228 DR. J. J. KAUP’S MONOGRAPH OF THE STRIGID&. 
liberality of Prof. D. Leiblein I was obligingly furnished with the original bird, from 
which Prof. Wagler took his description. I doubt whether it is an old bird. 
11. Scops asio, G. R. Gray’. 
Strix asio, Linn. 
nevia, Gmel. 
albifrons, Lath. : 
— lineatus et striatus, Vieill., Wils. 19. 1, 42. 1; Aud. t. 97. 
General plumage greyish or rusty red; toes with feathers. The wings 160, tail 76 
mm. long. 
Hab. N. America. 
12. Scops BRASILIENSIS, Bp. 
Strix brasiliana, Gmel. 
choliba, Vieill. 
—— crucigera et undulata, Spix. 
decussata, Licht. 
Scops portoricensis, Less. : des Murs, Iconogr. Pl. p. 26. 
The cape very dark brown, and rusty-red banded and spotted. Toes naked. 
Hab. Brazil. 
Prince Maximilian of Neuwied represents the female as reddish-brown, and the male 
grey-brown. The male shows more white on the belly and underside. 
The wings 155, tail 85 (according to the Prince 95 mm. long), head 47, tarsus 29, 
middle toe 24 mm. long. : 
I cannot find any true difference between this and the preceding species, because the 
feathers of the toes sometimes vary very much in members of the same species without 
giving the bird a distinctive character. We find this the case in the genera Bubo and 
Scops. 
13. Scops aTRICAPILLUS, Cuv. 
Strix atricapilla, Natt. Pl. Col. 145. 
With the crown of the head black, and pointed feather-horns. The back and cover- 
ing parts of the wings, throat, and upper part of the breast dark-coloured, like a 
Caprimulgus. Breast and belly similar to Otus vulgaris. Margin of the wings with from 
six to eight rusty-red, black, zigzag-spotted cross bands, which are clearer on the inner 
webs. Tail blackish rusty-red, spotted with eight ocellated cross bands of yellowish- 
white. 
Wings 177, tail 87 mm. long. 
Hab. Brazil. 
I cannot find any difference between this species and Scops lophotes, Less., from 
Cayenne. It has nearly the same dimensions: wings 179, tail 90, wing end 47 mm. 
' Nearly allied to this bird is the recently described Scops maccalli, Cassin, B. of California p. 108. (P.L.S.)
