gratory than either the vultures or falcons, are even more 

 widely diffused. Two thirds of the North American specie& 

 are found in Europe, and Jiammea, otus, and brachyotus, all 

 belonging to the typical genus, are spread over the whole 

 world. As in the case of the falconidce, the species entering 

 the subtypical generic group are mostly confined to particular 

 countries, while the aberrant genus nyctipetes, like cymindisy 

 is mostly South American, one species only {ciinicularia) ex- 

 tending from the 40th degree of south latitude by the valley of 

 the Mississippi, to an equal degree north of the equator. Though 

 the American ornithologists have all considered their strix otus 

 to be actually the same with the European species, Cuvier says 

 that the one figured by Wilson, 51, fig. 3, (and 19, fig. 1, 

 young), is different, while he considers the mexicana {clamator, 

 Vieill., lo7igirostris, Spix,) to be merely a dark variety of th# 

 European bird*. Strix cinerea of Latham, Bonaparte, and th' 

 Fauna Boreali- Americana is identified by Temminck with hi 

 lapponica.

* Though many foreign owls, and, among others, four Australian ones, 

 castanops, pcrsonata, cyclops, and delicatuliis, of Gould, were formerly con- 

 founded yi\\\\ flammea, causing it to be considered as quite a cosmopolite, its 

 range is actually very extensive, there being no difference, according to Tem- 

 minck, in the species as existing throughout Europe and Asia, the whole of 

 northern and tropical Africa, and iu Japan. The North American barn-owls, 

 he says, differ only in a few darker tints of the plumage; but the South 

 American ones are distinct.
