The name of this Owl was inserted in the List of Specimens of Accipitres in the 
Collection of the British Museum published in 1848 ; but no description of it has yet 
appeared. The type in the British Museum is immature, and nearly agrees with one in 
my own collection. Mr. Gurney’s specimen, from which my description is taken, 
appears to be nearly adult. All these three examples were received in collections from 
Bogota, and they are the only individuals of this species that I have yet met with. The 
face of this bird is white ; the head above brownish-black outside, with the bases of the 
feathers bright rufous. The whole upper surface is brownish-black varied with this 
rufous colouring, every feather being crossed with a broad subterminal band of rufous, 
sometimes with a second, and these bands being occasionally incomplete in the middle 
across the shaft. The primaries and secondaries are marked externally with rather 
square-shaped rufous spots, four or five in number. The tail has five cross-bands 
besides the terminal one formed in the same way, which bands appear whitish on the 
lower surface. Below, the colouring is creamy-white tinged with pale rufous, the 
breast-feathers, particularly on the sides, having broad terminations of black-brown, the 
belly-feathers narrower terminations and also lateral margins of the same colour. The 
tarsi are creamy-white with a yellowish tinge in both my specimens, more nearly pure 
white in that in the British Museum ; they are thickly feathered down to the fissure of 
the toes. The form is that of other South American Syrnia, the fourth and fifth wing- 
feathers being equal and longest, only slightly exceeding the third. The specimen 
which I take for 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 hylophilum (Temm. Pl. Col. 373), from Brazil. Mus. Brit. et Acad. 
Philadelph. 
2. Syrnium rufipes (King, Zool. Journ. ili. 426), from Tierra del Fuego. Mus. Brit. 
Perhaps the same as the Chilian species figured by Des Murs as Ulula fasciata, Icon. 
Orn. pl. 37. 
3. Syrnium virgatum, Cass. (Journ. Ac. Phil. vol. ii.) (S. squamulatum, Bp. ; S. zono- 
cercum, 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.
