GEOCICHLA LEUCOL^MA, Salvad.
SAXVADORI’S GROUND-THRUSH.
Geocichla leucolcema, Salvad. Ann. Mus. Civic. Genov. (2) xii. p. 13*5 (1892).
G. tectricibus alarum mediis et majoribus albo terminatis: pileo et collo postico castaneis : dorso rufescenti-
brunneo : bypochondriis nigro maculatis : regione parotid! nigr&.
T his species was discovered by Dr. Modigliani in June 1891 at Bua-Bua, in the island of Engano, on
the west coast of Sumatra, about 200 miles north-west of Java. In the following year it was
described by Count Salvadori as Geocichla leucolcema.
It belongs to the group of Ground-Thrushes containing G. erythronota, G. interpres, &c., but is
easily distinguished from all of them by the black ear-coverts and sides of face. It appears to be
most closely allied to G. interpret, as might have been expected from its habitat, but it has many
characters in common with G. erythronota.
The type of this species may be described as fo llow sF o r e h e a d and crown chestnut-brown,
shading into orange-chestnut on the nape, but abruptly separated from the rest of the upper parts,
which are russet-brown, most rufous on the upper tail-coverts; lores black; eye-stripe obsolete;
lesser wing-coverts black; median and greater wing-coverts black, with large white terminal
fan-shaped spots; primary-coverts black; tertials russet-brown; secondaries and primaries brown,
margined with russet-brown on the outer webs ; tail-feathers dark brown, the outer pair tipped with
white; ear-coverts black; chin and throat white; cheeks, sides of the neck, and breast black; flanks
suffused with olive-brown and marked with rather obscure crescentic black spots, which extend below
the breast; rest of the underparts white; axillaries black, with white bases ; lower primary-coverts
black; lower secondary-coverts white, with black bases.
Geocichline markings on inner webs of quills, white.
Bill black. Tarsi, feet, and claws flesh-coloured.
Length of wing 3*85 inches; tail 2'55 inches; culmen 0‘67 inch; tarsus 1*22 inch; bastard-
primary projecting beyond the primary-coverts.
The Plate represents two life-sized figures of the type specimen, which was kindly lent to me by
Count Salvadori.
