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 distinguished
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 situations
in which they were discovered Avith difficultv. In mannerisms
