Identical with specimens from Eastern Bolivia (Beni River). The males have 

 the under tail-coverts pare white, and in fully adult birds the interscapular region 

 when viewed from in front looks very dark, almost blackish. The form found on 

 the left bank of the Kio Tapajoz is likewise 'J'. Iinl:aiii. The females taken at 

 Itaituba by 3Ir. Holfmanns were erroneously determined as T. f. furcatoules, but 

 Miss Snethlage has lately obtained, in the same region, an adnlt male. T. sii/wni 

 Hellm., from Teffe, Kio Solimoens, while agreeing with 7'. balzani in the small 

 size, in the dark coloration of the interscapulium, etc., diflers at a glance by having 

 the nnder tail-coverts steel-black with white edges. Cf. Nov. Zool. xiv. 1007. 

 pp. 77-8. 



The range of T. balzani is as follows : — 



Eastern Bolivia: Salinas, Reyes (Maxwell Stuart; Tring Mu.seum). Central 

 Brazil, Amazonia: Calama, 8. Isabel, Borba, Allianca, Rio Madeira; Maruins, 

 Rio Machados (Hoffmanns) ; Itaituba (Hoffmanns), Campinho, Villa Braga (Sneth- 

 lage), left bank of Rio Tapajoz.
