BIRDS OF SOUTHERN VERACRUZ WETMORE 295 



more than 20 feet from the ground. He collected three on Cerro de 

 Tuxtla between 1,000 and 2,500 feet elevation on March 29 and April 3, 

 and two on Volcan San Martin between 2,500 and 3,000 feet on April 

 16 and 21. These were breeding birds, active and noisy with a loud 

 call note. On January 18 Carriker secured one near camp at Tres 

 Zapotes and another came into one of the houses. This was during a 

 period of cold and heavy storm, and it was believed that they were 

 wanderers from the mountains, as neither of us found them again in 

 the lowlands. 



The bill in this series of six specimens averages longer than in others 

 but the bird seems to be one that is variable in this respect, several 

 from Teapa in Tabasco being similar. 



Family HIRUNDINIDAE 



STELGIDOPTERYX RUFICOLLIS FULVIPENNIS (Sclater) 



Cotyle fulvipetinis P. L. Sclater, Proc. Zool. Soc. London, 1859, p. 364 (Jalapa, 

 Veracruz). 



The only rough-winged swallow collected is an adult female taken 

 on April 3, 1939, at Tres Zapotes, shot as it passed in flight toward the 

 north. Later that same day I saw a band of 30, and on April 10 I noted 

 another little flock. On March 6 and April 15 I recorded swallows of 

 this species at nesting holes in the river bank at Boca San Miguel but 

 did not have opportunity to collect more for specimens. Carriker 

 noted them near Tlacotalpam and at El Cone jo. 



The one taken has the dark coloration of fidvipennis on the dorsal 

 surface and the sides but has only the faintest trace of buff on two or 

 three of the tiny feathers of the throat. It is thus intermediate 

 toward the more northern birds. 



Stelgidopteryx ridgwayl, marked by very dark back and sides, I 

 believe to be a distinct species, as it has a decidedly heavier bill than 

 the various forms of the ruficollis group.

Carriker found a few over the marshes near Tlacotalpam February 

 7, 1940, and shot a male.
