procta nigrocapillus Gray, and might possibly be a subspecies 

 of the same. It has the whole head and nape dark grey, some- 

 what similar to Ridgway's »deep Mouse gray» (1912). Un- 

 like in N. nigrocapillus this colour prevails on the sides of the 

 head as well, although the paler bases of the feathers may 

 shine through in the preserved specimen. This same grey 

 colour extends also somewhat on the foreneck, so that it forms 

 a collar below the dirty whitish throat. The upper mantle 

 finely vermiculated with dull rufous on a brownish-black 

 ground-colour. Towards the upper back the wavy black and 

 rufous bands become somewhat coarser and more pronounced, 

 at the same time as some widely scattered, very small white 

 spöts appear. This pattern extends also över the lower back 

 and the upper tail-coverts, but the white spöts are a little 

 larger there, although not numerous. Scapulars also similar. 

 The upper wing-coverts are brigther, vermiculated mth black 

 and dull rufous and with numerous buffish spöts accompanied 

 with black spöts, both of which have a tendency to form trans- 

 verse irregular bars on the greater coverts. The primaries are 

 dark brown with irregular, more or less wavy bars on the outer 

 web, and vermiculated with the same colours on the inner 

 web. The secondaries darker with less numerous buffy bars 

 on the outer web and with vermiculations between them, 

 but with the inner web uniformly blackish. Chest below the 

 dark grey collar, and breast cinnamon rufous with some wavy 

 dark bars on the concealed parts of the feathers. Remain- 

 ing under parts transversely barred with buff (paler on the 

 hindmost parts) and dark brown. Wing 170, tarsus about 

 57 mm.

This is evidently an alpine species which always lives at 

 a great altitude and also breeds there. A young specimen 

 collected on the northern side of Cotopaxi at an altitude of 

 11000 feet proves the latter fact. 



Consul Söderström has also presented four eggs of this 

 species measuring 52,3 X 37,3; 51,8 x 37,2; 52,6 X 37,8; 57,2 

 X 39 mm. They have been collected on Pichincha at an 

 altitude of 11500 f., ^y^ 1921.
