BIRDS OF AEGENHNA, PARAGUAY, URUGUAY, AND CHILE 193 



A male from near Andarahy has a wing measurement of 167.2 mm., 

 while in three others, with sex not indicated, from the other locali- 

 ties listed, the wing measures 170, 176, and 179.2 mm. 



Hellmayr''^ records the wing of a bird from Bahia as 170 mm. 



A fair series of P. m. siy shows a variation in Aving measurement 

 from 183.5 to 197 mm. The specimens seen are marked as males or 

 do not have the sex indicated. One bird from Santa Catherina, 

 Brazil, has the wing 192 mm.; two males from Fazenda Cayoa, E. 

 Parana, measure 183.5 and 186.8 mm. ; and two from Puerto Pin- 

 asco, Paraguay (both males), 190 and 191 mm. respectively. A 

 bird (male) from Las Palmas, Chaco, measures 196 mm., and one 

 from Corrientes 197 mm. Four males from Puerto Suarez, Bolivia, 

 range from 187.1 to 193 mm. Another from Santa Cruz, Bolivia, 

 measures 185.8 mm. 



P. m. lacerus Heine from Tucuman is said to be larger and darker 

 than siy. A male seen in the Field Museum (ISTo. 48990) from Metan, 

 Salta, is probably best referred to this form since it has a wing' 

 measurement of 202 mm., though it is no darker than P. m. siy. 



Pionus m. sly was found near Las Palmas, Chaco, from July 14 

 (when a male was taken) to July 31, 1920. At Puerto Pinasco, 

 Paraguay, on September 1 it was common on the hill at Kilo- 

 meter 25 (specimen), and at Kilometer 80 was recorded from 

 September 13 to 20 (a male shot September 15), Several were seen 

 at Kilometer 200 on September 25. The birds ranged through the 

 forest in little bands that were seen frequently in swift flight to 

 water, or from one tract of monte to another. Their passage was 

 heralded in most cases by strident shouts of chulp chulj> that were 

 redoubled when one of their number chanced to receive an injury. 

 On the wing they appear very dark. 



The Anguete Indians called them yeht a flllC puV.

 Province Coehabamba, Bolivia.) 



These little mountain parrakeets were recorded first on Marcli 13, 

 1921, on the slopes above the city of Mendoza, when by follov/ing 

 back on the line of flight of a small flock we found a water hole, 

 perhaps the onlj^ one in an otherwise wholly arid tract. On March 

 19 near El Salto, at an altitude of nearly 2,000 meters above Pofcreril- 

 los, Mendoza, these parrakeets were common. Here they ranged 

 over the hills in small bands that fed in berry bearing bushes, or 

 descended to search for fallen fruit in the grass belov\\ The birds 

 were highly social and Avere foimd always in parties. Their flight
