BIRDS OF SOUTHERN VERACRUZ — WETMORE 315 



8, 1939, and January 19, February 28, and March 4, 1940; between 

 1,000 and 2,500 feet elevation on Cerro de Tuxtla, April 1, 1940. 



0P0R0RNIS PHILADELPHIA (Wilson) : Mourning Warbler 



Sylvia Philadelphia Wilson, American ornithology, vol. 2, 1810, p. 101, pi. 14, 

 fig. 6 (within a few miles of Philadelphia, Pa.). 



Carriker secured three of these birds, all males, near Tres Zapotes 

 on May 3, and on the lower slopes of Cerro de Tuxtla on May 7 and 

 10, 1940. Their winter home apparently is farther south, and be- 

 cause of the time of migration they have been missed in Mexico by 

 most collectors. Ridgway 65 knew of no valid records. Recently the 

 National Museum has received another male from A. E. Colburn 

 taken by P. W. Shufeldt in southern Veracruz, but without certain 

 data. The late dates for the Tres Zapotes specimens indicated 

 rapid northward migration for this species. 



GEOTHLYPIS TRICHAS TRICHAS (Linnaeus) : Maryland Yellowthroat 



Turdus trichas Linnaeus, Systema naturae, ed. 12, vol. 1, 1766, p. 293 (Maryland). 



Four specimens assigned to the typical race were secured at Tlaco- 

 talpam on February 6, 1940, and near Tres Zapotes on March 21, 

 1940, and April 11, 1939. These are lighter, less greenish above, and 

 lighter yellow below than the other races secured at this point. All 

 are males, with wing measurements of 51.4, 52, 54, and 54.5 mm. 



GEOTHLYPIS TRICHAS BRACHIDACTYLA (Swainson) : Northern Yellowthroat 



Trichas brachidactylus Swainson, Animals in menageries, 1838, p. 295 (north- 

 ern provinces of the United States). 



The four obtained were collected at Tres Zapotes on March 18, 



1939, and March 27, 1940, and Tlacotalpam on February 16 and 19, 



1940. These are distinguished from trichas by more greenish color 

 above and by more extensive yellow below. 



GEOTHLYPIS TRICHAS TYPHICOLA Burleigh: Athens Yellowthroat 



Geothlypis trichas typhicola Burleigh, Proc. Biol. Soc. Washington, vol. 47, 

 Feb. 9, 1934, p. 21 (Athens, Ga.). 



The four skins obtained were all secured at Tres Zapotes, January 

 18, 20, and 29 and March 5, 1940. These are decidedly deeper yellow 

 below, with darker flanks and darker dorsal surface than any of the 

 other yellowthroats secured. Their presence as winter migrants 

 here in southeastern Mexico is of interest in view of the present 

 known range of the subspecies in the southeastern United States. 

 Oberholser 66 has reported typhicola as casual in southern Louisiana 

 as a migrant and in winter.
