Resembling the preceding, but larger ; tarsus longer, and more fully feathered in front to the toes. Varieties of plumage the 

 same, but that first described most usually mot with and more common than in the preceding. 



Mutt. — Upper parts light ashy brown, with large spots of dull white enclosed in edgings of brownish black. Throat white ; a 

 transverse band of brownish black and reddish white feathers across tho neck in front, succeeded by a largo patch of white. 

 Brca.st light brown, with large spots of white like the upper parts ; abdomen yellowish white, with hastate or crescent-shaped 

 spots of reddish brown disposed to form transverse bands ; under tail coverts, tibite, and tarsus, and under wing coverts 

 yellowish white ; quills and tail light brown, with spots of reddish white, edged (the spots) with brownish black ; tail wi'.h 

 about six transverse bands or pairs of spots of reddish white, enclosed or edged with dark brown. This is the plumage repre- 

 sented in Audubon's plate above cited, and is more commonly met with than tlie same plumage in the preceding species. It is 

 very probably the mature plumage. Another plumage is : Adult.' Like that just described, but much lighter, and tinged with 

 dull yellow, or ochre, having a faded or bleached appearance.' This plumage is not so frequent as in tho preceding species. 

 Another plumage is : Younger? Upper parts light greyish brown, with white spots very irregular in shape and confused, and 

 frequently predominating on the head. Abdomen nearly imspotted, yellowish white, or with traces only of spots or bands. 



Total length, female, about l(l| inches ; wing, 7 to 7j inches ; tail, 3j to 4 inches. Male rather smaller.

This owl may be immediately (listinf^iUHlied from the preceding by the more full featliering 

 of the tar.sns, generally einitimied withmit interrujitioii to tlie toes. Tiie tarHUs is al.so longer,
