Enl. 441, 437; Frisch, Ixxxxiv, Ixxxxv, Ixxxxvi; Naum. 46 and 

 47, 1 . Somewhat larger than the Common Owl; covered with lon- 

 gitudinal brown spots, transversely denticulated on the sides; 

 white spots on the scapulars, and towards the anterior edge of 

 the wing. The ground of the plumage in the male is greyish, 

 in the female reddish, from which circumstance they were con- 

 sidered for a long time as two species. (1) They build in the 

 woods, frequently lay their eggs in other birds' nests, and keep 

 themselves in the hollows of old trees. (2) 

 We reserve the name of 



Bubo, Cuv. 



Or Dues, for those species, which, with as small a conch as that 

 of the Syrnii, and the disk of feathers less strongly marked, are fur- 

 nished with tufts. Those which are known have large feet feathered 

 to the nails; such is 



Str. bubo; The Grand Due of naturalists; Enl. 434; Frisch, 

 Ixxxxiii; Naum. 44. The largest of the nocturnal birds; fawn 

 coloured, with a brown streak, and lateral points on each fea- 

 ther; the brown predominates above; fawn coloured underneath; 

 tufts almost entirely black.(3) 



The Tufted Chouetes, Vaill. Afr. xliii, 



Are mere Dues, whose tufts more widely separate, and placed 

 farther back, can scarcely be elevated above a horizontal line. They 

 are found in both hemispheres. (4) 



NocTUA, Savigny. 



Neither tufts, nor an open or deeply set conch; opening of the ear 

 oval, and hardly any larger than in other birds; the disk of fringed 



(1) The Str. sylvestris, rufa, nodua, alba of Scopoli, and the Str. solonienm, which 

 Gmelin has intercalated in his system, are too undetermined to be considered other 

 than varieties, and probably of the stridula. It is well to know that in the whole 

 of this genus the females are redder than the males by not attending to this, the 

 species have been improperly multiplied. 



(2) Add the Str. pagodarum. Tern. Col. 220, 



(3) We cannot admit the Str. scandiaca, L. whose only foundation is a figure of 

 Rudbeck, probably taken from a variety of the Grand Due. Add Str. magellanica, 

 Enl. 585, from which the Str. virginiana, Daud. II, 13, and Wils. Am. VI, 1, 1, or 

 Str. pinicola, Vieill. Am. 19, only differs in being of a more reddish tint. Str. 

 ladea, T. Col. 4. 



(4) Str. griseata, Sh.; Vaill. Afr. 43, of Guiana. Str . strepitans, T.Col. 174, and 

 of Batavia, 229. 



Add Str. dnerea, Gm., Bonap. Am. Orn. pi. xxiii, f. 2. Am. Ed.
