the younger bird only differs in having the head varied like the back, 

 and being generally more rufous. 



The other American species of this genus of which I have seen 

 specimens are : — 



1. Syrnium hylophihim (Temm. PI. Col. 373), from Brazil. Mus. 

 Brit, et Acad. Philadelph. 



2. Syrnium rufipes (King, Zool. Journ. iii. 426), from Tierra del 

 Fuego. Mus. Brit. Perhaps the same as the Chilian species figured 

 by Des Murs as Ulula fasciata, Icon. Orn. pi. 37. 



3. Syrnium virgatum, Cass. (Journ. Ac. Phil. vol. ii.) (S. squa- 

 mulatum, Bp. — S. zonocercum, G. R. Gray), from S. Mexico and 

 Central America. 



4. Syrnium polygrammicum, G. R. Gray in Mus. Brit, ex Brasil. 

 An undescribed species very nearly allied to the last. 



5. Syrnium albigulare, Cass. (Journ. Ac. Phil. vol. ii. pi. 4. 

 p. 52). — S. macabrum, Bp. — S. albipunctatum, G. R.Gray in Mus. 

 Brit. From Bogota. 



4. Scops usta, sp. nov. 



Siqjra saturate castaneo-brunnea, plumis omnibus nigro subtilis- 

 sime vermiculatis : facie et gula pure castaneo-brunneis, hac 

 pallidiore : linea post regionem auricularem, cornuum capitis 

 extantium marginibus latis et pileo supero nigris : alarum

 ochracescenti-albidis, quinque aut sex fasciis latis in pogonio 

 externa, maculas quadratas efficientibus, nigris transvittatis ; 

 cauda ex eodem colore sed fasciis nigris pcene obsoletis : subtus

 busfiavis. 

 Long, tota 8*5, alee 7"0, caudae 4*0, tarsi 1*2. 

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

 This species is founded on the Scops which I mentioned as occur- 

 ring in Mr. Bates's collection from the Upper Amazon in these 'Pro- 

 ceedings' for last year (p. 201). It is distinguishable from every 

 other South American member of the genus, as far as I am ac- 

 quainted 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 collection from the Rio Napo to 

 this same species. It presents nearly the same appearance on its 

 lower surface, but the colouring above is more like that of Sco])s 

 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 examples with any of ten species which have been already 

 described as inhabiting different parts of America, as follows : —
