No. 275. ? ail, Calama, 20. vii. 1907.— Wing 03; tail (incomplete); bill 

 12 mm. 



" Iris brown, feet dark grey, bill black." 



The adult male (No. 0), like the type and several examples from Teffe, 

 has the j)ileam and mantle deep cinnamon-rnfons, with scarcely any brownish 

 sufifasion. The two other specimens and an adult female from Bella Vista (right 

 bank of the Tapajoz) are somewhat intermediate between .S^. ;•. amazonica and 

 S. r. rutilans: They have the vertex and mantle brown like the latter, bnt the 

 lateral interseapnlar feathers are entirely or partly ferruginous, and there is a 

 decided rnfous admixture across the nape. 



The range of S. r . amtzonka is, accordingly, as follows : ITorth-Easteru Peru: 

 Xeberos, Chamicnros, Chyavetas (Bartlett), Yurimaguas (Stolzmanu). North 

 Brazil: Tette, Rio Solimoiins (Hoflfmanns) ; Calama, llio Madeira (Hoffmanns); 

 Itaituba, left bank (Hoffmanns), Bella Vista, right bank of the Rio Tapajoz 

 (Snethlage) ; Santarem (Riker). 



S. r. rutilans Temm. inhabits the Rio Negro and Orinoco district (cf. Noi;. Zool. 

 xiv. p. 13), but occurs also in Lo.ver Amazonia on the banks of the Tocantins. I 

 have examined a specimen from C'ameta in the Berlin Museum,* and an adult female 

 obtained by Miss Snethlage at Arumathena,t and found them jierfectly agreeing 

 with my large series from Venezuela, etc. 



Still farther to the east, near Para and on the Oapim and Guama rivers, 

 another distinct form, S. r. omissa Hart., is met with, while a fourth race, .S'. /■. trrtia 

 Hellm., dwells in Western Mattogrosso (Rio Guapore) and in the north-western 

 parts of Sao Paulo (Irisanga).

No. 220. ? juv., Calama, 14. vii. 1907.— Wing 03 ; tail 01 ; bill 12^ mm. 



The adult female agrees exactly with Pelzeln's type-specimens kindly lent by 

 Dr. von Lorenz, and others from Goyaz, Rio Grande (Northern S. Paulo), etc., in the 

 Tring and Berlepsch Museums. The principal character of (S. r. ctdpitm consists of 

 the pileum and upper back being uniform fox-red, in decided contrast to the pale 

 olive-brown rump. Two females taken by Miss Snethlage on the island of Goyana, 

 Tapajoz,^ are in every respect similar to typical examples, while a single S ad. from 

 Arumathena (Tocantins §) is much paler, buffy brown, on the rump. 



In coloration the sexes are alike, but the females are decidedly smaller. The 

 Rio Madeira appears to form the western limit of the range of vulpina, since farther 

 to the west, on the Rio Pun'is, another form, S. culpimi alopecias (Pelz. |i) is 

 met with.
