Synallaxis fiavigularis, Gould, Voy. Beagle, Zool. iii. p. 78, pi. 24 ; Ph. et Landb. Cat. Av. Chil. p. 12. "Synallaxis rufa, Landb. MS.," Scl. P. Z. S. 1867, p. 324. Synallaxis brunnea, Gould, Voy. Beagle, iii. p. 78 (jr.). Supra cineraceo-fusca : alis fusco-nigris rufescente limbatis : remigum parte interiore in dimidio basali et subalaribus fulvis : subtus valde dilutior, pallide ochraceo-cinerea, gula macula rufescente : cauda rectricibus tribus externis omnino rufis, ceteris nigris, parte tertia extus anguste rufo limbata : long, tota 6, ala 2*3, cauda 3. Junior macula gulari caret. Hab. Rep. Argentina, Mendoza (Burm. et Weisshaupt) ; Conchitas near Buenos Ayres and Rio Negro of Patagonia (Hudson) ; Port Desire, Bahia Blanca, and Sta. Cruz (Darwin). Obs. Species a S. modesta rectricibus duabus externis omnino rufis distinguenda. I have skins of this species from the first three localities mentioned, and have examined Darwin's specimens in the British Museum. Amongst the last are typical examples of S. fiavigularis and S. brunnea. Sect. e. Species supra unicolor : cauda graduata acuminata : gula macula lutea. 52. SYNALLAXIS SULPHURIFERA. Synallaxis sulphurifera, Burm. P. Z. S. 1868, p. 636 ; Scl. et Salv. P. Z. S. 1869, p. 632 ; Hudson, P. Z. S. 1872, p. 544. Supra fusca, alarum tectricibus et remigum fascia basali rufis: cauda graduata : rectricibus valde acuminatis, lateralibus rufis : mediis fuscis : subtus alba, gula macula lutea : pectore hypochondriis, crisso, et subalaribus fulvescentibus : long, tota 6, ala 22, cauda rectr. med. 3*2, ext. \ : rostro elongatiore, incurvo. Hab. Rep. Argentina et Patagonia bor.: Buenos Ayres (Burm.) ; Rio Negro (Hudson). This interesting species should perhaps be placed near to S. striaticeps, which it approaches as regards its graduated tail and slightly incurved bill. But it agrees with the last group in having a distinct gular patch. In habits, according to Mr. Hudson, it resembles Limnornis curvirostris rather than its congeners. Sect. /. Species supra unicolor : cauda rotundata : gula macula nulla. 53. SYNALLAXIS PATAGONICA. Synallaxis patagonica, D'Orb. Vov. Ois. p. 249: Hudson. P. Z S 1872, p. 544.
