Birds from South America. 113 
True 7. cana and true T. episcopus seem to be found in 
the same locality, as I have seen specimens of both, evidently 
of the same preparation as the first-named form. 
2. 'TACHYPHONUS INTERCEDENS, Sp. NOV. 
T. cristato affinis, pileo aurantiaco-flavo (nec rubro), colore 
corporis nigrescentiore, plaga gulz flava angustiore et vix 
distincté et uropygio flavo pallidiore distinguendus ; 
alis longioribus. Quasi intermedius inter 7. cristatum 
et T. surinamum esse videtur. Long. alz 84 millim., 
caudee 75. 
Hab. Orinoco district or Trinidad. 
Fam. TRocHILips@. 
3. HyLocHaris CYANEA, subsp. VIRIDIVENTRIS. 
This is a northern form of H. cyanea of Brazil, from 
which it differs im its somewhat more splendid and vivid colo- 
ration. In particular I find the belly to be never mixed with 
grey, as in Brazilian specimens, but of a dark and splendid 
green colour. 
This form I have seen from Venezuela (Merida), Trinidad, 
and the Orimoco district. 
Fam. Picipm. 
4 CENTURUS TERRICOLOR, Sp. NOV. 
Affinis C. tricolori (ex Bogota), sed major, et rostro longiore, 
latiore; capitis lateribus, gula et abdomine toto obscure 
brunneo-olivaceis; ventre medio obscuré rubro (nec flavo- 
rubro) ; tectricibus caudz superioribus inferioribusque 
nigro regulariter fasciatis, primo visu distinguendus. 
Long. alee 108, caudze 60, rostri 24, tarsi 19. 
Hab. Orinoco district or Trinidad. 
5. CELEUS IMMACULATUS, Sp. NOV. 
This form, of which I have only a female in my collection, 
is most nearly allied to C. elegans, from which it seems only 
to differ in having the inner webs of the wing-feathers plain 
yellow, without the black bands or spots to be seen in that 
species. If I do not err, my specimen has the preparation of 
Panama skins (Agua dulce), from which locality, as yet, 
neither C. elegans nor C. castaneus, of Central America, has 
SER, IV—VOL. IV. I
