DESCRIPTIONS OF FIVE NEW
INDO-CHINESE BIRDS

BY OUTRAM BANGS AND JOSSELYN VAN TYNE

The five birds here named were secured by the members of the
William V. Kelley-Roosevelts Asiatic Expedition of Field Museum
of Natural History, Chicago, the Indo-China division of the expedi-
tion being under the leadership of Harold J. Coolidge, Jr. The large
collection of birds obtained on this expedition is in our hands and
we hope soon to publish a detailed account of it in a later number
of Field Museum publication.

The present paper is a preliminary one containing only descrip-
tions of some new forms.

Garrulax erythrocephalus hendeei subsp. nov.

Type from Chapa, Tonkin. No. 68007 Field Museum of Natural
History. Adult female. Collected February 15, 1929, by R. W.
Hendee. Orig. No. 6.

Characters. — Of the eight forms that Stuart Baker (Fauna British
India) considers geographical races of Garrulax erythrocephalus the
new form needs comparison only with melanostigma Blyth, from
which it differs in having the back slightly grayer, the throat duller
reddish brown, and the sides of the neck and the entire chest strongly
"scaled" — the feathers of these regions having pale gray edges and
dusky centers. Wing of type, 95; tail, 97 mm.

This well-marked form is named for the able young naturalist
Russell W. Hendee, whose death of tropical fever was a sad blow to
his fellow members of the expedition.

Cursonia crispifrons saxatilis subsp. nov.

Type from Nam Na River at Bac Tan Trai, Tonkin. No.
68008 Field Museum of Natural History. Adult male. Collected
February 26, 1929, by J. Van Tyne. Orig. No. 430.

Characters. — Differs from Cursonia crispifrons crispifrons (Blyth)
of the limestone ranges of Tenasserim in being gray in general
coloration instead of olive brown. Upper parts grayish olive brown,
the dark edges of the feathers deep black. Lower parts: throat
white, heavily striped with deep black, breast and belly dark gray.
Wing, 75; tail, 74 mm.

This very gray and black form was found only on the limestone
hills whence came the type. Several were shot there by Mr.
Coolidge but all but the type were lost in the holes in the rocks
into which they fell.

Schoeniparus rufogularis kelleyi subsp. nov.

Type from Phuoc Mon, Quangtri, Annam. No. 68009 Field
Museum of Natural History. Breeding male. Collected January
30, 1929, by J. Van Tyne. Orig. No. 167.

Characters. — A very distinct form, differing sharply from S. r.
major, S. r. blanchardi, and S. r. stevensi in having the throat band
broader and deep chestnut in color — very much darker than in any
of the other known forms. The head and whole upper parts are
much darker than in any of the other races. Wing of type, 66;
tail, 50 mm.

Named for Mr. William V. Kelley, who financed the expedition.

Alcippornis poiocephala alearis subsp. nov.

Type from Muong Moun, Tonkin. No. 68010 Field Museum of
Natural History. Adult male. Collected March 29, 1929, by J. Van
Tyne. Orig. No. 921.

Characters. — Most nearly like Alcippornis p. magnirostris
(Walden) and as in that form with sooty brown coronal stripes and
grayish brown head (thus differing from Alcippornis p. haringtoniae
Hartert). From Alcippornis p. magnirostris the new form differs in
its darker, less olive brown back; duller, less cinnamon-rufous rump
and outer edges of wing feathers; and in its more cinnamon-rufous
under parts. Wing of type, 67; tail, 60 mm.

Phylloscopus pernotus sp. nov.

Type from Muong Yo, Laos. No. 68011 Field Museum of
Natural History. Adult female. Collected May 19, 1929, by J. Van
Tyne. Orig. No. 1734.

Characters. — Somewhat similar to Phylloscopus trivirgatus ricketti
(Slater) but smaller, and breast and belly white instead of yellow.

Upper parts rather duller olive green than in Phylloscopus t.
ricketti and dark head stripes duller — olivaceous dusky instead of
black. Lower parts very different; throat and under tail coverts
yellow, breast and belly white, becoming grayish on sides. Wing,
50; tail, 35.5 mm. (the wing in a long series of Phylloscopus t. ricketti
measures 53 to 56 mm.).
