A single S ad. from Prata, 14. xi. 05. No. 119. " Iris brown." 

 This specimen agrees in all essential characters with the type from Eastern 

 Pern, but is mnch paler grey both above auil below. The e.xamples collected by 

 Natterer on the Rio Madeira show the same pale coloration, and seem to indicate 

 that the Brazilian birds represent a different form. A good series of &esh skins 

 from Pern, however, should be compared before attempting any separation.

When describing this interesting addition to the fauna of Pard, I had only a 

 single female before me. Miss Snethlage has since published a note pointing out 

 that the male closely resembled that of H. poecilinota. This is quite an unexpected 

 discovery, as the type showed no trace of the black and fulvous markings on the 

 back and wings so conspicuous in the female of 11. poecilinota. 



Mr. Hoffmanns has now sent a good series of both sexes, which enables me 

 to speak more confidently about the characters of H. vidua. 



As stated by Miss Snethlage, the males resemble in general coloration those 

 of JI. poecilinota poecilinota. and //. p. lepidonota, having the back, the uj)per 

 wing-coverts, and inner secondaries marked with black and white cross-bars, but 

 differ at a glance by their whitish throat, which is in decided contrast witli the 

 cinereons colour of the remaining underparts. while in the two allied forms the throat 

 is quite as dark grey as the belly. The markings of the tail are the same ; each 

 •rectrix with a white apical margin and a roundish white spot on the inner web, 

 tlie outermost pair with a longitudinal white spot also about the middle of the outer 

 web. Sometimes there are two white spots on the inner web of the two or tliree 

 outer tail-feathers, but the same variation is to be observed in sjiecimens of the 

 allied forms. 



The females agree perfectly with the tyjjical example ; some of them have a
