in Laving the nuder tail-coverts as well as the middlp of the belly ])nio white, 

 and the whole rump pre}- like the ui)i)er tail-coverts ; but diil'er sliylitly bv the 

 darker grey of the flanks and rump, as also by the decidedly wider black area of 

 the mantle, the white nuchal band being consequently rather narrower. These 

 differences are not very strongly pronounced, and may prove to be independent 

 of locality. At all events, a series from Santarem should be e.xamined before 

 attempting any subdivision. 



E.Kamples from the north bank of the Amazon (Monte Alcgre, Manaos), and 

 from Barcellos, on the Rio Negro, belong, however, to typical C. m. manacus (L), 

 and are exactly like others from Surinam and Cayenne. The under tail-coverts are 

 grey ; the flanks darker and more extensively grey ; the middle of the abdomen 

 mixed with pale cinereous (instead of being pure white); tlie black colour of the 

 mantle mnch more e.xtended, the grey being nearly restricted to the npper tail- 

 coverts. 



The range of C. m. pitrus, according to our present knowledge, is as follows : 

 N.E. Brazil, Maranhfio: Miritiba (Schwanda coll.; Munich Museum); Para: city 

 of Para (Suethlage, Wallace, Layard), Marca da Legua (Steere), Maguary, Maraj6 

 (Steere), San Antonio do Praia (Hofl'manns), Onrem, on the Rio Guamd (Schnlz 

 coll. ; Mus. H. V. B.) ; Amazonia : Santarem, south bank of the Amazon (Riker); 

 Rio Madeira : Borba (Natterer), (Jaiama, Jamarysinho, S. Isabel, Rio Preto 

 (Hoffmanns), Engenho do Gama and S. Vicente, on the Rio Gnapore (Natterer). 



N.B. — Peruvian specimens, wliicli I have not seen, may also be referable to the 

 present form.

Two of the females are fully adult birds. Top of tlic head, nape, anterior and 

 middle portions of the back uniform cinnamon-rufous ; sides of the head, throat, 

 and foreueck rather paler ; the rest of the under i)arts still lighter, deep ochraceous. 

 The male differs by its generally lighter coloration, especially by its mnch paler, 

 bright creamy breast and abdomen. 



The immature female has the crown mixed with brownish grey, and the mantle 

 considerably duller, cinnamon-brown, corresponding to Des Murs' S. major, while 

 the rnfous-headed specimens agree with the typos of //. rnfum of Pelzeln.
