. juruanus Ihering. Skins in the 
present collection from the Brazilian localities listed above show some 
tendency to vary in the direction of juruanus but on the whole are 
nearer certhia.
