Nos. G07, 882. ? ? ad.. 22. v., 22. vi. 06. " Iris greyish brown, feet grey, bill

This is one of the most interesting Bpeciea in the collection. Hitherto only 

 two specimens were known, an adult S (the type) in Count Bcrlepsch's Museum, 

 obtained by G. Garlepp in Northern Bolivia, and an immature <$ from the Bio 

 durua, sent by Garbe to the Mnsen Paulista. 



The adult c? collected by Mr. Hoffmanns agrees with the type except that the 

 white bands on the rectrices are confined to the inner webs. The second male has 

 the general colour of No. 689, but there are still some brown feathers of the juvenile 

 plumage to be seen. This specimen is particularly interesting, as it seems to 

 indicate that the young bird, before attaining the coloration of the adult (?, moults 

 into a transitional plumage, since the newly-grown greater upper wing-coverts and 

 inner secondaries show a narrow white apical margin and a distinct black sub- 

 terminal band, while they are uniform schistaceous in the adult o<J. 



The ? of this species, which has not yet been described, is coloured as follows : 

 Nasal feathers cinnamon rufous with black tips; lores, sides of the head (including 

 a broad superciliary stripe), throat aud foreueck deep cinnamon rufous (Ridgw. iv. 

 fig. 16), passing into reddish cinnamon on the middle of the breast ; rest of uuder- 

 surface pale olive-brown, under tail-coverts slightly washed with cinnamon. 

 Forehead aud crown mainly black, the feathers of the former ferruginous at the 

 base, those of the latter narrowly edged with dull rufescent brown ; occiput dull 

 cinnamon rufous, clouded with dusky. Back pale olive-brown, each feather with 

 a broad (about H to 2 mm.) black snbterminal bar and a rather narrower cinuamon- 

 rufons apical band. These markings are more sparingly distributed aud less 

 pronounced on the rump. The feathers of the upper back are pale cinnamon- 

 rufous on the basal half, as in the female of G. leucaspis (Scl.). Upper tail-coverts 

 clear cinnamon rufous, each feather with a distinct Muck snbterminal bar. Lesser 

 aud median upper wing-coverts olive blackish, broadly edged with deep cinnamon 

 rufous ; greater series dark olive-browu or blackish, with a broad cinnamon-rufous 

 margin on the tip aud along the outer web. Quills dark brown, outwardly 

 rufescent brown, the secondaries with a broad, pale cinnamon apical band, followed 

 by a narrow blackish line. Tail-feathers clear cinnamon rufous, crossed by six 

 to seven black bands. Bend of the wing cinnamon rufous. Axillaries and under 

 wing-coverts pale olive-brown. Bill black, lower mandible whitish. 



Count Berlepsch (I.e.) snggested that Pithys lunulata Scl. & Salv.* might be 

 the ? of G. sahini. After comparing our specimens with the type in the British 

 Museum, I am led to believe that such is uot the case. The bird from the Ueayali 

 agrees with the <? ad. of G. sahini in the colour of the throat and sides of the head, 

 but the upper parts are olive-brown, as in the ? of this species, aud marked in the 

 same manucr. The light bands on the back and the margins of the wing-coverts 

 are, however, buff (not cinnamon-rufous), the rectrices dark brown with three to four 

 white cress-bands on the inner web, and there is a very small whitish inter- 

 scapular patch. It must also be remembered that Taczanowski described a similar 

 specimen (marked ?) obtained by Stolzmann near Yurimaguas, North Peru,t and 

 it is, therefore, probable that G. sahini and G. lunulata are nearly allied, but 

 distinct species.
