2 ? ? ad. from Goyaz. — Wing 53; tail 43, 44 mm. 



One adnlt from Chiqnito.s, East, Bolivia. — Wing 54J ; tail 45 mm. 



N.B. — The specimen from Cliiquitos is practically identical with the Brazilian, 

 ones. 



I have not seen the examples from Rio de Janeiro, and Paracati'i, northern 

 Minas Geraes, recorded hy Reinhanlt.* The former may belong to 0. o. obsoktiim, 

 while the latter are most certainly referable to 0. o. cinerasceiis.

Elainea cristata Pelzeln, Zur Ornilh. Bras. ii. p. 177 (1SG8. — Goiaz) ; Berlopicli & Leverkiihn, 

 Ontis vi. 1890. p. 12 (Lavrinhas). 



Nos. 1854, 1856. Adnlts (not sexed), Goyaz, March 1000.— AVing 08, 69 ; 

 tail 04 ; bill 11 mm. 



No. 1700. (J in moult, Faz. Esperanca, January 1900. — Wing 74 ; tail 06i mm. 



Althongh synonymised with E. albiceps by Dr. Sclater.f this species is a very 

 distinct one, being easily recognisable among its congeners by its full, dense, 

 brownish crest without any white at the base, and by its rather short, rounded 

 wings. In general coloration it most resembles E. payana. Of. also Beidepsch, 

 Omis xiv. 1907, pp. 398-9. 



Besides the above specimens I have examined Natterer's typical series in the 

 Vienna Museum, an adnlt female from Lavrinhas (obtained by Prof. Behn and 

 actually in the Berlin Museum), and some thirty Bahia skins in Count Berlepsch's 

 collection. 



69. Elaenia gaimardii gaimardii (D'Orb.). 



Muacicdjiiird Gaimurdii D'Orbigny, Voyat/e, Oiseaux, p. 32(i (between 1838 and 1847. — Yuracar^s, 

 Eastern Bolivia). 



No. 1671. Adnlt, Faz. Esperanga, December 1905. — Wing 59 ; tail moulting; 

 bill 10 mm. 



No. 2176. Adult, Rio Thesouras, May 1906.— Wing 57 ; tail moulting ; bill 

 11 mm. 



I am unable to detect any differences between D'Orbigny's type and Brazilian 

 specimens (including the types of E, cleyans Pelz. from Mattogrosso, Borba, and 

 the Rio Negro). 



70. Elaenia caniceps (Sws.). 



Tyramiiila caniceps Swainson, Birds Brazil tab. 4'.l (1841. — Brazil). 

 Elainea taczanowsl-ii Berlepsch, Ibis 1883. p. 137 (Bahia). 



SerpnplHiija ulhngrisca (neo Sclater & Salvin) Allen, Bull. Amer. Miis, iii. 1892. p. 333 (Abrilongo, 

 Chapada : Mattogrosso). 



No. 1920. 6 ad., Goyaz, March 1000.— Wing 61 ; tail 56 ; bill lo mm. 



This bird agrees exactly with the type of E. taczanowskii, and the two skins 

 from Mattogrosso, named S. albogrisea by Dr. Allen. I am greatly indebted to 

 this gentleman and to Count Berlepsch for the loan of these valuable specimens. 



Two species have hitherto been distinguished by Count Berlepsch, Dr. Sclater, 

 and others : (1) E. caniceps, with the back more or less olive-green, the crown 

 patch and the wing markings pale yellow, and the flanks and under tail-coverts
