BIRDS OF SOUTHERN VERACRUZ — WETMORE 255 



norio, northwestern Costa Kica. 0. I. carrikeH differs from these in 

 being definitely paler above, with the crown, hindneck, and upper back 

 lighter, brighter green, the center of the back and the scapular area 

 lighter, more purplish, the wing coverts, tail, lower back and rump 

 lighter, the sides and flanks paler brown and the under tail coverts 

 whiter. In addition, the black streak on the malar region is decidedly- 

 wider and heavier. 



OREOPELEIA MONTANA (Linnaeus) : Ruddy Quail-dove 



Coluniba montana Linnaeus, Systerna naturae, ed. 10, vol. 1, 1758, p. 163 

 (Jamaica). 



Near Tres Zapotes we had occasional glimpses of pigeons in the 

 woodlands that we thought were this species. Carriker finally 

 secured a breeding male between 800 and 1,500 feet on Cerro de 

 Tuxtla on May 9, 1940. 



Family PSITTACIDAE 



ARATINGA ASTEC ASTEC (Souance) 



Conurus astec Souance, Rev. Mag. Zool., vol. 9, 1857, p. 97 (Mexico). 



These parakeets ranged in pairs and small bands of six to a dozen 

 individuals through woodland and second growth from Tres Zapotes 

 and Hueyapa across to Tapacoyan. Their high-pitched chattering 

 calls were heard regularly, and the birds themselves were seen con- 

 stantly, sometimes at rest and sometimes on the wing. Seven were 

 taken on March 8 and 18 and April 10, 1939, and on February 23, and 

 March 8 and 14, 1940. 



AMAZONA ALBIFRONS NANA Miller 



Amazona albifrons nana W. DeWitt Miller, Bull. Amer. Mus. Nat. Hist., vol. 

 21, 1905, p. 349 (Calotmul, Yucatan). 



Carriker, who collected five specimens, found these parrots more 

 common than the larger species in the region between Tres Zapotes 

 and Boca San Miguel, though the previous year I saw few. The 

 five taken, four males and one female, vary in wing length from 160 

 to 169 nun. and so fall with the small race described originally from 

 Yucatan, marking an extension of range. 



According to specimens that I have examined, in Amazona albi- 

 frons albifrons the wing varies from 172 to 189 mm., while in A. a. 

 nana it ranges from 154 to 170 mm. The smaller race averages slightly 

 paler, more yellowish green, though this distinction is indefinite. I 

 have seen one specimen from Apazote, Campeche, with the wing 175 

 mm., but all others fall within the limits assigned above.
