The decidedly olive tint of the back, the deeper grey of the throat and breast, and 
the brighter yellow of the under surface render this species readily distinguishable 
both from WM. cinerascens and M. magister, though in the distribution of the rufous 
colour on the inner web of the lateral tail-feathers all these birds resemble one another. 
M. crinitus is a familiar species in the Eastern States, where it is a summer visitor 
during the breeding-season, and its habits are fully described by writers on North- 
American birds. Its nest is placed in a hole in a tree and the eggs “ curiously marked 
with fine ‘pen-lines’ and intricate pencillings of black and various shades of rich 
purplish brown over a buffy or creamy brown” 7°. 
2. Myiarchus inquietus, sp. n. — 
M. crinito similis, sed multo minor, abdomine pallidiore flavo distinguendus. Long. tota 7-0, ala 3-4, caudee 3°3, 
rostri a rictu 0°9, tarsi 0°8. (Descr. femine ex Acaguisotla, Mexico. Mus. nostr.) 
Hab. Mexico, Acaguisotla, Chilpancingo, Tierra Colorada, Rio Papagaio and Acapulco 
in the State of Guerrero (Mrs. H. H. Smith). 
In the large collection of birds recently received from Mr. and Mrs. Herbert H. 
Smith from the State of Guerrero are several specimens of a Myiarchus which we are 
unable to associate with any known species. At first we thought they might belong to 
the long disputed I. mexicanus, but the shorter wings and brighter yellow abdomen 
show that this is not the case. The species is evidently a small resident form of the 
migratory VV. crinitus of Eastern America, which, being isolated in the Sierra Madre del 
Sur, has acquired distinctive characters.
