 Hab. Ega, on the Upper Amazon (H. W. Bates). 



This species is founded on the Scops which I have mentioned as occurring in Mr. Bates' 

 collection from the Upper Amazon, in the ' Proceedings of the Zoological Society ' for 

 1857, p. 261. It is distinguishable from every other South American member of the 

 genus, as far as I am acquainted with them, by its rich brown colouring above and 

 below, and by the longitudinal lines below not being crossed as in Scops choliba and S. 

 atricapilla. I am inclined to refer the Scops which was contained in M. Verreaux's col- 

 lection from the Rio Napo to this species. It presents nearly the same appearance 

 on its lower surface ; but the colouring above is more like that of Scops choliba, and I 

 think it is probably a young bird. The birds of this genus are difficult to distinguish, 

 and I have been unable to identify the present example with any of ten species which 

 have been already described as inhabiting different parts of America, as follows : — 



1. Scops asio (Linn.), Cassin, Birds of Californ. p. 179. 



Hab. Whole of N. America ; chiefly Atlantic States. Mus. Brit. 



2. Scops maccalli, Cassin, Birds of Californ. p. 180. 

 Hab. Texas and N. Mexico. 



3. Scops flammeola, Kp. — Strix flammeola, Licht. in Mus. Berol. 

 Hab. Southern Mexico. 



4. Scops choliba, Vieill. — Strix crucigera et undulata, Spix. 



Hab. Cayenne, Brit. Guiana, Brazil, Eastern Peru, Bolivia, and New Granada. Mus. 

 Brit. 



5. Scops portoricensis, Less. : Des Murs, Icon. Orn. pi. 26. 

 Hab. Puerto Rico and New Granada. Mus. Paris.
