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 they 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. supra olivaceo-viridis ; 

 capite atro ; super ciliis productis albis ; vitta verticali et cer- 

 vice postica cinereis : suhtus niveus^laterihus cinerascentibus ; 

 macula utrinque cervicali vittam quasi imperfectam formantCy 

 mentoque summo atris ; remigibus rectricibusque nigricantibus : 

 tectricibus alarum majoribus flavso-olivaceis^ minoribus et axillis 

 Icete Jlavis : mandibula superiore nigra^ inferiore Jlava : pedi- 

 bus dare brunneis. 



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

 Avis junior. Semitorque collari vix conspicuo. 

 Hab. In Nova Grenada. 



Obs. Species Arremoni semitorquato maxime affinis, sed hujus 

 axillis olivaceis, illius leetissime flavis. 



2. Ramphocelus dorsalis, Bp. MS. J Coccineus : dorso 

 medio obscurius coccineo : alis caudaque nigris : rostro nigro^ 

 mandibula inferiore basi IcBte alba. 



$ Fusco-hrunnea : alis caudaque nigricantibus : uropygio et 

 ventre toto erubescentibus : rostro brunneo. 



Long, tota 7'0, alse 3*2, caudae 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. brazilius, 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 published description of the grounds of the alleged 

 specific difference. However, M. Jules 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 



cceruleo : alis caudaque nigris, illarum tectricibus minoribus 

 cceruleis ; mujoribus 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 Buenos Ayres, near La Paz, and in the 

 provinces of Yungas, Sicasica, Cochambamba, Valle Grande, and Chiquisaca in 

 Bolivia. (Voy. p. 272.) But, quare, does he not confound with T. striata, 

 Tschudi's T.frugilegiLs}
