BIRDS OF ARGENTINA, PARAGUAY, URUGUAY, AND CHILE 213 



a ciilmen measurement of 23 mm., comes from near the type-locality, 

 as Mangrullo, Neiiqiien, lies between 80 and 100 kilometers northwest. 

 The culraen in the adult male from Victorica measures 24.5 mm. and 

 in coloration the bird is in agreement with the specimen from Roca 

 and with Hellmayr's description. Since Hellmayr described this 

 subspecies from specimens from Mangrullo, Arroytos, and " Rio 

 Limay " in the Territory of Neuquen, the record from Victorica, 

 Pampa, represents a considerable extension of range. It is probable 

 that Tjerlepsehi is found throughout the belt of open forest that ex- 

 tends from southern San Luis south through Pampa. Conditions 

 in the tract mentioned are more favorable to its existence than in the 

 scanty willows that border the Rio Negro and its tributaries, the 

 Neuquen 'and Limay. 



DYCTIOPICUS MIXTUS MALLEATOR Wetmore 



Dijctioi)icus mixtus malleator Wetmore, Journ. Washington Acad. Sci., 

 vol. 12, Aug. 19, 1922, p. 326. (Las Palmas, Chaco, Argentina.) 



In the Chaco this woodpecker was only fairly common. On July 

 23, 1920, an adult male (type of the subspecies) vvas taken near Las 

 Palmas, Chaco, as it worked busily in a dead fall in dense, swampy 

 forest. A female was shot July 27 as it hopped about in low, scat- 

 tered trees on an open prairie. Another female was shot at the 

 border of forest, near Kilometer 80, Puerto Pinasco, Paraguay, on 

 September 11, 1920. Near Tapia, Tucuman, a female was taken 

 April 8, 1921, and another was observed April 9. The birds when 

 feeding hammer busily at the bark and trunks of trees and in manner 

 suggest small Dryohates. Their call is a low rattle. 



A single specimen from Tapia is slightly more heavily streaked 

 on the breast than others. The present subspecies is easily dis- 

 tinguished from typical mixtus by the heavier black markings on 

 the lower surface and the restriction of the white on the back. 



DYCTIOPICUS LIGNARIUS (BIoHna) 



P/c».s' Llynariiis Molixa, Sagg. Stor. Nat. Cliili, 1782, p. 236. (Chile.) 



Near Concon, Chile, this woodpecker was observed on April 25, 26. 

 and 27, 1921, and a female was collected on April 26. The birds were 

 found in Ioav growths of dense brush and in habits resembled D. 



mixtus. 



VENILIORNIS OLIVINUS (Malherbe)

 p. 67. (Brazil.) 



Woodpeckers of this species, like those of the other two forms 

 of the same genus here discussed, were quiet inhabitants of dense 

 forests where they w^orked industriously, often in concealed situa- 

 tions in which they were discovered Avith difficultv. In mannerisms
