Lincoln's Sparrow seems to be a fairly common migrant or winter visitant in Coahuila; _M. l. lincolnii_ is the common subspecies. Burleigh and Lowery (1942:212) found this sparrow only in a grain field situated between a small pond and a narrow stream on the outskirts of Saltillo; the four specimens collected were identified as _M. l. lincolnii_. No. 31595 was obtained in a pine-oak association. _Melospiza lincolnii alticola_ (Miller and McCabe).--Miller, Friedmann, Griscom, and Moore (1957:398) listed _M. l. alticola_, which seems to be uncommon in Coahuila, from Sabinas on March 14. _Melospiza lincolnii gracilis_ (Kittlitz).--Miller (1955a:177) took an unsexed representative of _M. l. gracilis_ on April 7 in Carboneras Canyon of the Sierra del Carmen at 6700 feet. This occurrence is at the extreme eastern range of this subspecies. _Melospiza georgiana ericrypta_ Oberholser.--In Coahuila this subspecies of the Swamp Sparrow has been recorded as a migrant or winter visitant. Miller, Friedmann, Griscom, and Moore (1957:399) recorded it from Sabinas on February 22 to March 8 and from 8 mi. S Cuatro Cienegas on November 4. LITERATURE CITED ALDRICH, J. W., and DUVALL, A.
