BIRDS OF SOUTHERN VERACRUZ — WETMORE 291 



EMPIDONAX MINIMUS (Baird and Band) : Least Flycatcher 



Tyrannula minima W. M. Baikd and S. F. Baikd, Proc. Acad. Nat. Sci. Philadelphia, 

 vol. 1, Sept. IS, 1843, p. 284 (Carlisle, Pa.). 



This is the most common of the flycatchers from the north, specimens 

 having been taken as follows : Near Tres Zapotes, March 17, 20, 23, 

 28, and 31, and April 3 and 11, 1939, and January 18 and 19, March 14, 

 and 27, and April 6 and 11, 1940; near Tlacotalpam, February 15. 

 Specimens in full molt were shot on March 28 and April 3 and 8. 

 These flycatchers were found usually in quiet spots out of the wind in 

 the shelter of thickets and at the edge of forest. All were silent, 



EMPIDONAX FLAVESCENS IMPERTURBATUS Wetmore 



Empidonax flavescens imperturbatus Wetmore, Auk, vol. 59, Apr. 1942, p. 267 

 (Volcau San Martin, Sierra de Tuxtla, Veracruz, Mexico). 



Carriker found this flycatcher fairly common in the smaller trees 

 and undergrowth in the virgin forest on Volcan San Martin, where 

 it ranged from 3,000 feet across the summit. It was quiet and rather 

 shy. Four specimens were taken on April 16, 17, and 18, including 

 two males and two females. This mountain marks the northern out- 

 post for the species which has not been known before north of Chiapas. 



EMPIDONAX ALBIGULARIS AXILLARIS Ridgway 



Empidonax axillaris Ridgway, in Baird, Brewer, and Ridgway, History of North 

 American birds, vol. 2, Jan. 1874, p. 363 (Orizaba, Veracruz). 



The only specimen is a male taken by Carriker near Tlacotalpam on 

 February 20, 1940. It was found at the border of a clump of thorn 

 trees in a pasture north of the town and was the only one seen. This 

 bird has the following measurements : Wing 62.0, tail 55, culmen from 

 base 13.4, tarsus 16 mm. It is marked by the buffy brown of the 

 under wing coverts, edge of the wing, and tibia, differing in this 

 respect from other species of the genus found here. 47 



MYIOBIUS SULPHUREIPYGIUS SULPHUREIPYGIUS (Sclater) 



Tyrannula sulphureipygia P. L. Sclater, Proc. Zool. Soc. London, 1856 (Jan. 26, 

 1857), p. 296 (Cordoba, Veracruz). 



Carriker found these interesting birds common on the lower slopes 

 of Cerro de Tuxtla below 1,200 feet, more abundantly below 800 feet. 

 They ranged in undergrowth and in the smaller forest trees, often in 

 company with the bands of little forest birds so common in the Ameri- 

 can tropics. He secured specimens on March 11 and 29, April 9, and 

 May 6 and 7. He did not record it on Volcan San Martin.
