They were noisy and conspicuous through March and early April, 

 evidently the mating season, and then became more retiring. Some- 

 times during light fogs early in the morning I saw them resting 

 in the tops of low trees over the trails, but more often noted them 

 moving under cover in the thickets, or flying with bounding flight 

 through the forest, the green back and black head showing con- 

 spicuously. 



SALTATOR MAXIMUS GIGANTODES Cabanis 



Saltator gigantodes Cabanis, Museum Heineanum, vol. 1, Oct. 1851, p. 142 

 (Mexico). 



Our specimens were secured near Tres Zapotes on March 23 and 

 28, 1939, and January 17, and 20 and March 7, 1940. This was de- 

 cidedly the rarest of the three kinds of saltators around Tres Za- 

 potes. In general habits it suggested the larger Saltator atriceps 

 suffuscm, but lived in heavier forest and kept more closely under 

 cover. Most of the few that I saw were in leafy tree tops where 

 they fed early in the morning. One came to sing in a low tree near 

 the border of our camp clearing where I sat writing, the loud, 

 slurred notes being entirely different from those of the other species, 

 suggesting in part the song of a Cyclarhis and in part the notes of 

 an oriole. 



SALTATOR COERULESCENS GRANDIS (Lichtenstein) 



Tanagra grandis Lichtenstein, Preis-Verzeichuiss mexicanischer Vogel, 1830, p. 2 

 (Jalapa, Veracruz). 



Our specimens were taken at Tres Zapotes on March 14, 21, and 25, 

 1939, and January 25, and March 4, 5, and 8, 1940, and at Tlacotal- 

 pam, February 7, 9, 15, and 19, 1940. The species is one of wider 

 general distribution than the other two as is shown by its occurence 

 in the scattered thickets about Tlacotalpam. Carriker noted it also 

 among the dunes at El Conejo. 



Near the Tres Zapotes camp these birds were common, being re- 

 corded daily, apparently occurring in greater number than S. a. suf- 

 fices. They were found in the brush bordering old fields and were 

 shy and retiring. In March and early in April I heard them sing- 

 ing a clear, loud warble suggestive of a grosbeak, with occasional 

 ringing notes that bring to mind the ecstasies of the northern bobo- 

 link. 



CARYOTHRAUSTES POLIOGASTER POLIOGASTER (Du Bus) 



Pitylits poliogaster Du Bus, Bull. Acad. Roy. Sci. Belgique, vol. 14, 1847, p. 105 

 (Guatemala). 



Specimens were secured by Carriker at Tres Zapotes on February 

 23, and March 3 and 18, and on Cerro de Tuxtla on March 13, and
