34. 1. Strix Americana, Aud. American Screech-Owl.--Barn Owl.

Plate CLXXI. Male and Female.

Feathers margining the operculum with the shaft and webs undeveloped.

Bill pale greyish-yellow; claws and scales brownish-yellow. General

colour of upper parts greyish-brown, with light yellowish-red

interspersed, produced by very minute mottling; each feather having

toward the end a central streak of deep brown, terminated by a small

oblong greyish-white spot; wings similarly coloured; secondary coverts

and outer edges of primary coverts with a large proportion of light

brownish-red; quills and tail transversely barred with brown; lower

parts pale brownish-red, fading anteriorly into white, each feather

having a small dark brown spot at the tip.

Closely allied to _Strix flammea_, but larger, and differing somewhat

in colour, being generally darker, with the ruff red. A character by

which they may always be distinguished is found in the operculum, the

feathers margining which are in the present species reduced to their

tubes, the shafts and filaments being wanting, whereas in the European

species each tube bears a very slender shaft, about half an inch long,

and furnished with about half a dozen filaments on each side.

_Male_, 17, 42. _Female_, 18, 46.

Southern States. Breeds from Texas to North Carolina. Never seen in
