A male sent in spirits from Boston by Dr Brewer :—The roof of 
the mouth is flat, with two longitudinal ridges, the sides ascending ; 
the posterior aperture of the nares oblong, 4 twelfths long, with an 
anterior fissure. The tongue is 7} twelfths long, deeply emarginate 
and papillate at the base, flattish above, with a faint median groove, 
the sides parallel, the tip narrowed and emarginate. The mouth is 
very wide, measuring 1 inch and 13 twelfth. ‘The cesophagus is 54 
inches long, of nearly uniform diameter throughout, as in all other Owls, 
its breadth being 1 inch. The proventricular glandules form a belt 
9 twelfths in diameter. The stomach is large, round, 1 inch 9 
twelfths long, 1 inch 7 twelfths broad, its walls thin, its muscular coat 
composed of rather coarse fasciculi, but without distinction into lateral 
muscles, the tendinous spaces circular, and about 8 twelfths in diame- 
ter ; its epithelium soft and rugous. The duodenum is 3 twelfths in 
diameter, and curves at the distance of 3 inches from the pylorus.
