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. 4. supra olivaceo-viridis ; 
capite atro; superciliis productis albis ; vitta verticali et cer- 
vice postica cinereis : subtus niveus, lateribus cinerascentibus ; 
macula utrinque cervicali vittam quasi imperfectam formante, 
mentoque summo atris; remigibus rectricibusque nigricantibus : 
tectricibus alarum majoribus flavo-olivaceis, minoribus et azillis 
lete flavis: mandibula superiore nigra, inferiore flava: pedi- 
bus clare brunneis. 
Long. tota 5-2, alee 3:0, caudze 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. 3 Coccineus: dorso 
medio obscurius coccineo : alis caudaque nigris: rostro nigro, 
mandibula inferiore basi lete alba. 
2 Fusco-brunneus: alis caudaque nigricantibus : uropygio et 
ventre toto erubescentibus : rostro brunneo. 
Long. tota 7°0, ale 3°2, caude 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 
Rh. 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. Bururavpis cHLoronora, Sclater. (Pl. LXIV.) B. supra 
viridis; pileo ceruleo: alis caudaque nigris, illarum tectri- 
cibus minoribus ceruleis ; majoribus et secondariis viridi lim- 
batis: subtus flavus, crisso saturatiore: gutture toto atro: 
rostro pedibusque nigris. 
* The Tanagra striata, Gm., inthe 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, gu@re, does he not confound with 7. striata, 
Tschudi’s 7. frugilegus ? 
No. CCLXVI.—Procrexpincs or THE ZOOLOGICAL SOCIETY.
