.---A series of fan-tailed warblers col- lected by the junior writer in Salvador in 1925 .and 1926 differs in several respects from Euthlypis lachrymosa lachrymosa Cabanis of southern Mexico and from Euthlypis laehrymosa tephra Ridgway of northwestern Mexico. These southern Pacific coast birds are characterized as follows: Euthlypis laehrymosa schistaeea, subsp. nov. Southern Fan-tailed Warbler Type.--Male adult; no. 17,404, collection of Donald R. Dickey; Pine Peaks, Volcan Conchagua, Salvador; altitude 3,000 feet; February 27, 1926; collected by A. J. van Rossem; original no. 10,478.  Contribution from the California Institute of Technology. Subspecific 1/2haracters.--Similar to Euthlypis lachrymosa lachrymosa Cabanis, but dorsally clearer, purer slate color, particularly on rump and upper tail coverts; remiges and rectrices darker slate, sometimes slate-black; under parts with yellow of throat and abdomen more extensive and brighter (more lemon, less tawny) yellow, and in much more decided contrast o tawny of breast. Range.--Pacific coast of Central America from Chiapas (?) south to Salvador and probably to Ometepe, Nicaragua. Remarks.--Schistacea is the clear slaty extreme of the species, with contrasted under parts; lachrymosa occupies an intermediate position in characters as well as geographically; while tephra is the palest, most olivaceous race, with under parts least contrasted. The supposed slight differences in size between lachrymosa and tephra seem to be too intangible to have any diagnostic value in the series examined. The Guererro specimen is not typical of any race, but seems nearest to lachrymosa. Specimens examined.--Euthlypis lachrymosa lachrymosa: Mexico: Vera Cruz: Motzorango, 1; Orizaba, 1; Mirador, 1; Oaxaca: Pluma, 1; Guerrero: Acahuizotla, 1; Tamaulipas: Santa Leonor, 1. Euthlypis lachrymosa tephra: Sinaloa: Mazatlan, 1; Rio Mazatlan, 1; Chihuahua: Hacienda San Rafael, 7; Jalisco: Barranca Ibarra, 2. Euthlypis lchrymosa schistacea: Salvador: Volcan Conchagua, 4; Volcan San Miguel, 2; Colinas de Jucuaran, 5; Lake Olomega, 5; Volcan Sociedad, 4; Mt. Cacaguatique, 7; Guatemala: Barranco Hondo, 1; Mexico: Chiapas: Tuxtla, 2 (not typical).
