ORNITHOLOGICAL CLUB. 91 



6. Geothlypis velatus {Vieill.) = Trichas delafieldi, Aud., 1839, 

 Nutt., 1840, Heerniami, 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 irom 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. Dendroeca montana (TFils.). " 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 Rocky 

 Mountains in going from Alaska to the tropics. Yet it is not recorded 

 as from the Rocky Mountains or Mexico. 



10. DendrcBca caerulea (JrHs.) ^ azurea, Ste-ph. " Oregon," Towns- 

 end's List, 1839, Aud., 1839, Nutt., 1840. Recently found west of the 

 Rocky 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 (Xmih.). " California," Bonap., Notes Delat., 

 1853, but was perhaps from Nicaragua. Still, as it is common through- 

 out the Rocky 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 Dall. 



13 Hypocolius ampelinus, Bonap., 1850 (Consp.). "California." 

 This tpecies is now known to be from Sennaar, Upper Egypt, and is un- 

 doubtedly to lie removed from the list of West-coast birds. 



14. Lanius lahtora, Sijkes, = L. elegans, Swains., 1831, Nutt., 1840. 

 Supposed to have been received from Northwest America, but it inhalnts 

 Siberia. Stragglers may, however, cross Behring's Straits, like several 

 other birds. " L. elegans " of other American authors is Collurio ludovi- 

 cianus (L.) var. rohiistus, Baird, 1873. 



15. Vireo agilis, Licht., 1823, = V. virescens, Casl., not of Vieill., which 

 is V. bartrami. 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 River, as supposed by Swainson.
