* ASTUE, sp. 



Mr. Wallace's collection has a young bird from Lombock, which I cannot 

 identify. From its rufous coloration it seems to belong to the A. trinotatus 

 group. 



Young. Above rufous, the feathers creamy white at their bases, barred and 

 centred with ashy brown ; nape slightly streaked with creamy buff; sides of 

 face and neck entirely rufous, streaked with ashy brown, with faint indications 

 of a buff eyebrow ; wing-coverts ashy brown, witli broad rufous margins ; quills 

 ashy brown, narrowly margined and tipped with rufous, barred with darker 

 brown, more plainly seen on the under surface, which is pale rufous at base of 

 inner web, ashy grey towards the tips ; tail ashy brown, tipped with pale brown, 

 washed externally with rufous, crossed with ten narrow bars of darker brown 

 more distinct on the under surface, the feathers being pale rufous at base of 

 inner web ; under surface of body creamy buff; the throat with a broad central 

 line of greyish brown, the entire breast streaked with longitudinal markings of 

 brown, the under tail-coverts whitish with rufous-brown spots ; thighs pale 

 fawn-colour, spotted and barred with clear rufous ; under wing-coverts huffy 

 fawn-colour, streaked with rufous brovra ; cere pale yellow ; bill black ; feet 

 pale yellow; iris olive. Total length 16 inches, culmen 1, wing 8-9, tail 7-3. 

 tarsus 1-35. 



This may be the young of Astur wallacii ; but the bird from Bouru is wliat I 

 consider to be really the young of that species.
