Vieillot in his generic characters, but I consider this erroneous, aud 

 believe the former number to be the normai one. 



The present bird seems not uncommon in Bogota coUections, but 

 has probably been liitherto confounded with its several allied species. 



3. Synallaxis mcesta, sp. nov. 



S. olivascenti-brunnea, suhtus paulo dilutior : alis intus nigris, extus 

 castaneis : cauda rufa : loris et gutture albidioribus : tectricibus 

 subalaribus pallide fulvis ; rostro vulido, nigro ; mandibula in- 

 feriore basi albescente : pedibus pallidis. 



Long. teta 5'2, alae 2'5, caudse 2*5. 



The single specimen which I possess of this bird was received frorn 

 MM. Verreaux. It is of a nearly uniform olive-brown, rather Ughter 

 below, particularly on the throat and sides of the head. The chestnut 

 margin of the quills grows narrower towards their apices, learing the 

 dusky black appareut, 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 normai length in my 

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

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



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

 Zool. 1843, p. 290) as frorn this covmtry, I have as yet only met 

 with three, namely, S. gularis, cinnamomeus and unh-ufus, which I 

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

 meus of a Bogota bird of this genus ^vhich I think may possibly 

 be his (S. fuUginosus, and there are examples of the šame 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. Synal,laxis fuliginosa, Lafr. R. Z. 1843, p. 290 ? 



(S. supra rufescenti-brunnea, alis extus paulo clarioribuš, cauda adhuc 

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

 cibus decem, angustissimis et tenuissimis : loris et superciliis in- 

 distincte albidis : infra obscure cinerea, mente summo et ventre 

 albescentioribus : rostro nigro : basi mandibula inferioris albicante ; 

 pedibus validissimis clare brunneis. 

 Long. totą 6'o, alae 23, 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, measuriug only one iuch in length, 

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

 ceedingly narrow, in particular the outer ones, and growfiner towards 

 the extremities. 



This form of SijnaUaxis shows evident rapprochement towards 

 Sylmorthorhynchus.
