BIRDS OF SOUTHERN VERACRUZ — WETMORE 281 



on April 11, and two at 1,500 feet elevation on Cerro de Tuxtla, May 

 5 and 9. 



Griscom 35 considers that the birds from southeastern Mexico are 

 to be united with those of Guatemala under the one name guatimal- 

 ensis. The material in the National Museum shows considerable 

 variation in depth of color, the four adult Guatemalan specimens 

 available averaging darker, and the seven from Veracruz and Ta- 

 basco paler. In view of the more extensive series examined by Gris- 

 com, I have followed his findings.

The series of nine specimens was secured as follows: Near Tres 

 Zapotes, March 14 and April 7, 1939, and April 1, 1940 ; lower slopes 

 of Cerro de Tuxtla, May 5, 6, and 9 ; and at about 3,000 feet elevation 

 on Volcan San Martin, April 18 and 21. They are probably much 

 more common than the relatively few that are seen indicate, as they 

 live on the ground in heavy jungle, where they remain almost entirely 

 under cover. About the middle of March at Tres Zapotes they be- 

 gan to call, uttering a whistled note repeated quickly with varying 

 rapidity. They were heard most often on days of rain. They re- 

 sponded readily to a whistled imitation of the call but usually re- 

 mained where they could see but could not be seen. "When they do 

 appear, they walk or run like thrushes on the ground, with raised 

 tail, advancing a few steps and then stopping in shadow or beneath 

 the shelter of leaves to look about. One day at Arroyo Corredor, as 

 I called, one walked out finally around the base of a palm only 10 

 feet away, and as it saw me it flew with a rattling noise of its short 

 wings to a perch on a branch 6 feet from the ground. 



Carriker heard them frequently in May on the lower slopes of 

 Cerro de Tuxtla and on San Martin.

This, the most common of the ant-shrikes, was taken near Tres 

 Zapotes on March 11, 14, 16, and 24, 1939, January 29, February 22, 

 March 14 and 25 and April 5, 1940, at Tlacotalpam on February 7, 

 and in the coastal sandhills near El Conejo on May 15. It ranged in 

 areas of dense brush to the base of the Tuxtla Mountains but did not 

 enter the forest that covers the slopes of this range. As just stated,
