T his species is apparently peculiar to the Bonin Islands, where Kittlitz discovered it in 1828. The
type specimen is in the St. Petersburg Museum, and a second is at Prankfort (Hartert, Kat. Vogels.
Mus. Senckenb. Ges. p. 6). The Leyden Museum possesses a third (the Myiothera passerina of
Bonaparte’s ‘ Conspectus ’), and a fourth is in the Vienna Museum.
The following description is taken from the specimen in the Leyden Museum:—
General colour of the upper parts olive-brown, shading into chestnut-brown on the rump, upper
tail-coverts, and ta il; the inside web of each feather much darker, approaching black on the back;
lores dark brown; eye-stripe very obscure; lesser wing-coverts brown, darkest on the inside web;
median coverts dark brown, with large olive-brown tip s; greater coverts nearly black, broadly tipped,
and narrowly margined towards the base, with olive-brown; primary-coverts black, with a broad

the basal half of the outer webs, and a spot where the emargination begins, olive-brown; tail-feathers
