Mr. P. L. Sclater on some species of Birds from Bogota. 87 



dusky black apparent, but at their bases extends through both webs 

 and shows itself underneath. The tail is pure rufous and very- 

 short, but I am not quite certain that it is of its normal length in my 

 specimen, there being indications of a state of moult. The bill is 

 rather stronger and more conical than in most species of the genus. 

 Out of the six Synallaxes described by M. de Lafresnaye (Rev. 

 Zool. 1843, p. 21)0) as from this country, I have as yet only met 

 with three, namely, S. gularis, cinnamomeus and unirufuSy which I 

 have been able to identify with certainty. I have, however, speci- 

 mens of a Bogota bird of this genus which I think may possibly 

 be his S. fuUginosuSy and there are examples of the same species in 

 the British Museum. If I am correct in my conjectures, I may 

 remark, that the description he gives of this bird is hardly sufficiently 

 accurate, and I can only refer my specimens doubtfully to his species 

 with the following characters : 



4. Synallaxis fuliginosa, Lafr. R. Z. 1843, p. 290? 



5. supra rufescenti-brunnea, alls extus paulo clarioribus, cauda adhuc 

 clariore, pure hrunnescenti-rufa, scapis plumarum nigris : rectri- 

 cibus decern, angustissimis et tenuissimis : loris et supcrciliis in- 

 distincte albidis : infra obscure cinerea, mento summo et ventre 

 albescentioribus : rostra nigro: basi mandibula inferioris albicante ; 

 pedibus validissimis dare brunneis. 



Long, tota 6 '5, alae 2*3,. caudse 3* 75. 



The tail of this bird is of a clearer and more reddish-brown than 

 the back, with the shafts of the feathers black. The outer pair of 

 rectrices are abnormally small, measuring only one inch in length, 

 the next pair about double that length. The webs of all are ex- 

 ceedingly narrow, in particular the outer ones, and grow finer towards 

 the extremities. 



This form of Synallaxis shows evident rapprochement towards 

 Sylviorthorhynchus . 



5. Anabates RUFiCAUDATUS, Lafr. et d'Orb. Syn. Av. in Mag. 

 deZool. 1838, p. 15. 



I possess a Bogota skin, received from MM. Verreaux, which 

 M. de Lafresnaye has kindly identified for me as being of this 

 species. 



The apical portion of the outer primaries in this bird is blacky 

 which colour gradually diminishes in extent in the succeeding feathers, 

 and is reduced to a minimum in the secondaries, where it only forms 

 a blotch at the ends. The first quill is nearly wholly black, and in 

 those next succeeding the same colour advances far up the stems, being 

 broadly margined outwardly with chestnut, and inwardly with paler 

 cinnamomeous. 



6. Anabates erythropterus, sp. nov. ? 



A. supra pallide brimnescenti-cinereus ; alls extus et cauda tota rufis, 

 remigum exteriorum parte apicali nigra : loris oculorum ambitu
