38 cited above, gives the description again, with something of the 

 habits as observed by DeLattre, and says "Elle est rare aux alentours 

 de Jalapa," which fixes the type locality as I have listed it. Lessors 

 further statement that "M. DeLattre a tue une femelle a Kakamoukho, 

 au Mexique" probably refers to Chlorostilbon auriceps, which is the 

 related species found near Mexico City. 



ANTHRACOTHORAX PREVOSTII PREVOSTII (Lesson) 



Trochilus prevostii Lesson, Histoire naturelle des colibris, Suppl., 1830-31, p. 0*, 

 pi. 24 (locality unknown 88 ). 



The only specimen is a female that I shot on March 31, 1939, near 

 Tres Zapotes after it had darted at a becard resting in an open tree 

 top and then perched nearby. I had seen one in this same locality a 

 few days earlier, and recorded another near Arroyo Corredor on April 

 12. They are robust, heavy-bodied birds of rapid flight.

The white-bellied emerald was one of the more common hummers, 

 though Carriker noted that it may not be resident here, since he did 

 not record it until February 28, 1940, after which it was widely dis- 

 tributed. I found the birds in the open, or at the border of thickets. 

 Specimens were taken at Tres Zapotes on March 7, 14, and 27, 1939, 

 February 28, March 15 and 16, and April 5, 1940, at Hueyapa May 15, 

 and on the Cerro de Tuxtla on March 13. Carriker noted them at 

 El Cone jo near the coast in May.

 April 5 and May 3, 1940; Hueyapa, March 14 and 25, 1940; and 600 

 feet elevation on Cerro de Tuxtla, April 3, 1940. There are other

 at Tlacotalpam on May 28 and 29, San Andres Tuxtla on May 10, 

 and Catemaco on May 4, 1894. 



EiefTer's hummer is a bird of strong, robust form that, with loudly 

 humming wings, feeds around flowers in open places bordering areas 

 of second growth forest, or penetrates the monte itself to range from
