142 Zoological Society : — 



North America. Through South America they range down to the Rio 

 de la Plata, but on the western coast I am not aware that the}^ have 

 been observed nearly so far south. M. d'Orbigny met with but one 

 species * at all on the occidental slope of the Andes ; Tschudi men- 

 tions but three or four as occurring in the vicinity of Lima, on the 

 coast-region of Peru. 



Subjoined are the specific characters of five species occurring in 

 my list, of which accurate descriptions have not yet been published. 



1. Arremon axillaris, Sclater. A. siqu'a oUvaceo-viridis ; 

 capite atro ; snperc'diis productis albis ; vitta verticali et cer- 

 vice jjostica cinereis : suhtus niveus, lateribus cinerascentibus ; 

 macula uti'inque co'vicali vittam quasi imperfectam formante, 

 mentoque summo atris ; remigibus rectricibusque nigricantibus : 

 tectricibus alarum majoribus Jlavo-olivaceis, minoribus et axillis 

 Icete Jlavis : mandibula superior e nigra, inferior e flav a : pedi- 

 bus dare brunneis. 



Long, tota 5*2, alse 3"0, caudse 2*0 poll. Angl. 

 Avis junior. Semitorque collari vix conspicuo. 

 Hub. In Nova Grenada. 



Obs. Species Arremoni seniitorquato maxime affinis, sed hujus 

 axillis olivaceis, illius Isetissime flavis. 



2. Ramphocelus DORSALis, Bp. MS. $ Coccineus : dorso 

 medio obscurius coccineo : alis caudaque nigris : rostra nigro, 

 mandibula inferiore basi Icete alba. 



5 Fusco-brunnea : alis caudaque nigricantibus : uropygio et 

 ventre toto erubescentibus : rostro briinneo. 



Long, tota 7'0, alse 3*2, caudse 3*2. 



Hab. In imp. Brasiliensi. 



Obs. R. brazilio maxime affinis at dorso medio obscurius coccineo. 



I should hardly have ventured to have separated this species from 

 R. brazdius, from which it only differs, so far as I can make out, in 

 the patch of darker colouring in the middle of the back ; but as the 

 Prince Charles Bonaparte has done so, and his MS. name has 

 attained wide circulation on the MM. Verreaux's labels, I think it 

 best to give a ])ublished description of the grounds of the alleged 

 specific difference. However, M. Jides Verreaux, — a good authority, 

 — considers the two species truly distinct, and has assured me, if I 

 recollect right, that he has seen and shot them both frequently at 

 Rio and Pernambuco. 



3. Buthraupis chloronota, Sclater. B. supra viridis ; pileo 

 cccrideo : alis caudaque nigris, illarum tectricibus minoribus 

 ccEruleis ; majoribus et secondariis viridi limbatis : subtus 

 jlavus, crisso saturatiore : gutture toto atro : rostro pedibusque 

 nigris. 



* The Tanagra striata, Gm., in the ravines of Palca in Peru, 18° S.L. M. d'Or- 

 bigny attributes a wide range to this species, which he says occurs besides in the 

 Banda Oriental, near Monte Video, at l3ucnos Ayres, near La Paz, and in the 

 provinces of Yungas, Sieasica, Cocliainbainba, Valle Grande, and Chiquisaca in 

 BoUvia. (Voy, p. 272.) But, qucRre, does he not confound with T. striata, 

 Tschudi's 2\ frugilegus }
