 alls caudaque nigricantibus ; fascia alarum duplici alba : sub- 

 tus 'pallide cinerascens, gutture albo, vent7'e nigricante trans- 

 versim lineato : rostro nigro, mandibulcs inferioris basi albido : 

 pedibus fuscis.

Obs. — Affinis //. Bamblce ex Cayenna, sed crassitie paulo majore, 

 rostro longiore et gula alba dignoscenda. 



CONOPOPHAGA TORRIDA. 



Clare brunneseentl-oUvacea, dorsi plumis nigro partim variegatis ; 

 capite supra, alis efcaudaferruginescenti-brunneis: tectricibus 

 alarum et secundariis extus macula apicali fulvo-flavida orna- 

 tis : 2^h(}na7'um fasciculo p)osfocidari ulbo : subtus dare ferru- 

 ginea, gula et ventre medio albicantibus, hypochondriis et ventre 

 into magisfulvis : mandibula superiore nigra, inferiore cornea : 

 pedibiis pallidis. 

 Long, tota 4'6, alse 2*8, caudee 1*2, tarsi TO. 

 M. Verreaux's collection contained a single specimen of this ap- 

 parently new Conopophaga, not in very good plumage. A more 

 perfect example in the British Museum, which is from Chamicurros 

 in Eastern Peru, has furnished my specific characters. 



This is a typical species of the genus somewhat allied to C. lineata 

 of South-eastern Brazil. 



Grallarta flavirostris. 



Brunnescenti-olivacea, loris et capitis lateribus rufescentibus : 

 subtus alba, pectoris medii et lateralis plumis jjallide rujis, 

 utrinque nigro late limbatis, quasi squamatis ; gidce laterum 

 plumis rufo tinctis, fascia nigricante intus marginatis; tec- 

 tricibus subalaribus pallide rufs ; rostro flavo ; pedibus dare 

 brunneis. 

 Long, tota 4'2, alse 2-7, caudce 1*1, tarsi 0'9, rostri a rictu 0*7. 

 This diminutive Grallaria is very like the Venezuelan bird which 

 I described in the Proceedings for last year (P. Z. S. 1857, p. 129) 

 under the name of G. loricata. Like that, it has a pectoral band 

 formed by the black margins of the pale rufous feathers ; but in the 

 present species the band is much narrower, and the head is not 

 chestnut. 



Grallaria fulviventris. 



Olivaceo-brunnea, pileo obscnriore, alis extus magis rufescentibus, 

 loris albidis : subtus gida et abdomi.ne medio albis, pectore, 

 ventris lateribus et crisso cum tectricibus alarum inferioribus 

 saturate falvis, pectore lineis quibusdam nigris variegato : 

 rostro superiore nigro, inferiore, nisi apice, flavo: pedibus 

 pallide brunneis. 



Long, tota .v."), also 3'2, caudce 1*4, tarsi l"."), I'ostri a rictu 0'95. 



This Grallaria seems to belong to a species distinct from anything
