336 Eleventh Supplement to A. O. U. Check-List. Taly 
681. Geothlypis trichas ignota vs. Geothlypis trichas roscoe 
(f. Tenth Suppl., Auk; XVIII, 1901, 318). 
The reasons advanced in support of the proposed change are 
not satisfactory. 
Troglodytes vs. Aylemathrous (¢f. Howr & ALLEN, Bds. 
Mass. 1901, 92; Howe, Auk, XIX, 89). 
Hylemathrous is a pure synonym of Zhryothorus, and has no 
bearing on Zroglodytes. (Cf. OBERHOLSER, Auk, XIX, 1902, 
175-) 
Anorthura vs. 7/og/odytes (of. Howe, Auk, XIX, 1902, 90). 
Anorthura was proposed as a substitute for Zrog/odytes and is 
hence a synonym of it. See avtea, p. 329, where Axnorthura 
is replaced by Olbzorchilus. 
756. Hylocichla fuscescens vs. Zurdus minor DuBols, Syn. 
Av. 1901, 402. 
Turdus minor GMEL. is not regarded as satisfactorily identi 
fiable. 
lll, SPECIES AND’ SUBSPECIES NOT ACCEPTED: 
Tyrannus tyrannus vexator BANGS (cf. MEaRNS, Auk, Jan. 
1902, 72). 
A reéxamination of the case confirmed the Committee in its 
former ruling (cf Ninth Supplement, Auk, XVI, July, 1899, 131), 
that the ascribed characters were too slight for recognition in 
nomenclature. 
Passerculus sandwichensis labradorius Hower, Contr. N. Am.
