STIERLING’S GROTJND-THRUSH.
Geocichla litsitsiru-pa stierlingi, Reichenow, Orn. MB. viii. p. 5 (1900).
G. similis G. litsitsirupa, sed pectore rufescenti-flavo lavato, et subalaribus saturatius cinnamomeis distinguenda.
T his is a form of G. litsitsinipa, which inhabits South Africa below the Zambesi, and the occurrence
of G. stierlingi at Iringa in Uhehe, German East Africa, is interesting enough, though it does not
seem to be a very distinct species. I t is distinguished from the typical G. litsitsirupa by its shorter
bill, by its breast being more strongly washed with yellowish-red, and by the darker tone of the
yellowish-red under wing-coverts. The bill is black, with the lower mandible yellowish at the base
and blackish at the tip ; the feet yellowish-red.

ICELAND REDWING.
Turdus coburni, Sharpe, Bull. B. O. C. xii. p. 28 (1901)7
Turdus iliacus coburni, Haase, Om. MB. x. p. 79 (1902).
T. similis T. iliaco, sed suprk pallid^ grisescens, striolis pectoralibus pallide griseis, minime nigris, et hypochondriis
pallide cinnamomeis^ minime ferrugineis, distinguendus.
M r . F . C oburn, a well-known naturalist of Birmingham, visited the north of Iceland in 1 8 9 9 , and
found there nesting many interesting species of birds, such as the American Wigeon {Mar^ca
americana). Amongst others he procured three specimens of a Redwing which differed so mrnch
in the pale colour of the breast-stripes and the pale cinnamon flanks, that I have described them as a
distinct species. Whether this Redwing is resident in Iceland all the year, or whether it migrates,
we have as yet no information, but it is probably the species which nests in the Faroes, as recorded
by Mr. Knud Andersen, near Thorshavn (Orn. MB. p. 79). I)r. Haase (I. c.) has drawn attention to
the migratory habits of Turdus iliacus in the Faroes, and has given some interesting notes on the
subject (£. c. pp. 79, 80). ■

Turdus viscivorus, Erlanger, J . f. O. 1899, p. 248.
Baron E rlanger separated the Mistle-Thrush from Tunis as a distinct pale race ; but he has more
recently come to the conclusion that it is not to be separated from T. mscivorits, though it is very
pale in coloration.
HYLOC ICHLA.
T he Dwarf Thrushes of America are considered by Mr. Oberholser to constitute a genus distinct
from Turdus (which should be restricted to the Old World), on account of their longer tarsus and
more depressed bill. They should be placed under Baird’s genus Hylocichla, rand the A. O. U.
endorses this view (cf. Auk, xix. p. 330).

M r. Osgood proposed to separate the Hermit-Thrush from the coast of British Columbia and
S.E. Alaska from true T. aonalaschJcce. The Committee of the A. O. U., however, have decided
that it is not distinguishable (cf. Auk, xix. p. 337).

T his race, from Monterey, has been separated by Mr. Grinnell, who is also inclined to allow
T. verecundus and T. sequoiensis to be recognizable races. The A. O. U. has not yet pronounced
judgment on this form (Auk, xix. p. 342).
