subgenus called Taehytriorehis, and the aearesi ally of the present 

 species among the specimens of the British Museum appear-, ns ha> 



been pointed on( to me by Mr. (i. R. Gray, to be bis Buteo albono- 

 tatus (Cat. Accipitres [1848], p. 36). This latter bird does not 

 appear to me to differ from Cabanis's Buteo abbreviates, described 

 in Schombnrgk's ' Heiscn in Britisch Guiana,' vol. iii. p. 7.'!!', and I 

 sboulil be inclined to consider the two names as svnonvtnou-.

 The name of this Owl was inserted in the list of specimens of Ac- 

 cipitres 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 collec- 

 tion. 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 i> white; 

 the head above brownish-black outvie, with the ba-es of the fea- 

 thers bright rufous. The whole upper surface is brownish-black 



varied with this rufoUS colouring, every leather being CT OOOC d with a 

 broad subtenninal band of rnfons, sometimes witli a second, and 

 these bands being occasionally incomplete in the middle across the 

 shaft. The primaries and Becundaries are marked externally with 



rather square-shaped rnfons 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 Burface. Below, 

 the colouring is creamy-white tinged with pale rufous, 'iie breast- 

 feathers, particularly on the sides, baring broad terminations "i 

 black-brown, the belly-feathers narrower termination! and also 



lateral margins ofths MOM Colour. The tar.-i are civamv -white with 



a yellowish tinge in both my specimens, mors nearly pore white in 



that in the British Museum. They are thickly feathered down to 



the fissure of the toes. The fbrm i> that of other South American 

 Si/ruin, the fourth and fifth win--teath.i- being equal and fon( 



only slightly exceeding the third. The ipechneo which 1 take for
