Tbe males agree in every way with those from Teffe and Humaytha. All have 

 the under wing-coverts and the qiiill-lining broadly white ; in none is there any 

 white at the base of the interscapular feathers. The female differs slightly from 

 Venezuelan specimens of T. c. glaucus by having the throat rather browner and 

 mi.xed with deep baff, and the under mandible brown instead of whitish. Breast 

 and abdomen, too, are a shade deeper ferruginous. Like T. c. glaucus, it has a 

 large concealed white dorsal patch. 



I have examined the specimens from Salto do Girao (Mus. Vindob.) and Rio 

 Jiirua (Mus. Paulista) — in both cases males only were obtained — and found them 

 to belong to persimilis. Miss Snethlage informs me (in litt.) that the bird recorded 

 s.n. T. c. hojfmanniii {tide supra) likewise turns out to be peisiinilis. 



The range of T. c. persimilis is therefore as follows : 



North Brazil : Teffe, Rio Solimoes (Hoffmanns); Rio Madeira: Salto do Girao 

 (Natterer), Hnmaytha, Calama, Maruins, Rio Machados (Hoffmanns); Rio Jurua 

 (Garbe); R. Tapajoz, left bank : Itaituba (Hoffmanns), Villa Braga (Snethlage) ; 

 right bank : Bella Vista (Snethlage) ; Arumatheua, left hank of the R. Tocantins 

 (Snethlage).*

Nos. 96, 248, 328. SS ad., S vix ad., Calama, 23. vi., 22. vii., 2. viii. 1907.— 

 Wing 73, 70; tail 48, 49; bill 16— 17^ mm. "Iris dirty white, feet light 

 plumbeons, bill black, below greyish blue." 



Nos. 97, 345, 362, 368. ? ?, Calama, 23. vi., 7, 10, 11. viii. 1907.— Wing 

 67—69; tail 45—47 ; bill 16J— 17J mm. "Iris dirty white, feet light plumbeous, 

 bill black, below grey." 



The specimens differ from topotypical Peruvian examples by their rather 

 shorter, broader bill. The males have, too, the under wing-coverts uniform dark 

 grey, not mixed with white, and the females are decidedly paler rufescent brown 

 on the back. These trifling differences are, however, not likely to be constant. 



P. mnrgaritata is for the first time recorded from the Madeira district. 

 Previously it was only known from Eastern Peru, where Bartlett and Hauxwell 

 had obtained specimens at Xeberos and Chamicuros, and from Marabitanas, on the 

 upper Rio Negro, whence Natterer sent a series to the Vienna Museum.
