6. Geothlypis velatus (Vieill.) = Triclias delajieldi, And., 1839, 
Nutt., 1840, Heermann, 1858. “ Oregon and California.” It seems 
strange that a bird so common as G. trichas is in the East should be con- 
founded with such a different South American species. Townsend’s speci- 
men was doubtless from South America, but Heermann’s were only G. 
trichas. Lately recorded from Mazatlan, Mexico, and may therefore reach 
the Lower Colorado. 
7. Siurus auricapillus (Linn.). Oregon,” Nuttall, 1840, and recently 
recorded from Idaho, as well as Alaska and Mazatlan. “California,” 
Bonap., Notes Delat., 1853, but may have been obtained in Nicaragua. 
Still it very probably migrates occasionally through California. 
8. Dendrcsca montana (Wils.). “ California,” And., 1839 - 41, Nutt., 
1840. There is no further information respecting this very rare and 
scarcely known bird than is given by the above-named authors. 
9. Dendroeca striata (Forst.). “Oregon,” Aud. Syn., 1839. Not 
given by Townsend nor Nuttall, though it should pass west of the Eocky 
Mountains in going from Alaska to the tropics. Yet it is not recorded 
as from the Eocky Mountains or Mexico. 
10. Dendroeca caerulea Steph. “ Oregon,” Towns- 
end’s List, 1839, Aud., 1839, Nutt., 1840. Eecently found west of the 
Eocky Mountains, so that it may not have been confounded by Towns- 
end, etc., with Polioptila, as I ^suspected. It has not been detected near 
the coast. 
11. Setophaga ruticilla (Linn?). “California,” Bonap., Notes Delat., 
1853, but was perhaps from Nicaragua. Still, as it is common through- 
out the Eocky Mountains in summer, it may occur in California, though 
not known from Western Mexico. 
12. Collocalia ? unalaschkensis (Gmel.). According to Cassin (II- 
lust., 1855, 251), Gmelin’s bird belongs to the genus Collocalia, which is 
peculiar to the Pacific (tropical) islands, Japan, etc. If really found on the 
Aleutian Islands, some may be expected to straggle to our coast in winter, 
with other Asiatic species found there by Dali. 
13 Hypocolius ampelinus, Bonap., 1850 (Consp.). “California.” 
This tpecies is now known to be from Sennaar, Upper Egypt, and is un- 
doubtedly to be removed from the list of West-coast birds. 
14. Lanius lahtora, Sykes, — L. elegans, Swains., 1831, Nutt., 1840. 
Supposed to have been received from Northwest America, but it inhabits 
Siberia. Stragglers may, however, cross Behring’s Straits, like several 
other birds. “ L. elegans ” of other American authors is Collurio ludovi- 
cianus (L.) var. robustus, Baird, 1873. 
15. Vireo agilis, Licht., 1823, = V. virescens, Cass., not of Vieill., which 
is V. hartrami, Swains., 1831; not of Aud., 1839, nor Nuttall, 1840. 
This species, confounded by former authors with V. gilvus var. swainsoni, 
has not been found north of Mexico, nor perhaps in North America, unless 
Douglas really found it at the Columbia Eiver, as supposed by Swainson.
