266 PROCEEDINGS OF THE NATIONAL MUSEUM vol.93 



The black-headed trogon was the most common species around 

 Tres Zapotes, being found in second-growth forest as well as in the 

 virgin timber. Carriker recorded one at 1,200 feet elevation on 

 Cerro de Tuxtla, but he considered the species uncommon over the 

 lower slopes of the mountains. Specimens were taken on March 9 

 and IT and April 12, 1939, and January 18, 22, and 29, February 22, 

 and March 8, 1940, all near camp. The thickened fleshy eyelid is 

 bright light blue in life. In March these birds were calling, and 

 after the middle of the month I heard their notes constantly all 

 through the afternoon as I worked at camp, as well as during the 

 forenoon when I was afield. At this time also they seemed more alert 

 and active, and occasionally one came to shaded perches in small 

 trees outside my door to rest quietly, jerking the tail as it uttered 

 a low cuck. The song is a cooing call that becomes suddenly faster 

 at the end until it resembles a rattle. The natives called trogons 

 mira el sol. 



TROGON MASSENA MASSENA Gould 



Trogon massena Gould, A monograph of the Trogonidae, ed. 1, 1838, pi. 16 

 and text (Guatemala). 



The only specimen obtained is a male, shot by Modesto, Mr. Carri- 

 ker's assistant, at about 1,500 feet elevation on Cerro de Tuxtla on 

 March 19, 1940. The bird was resting rather high in a forest tree. 



This individual apparently is immature, as the breast feathers are 

 gray, barred with grayish black. The wing coverts and secondaries 

 are darker, having less mixture of whitish than others that I have 

 examined with the exception of one skin from Teapa, Tabasco. 



Family ALCEDINIDAE 



MEGACERYLE ALCYON (Linnaeus) : Belted Kingfisher 



Alcedo alcyon Linnaeus, Systema naturae, ed. 10, vol. 1, 1758, p. 115 (South 

 Carolina). 



Several Mere recorded along the river channels between Tlacotal- 

 pam and Boca San Miguel on March 6, and near Tres Zapotes sin- 

 gle birds were observed at Laguna del Tular until March 29, 1939. 

 No specimens were taken, but it is supposed that these were the east- 

 ern subspecies. 



MEGACERYLE TORQUATA TORQUATA (Linnaeus) : Ringed Kingfisher 



Alcedo torquata Linnaeus, Systema naturae, ed 12, vol. 1, 1766, p. 180 (Mex- 

 ico). 



In 1939 I saw these birds along the Rio San Agustin near Boca 

 San Miguel and observed them occasionally about the larger lagoons
