NOTHOPROCTA PERDICARIA PERDICARIA (Kittlitz)
Crypturus perdicarius Kittlitz, Mem. Acad. Imp. Sci. St. Petersbourg,
Divers Savan.s, vol. 1, Livr. 2, 1830. p. 193, pi. 12. (Valparaiso, Chile.")
A female taken at Concon north of Valparaiso, Chile, on April
27, 1921, was prei^ared as a skin, Avhile another, secured at the same
time, was preserved as a skeleton. Conover-^ has shown that the
tinamou of southern Chile differs from that of more northern locali-
ties in darker coloration and more brownish upper parts, with
undersurface clay color instead of gray, and has named it N. f.
sanhorni (type locality Mafil, Valdivia).
Conover considers Nothoprocta coquimbica Salvadori,^* named
from a bird taken at Coquimbo by Doctor Coppinger, in the month
of June, indistinguishable from true perdicaria. According to the
ranges assigned by Salvadori perdicaria is found in northern and
central Chile, while coquimbica occurs in South Chile.^^ Mani-
festly the ranges as given are interchanged as Coquimbo lies 350
miles north of Valparaiso. The bird from Concon, while coming
from within a few miles of the type locality of perdicaria^ has the
breast decidedly grayer than a small series of old skins in the
United States National Museum, from near Santiago, Chile, in
this resembling the description of coquiniMca, but, on the other
hand it is blacker above, with paler, browner markings than is
shown in the plate of coquimbica given by Salvadori.
On April 27 I encountered several of these tinamou in a steepsided
brush-clothed gulch in the rolling hills, south of the mouth
of the Rio Aconcagua at Concon. Some ran aside, as I approached,
to hide in the brush, while others rose with excited whistling calls
and dashed away behind cover of trees. Others were noted on
April 28. In the female bird noted above, the maxilla, save on the
posterior cutting edge, was fuscous-black; remainder of maxilla
and mandible drab-gray, with the tip of the mandible shaded with
fuscous; iris Rood's brown; tarsus and toes slightly duller than
chamois ; nails fuscous.
Tinamou were offered for sale in the markets of Valparaiso in
considerable numbers, and were sold in the streets in pairs by itiner-
ant vendors.
