BIRDS OF SOUTHERN VERACRUZ — WETMORE 261 



Carriker secured two, both in heavy forest, the first one at about 

 1,200 feet elevation on Cerro de Tuxtla on April 9, 1940. His assist- 

 ant, Modesto, shot another at about 3,000 feet on Volcan San Martin, 

 April 21.

Streptoprocne zonaris mexicana Ridgway, Proc. Biol. Soc. Washington, vol. 23, 

 Apr. 19, 1910, p. 53 (Rio Seco, near Cordoba, Veracruz, Mexico). 



These interesting swifts were seen at intervals of a few days about 

 Tres Zapotes during the period of my stay, the first being taken on 

 March 11, 1939. I secured others on March 25 and April 10. From 

 three or four to a dozen were observed, usually flying over the milpas, 

 but on April 10 I recorded 30 or more in company. One taken on 

 March 25 was molting. In the air they appear black, but as they turn 

 in swift flight there is occasionally a glimpse of white on the breast. 

 They are known as the golondrina. 



Family TROCHILIDAE 



ARCHILOCHUS COLUBRIS (Linnaeus): Ruby-throated Hummingbird 



Trochilus Colubris Linnaeus, Systema naturae, ed. 10, vol. 1, 1758, p. 120 (South 

 Carolina). 



Two females of this migrant from the north were shot at Tres 

 Zapotes, one on March 20, 1939, feeding through low trees near camp, 

 and the other on March 24, working about flowers in the open. 



CHLOROSTILBON CANIVETII CANIVETII (Lesson) 



Ornismya canivetii Lesson, Histoire naturelle des colibris, Suppl., 1830-31, pp. 174, 

 177, pis. 37, 38 ("Bresil"=Jalapa, Veracruz, Mexico). 



Four specimens were secured near camp at Tres Zapotes on March 

 8 and 31, 1939, and January 29 and March 4, 1940. This was among 

 the less common of the hummers in this region, being found feeding 

 low down at the borders of thickets or in low, open brush. They are 

 quite shy. 



In the original description the type locality is given as Brazil, which 

 is obviously erroneous. In a later account, in the Revue Zoologique 

 for January 1839, page 15, Lesson refers to the two plates Nos. 37 and
