681 ^>. G-eothlypis trichas ignota vs. G eat hi y pis trichas roscoe 

 {cf. Tenth SuppL, Auk, XVIII, 1901, 318). 



The reasons advanced in support of the proposed change are 

 not satisfactory. 



Troglodytes vs. Hykmathrous {cf. Howe & Allen, Eds. 

 Mass. 1901, 92 ; Howe, Auk, XIX, 89). 



Hykmathrous is a pure synonym of Thryothorus, and has no 

 bearing on Troglodytes. {Cf. Oberholser, Auk, XIX, 1902, 



I75-) 



Anorthuravs. Troghniytes {cf Howe, Auk, XIX, 1902, 90). 



Anorthura was proposed as a substitute for Troglodytes and is 

 hence a synonym of it. See antea, p. 329, where Anorthura 

 is replaced by Olbiorchilus. 



756. Hylocichla fuscescens vs. Tardus minor Dubois, Syn. 

 Av. 1901, 402. 



Turdus minor Gmel. is not regarded as satisfactorily identi- 

 fiable. 



III. SPECIES AND SUBSPECIES NOT ACCEPTED. 



lyrannus tyrannus vexator Bangs {cf Mearns, Auk, Jan. 

 1902, 72). 



A reexamination 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. 



Passerciilus sandjvichensis labradorius Howe, Contr. N. Am. 

 Orn. I, Oct. 14, 1 90 1, I. 



Considered to be inseparable from Ammodramus sandzvichensis 

 savanna.
