on hand have as well new feathers with buff markings as old, 

 i. e. worn feathers with whitish markings. The specimen from 

 Ang. has chiefly mottled feathers on the back and these are 

 freshly moulted; some of them have not even grown out to 

 their full size. The specimen from V^ has many mottled 

 feathers on its back, but these are comparatively much worn, 

 always more than the banded feathers, which also are present. 

 On the same specimen new feathers are also growing out, and 

 these are of the banded pattern. The specimen of the ^7^ 

 has only a few strongly worn mottled feathers left. The 

 majority of the feathers of this specimen displays the banded 

 pattern, but even these are not of the same age, some being 

 already more or less bleached with whitish markings and 

 worn, ragged edges, while others are quite fresh with buff- 

 coloured markings and entire edges. The specimen from 

 June as well has old feathers mixed in among the new. From 

 these facts it may be concluded that the moulting extends 

 över a comparatively long period, that it is partial, and that 

 at this locality the mottled feathers appear to belong to the 

 IDlumage of the months Aug. to No v. 



The latter period may be the paii^ing season, although 

 the same might be a little irregular as well. On the label of 

 the female from ^y^^ Consul Söderström has written, that 

 it had contained an egg, although this had been crushed by 

 the Indian, who had killed the bird. But the young chick 

 of this collection has been found ^y,^. The latter is partly 

 in down, especially on the chest, neck, crissum and rump. 

 The sides of the nape is also in down, coarsely mottled with 

 blackish and greyish white. The feathered parts of the lower 

 side is with regard to its colour rather similar to the same 

 parts of the adult bird, but the pinkish cinnamon ground- 

 colour is perhaps slightly paler. The upper back is black 

 with påle buffy edgings and subapical bands to the feathers. 

 The wing-coverts and the tertials are broadly margined with 

 a shade of pinkish cinnamon, which is a little paler than the 

 colour of the lower parts. In addition to these margins there 

 is also an inframarginal band of the same colour on each 

 feather. 



Chtjbb has used the name »latreillei » for the Attagis of 

 Chimborazo, thus identifying it with the bird, which Lesson 

 1831 described under the name Attagis latreillii from a col-
