The Jamarysinho bird has the foreneck tinged with pale yellow, and the 
upper tail-coverts deep orange with dark red tips ; while in the Marmellos specimen 
the former is white like the throat, and the upper tail-coverts are sulphur-yellow 
with the apical portion light orange-yellow. Similar variation is to be observed 
in Peruvian birds,

Ramphastos osculans Gould, Proce. Zool. Soz. Lond. iii. 1835. p. 156 (1835.—* in Brasilia,” type in 
the Vienna Museum, coll. Natterer [cf. Monogr. Ramph. 1st edit. pl. 5], sc. Rio Madeira: 
Ribeirao, Borba *) ; Pelzeln, /.c. p. 234 (Ribeirao, Borba). 
Right bank: Borba, Ribeir&o (Natterer). 
Three specimens, including the type, all from Borba, were kindly lent me 
by the authorities of the Vienna Museum. After comparing them with several 
skins of FR. culminutus, | must confess that I am rather doubtful about the dis- 
tinctness of FR. osculans. The three examples of the latter differ only by having 
the throat, foreneck, and cheeks more or less deeply yellow, while these parts in 
LR. culminatus are pure white, sometimes with a pale yellow tinge on the lower 
foreneck. In other respects, notably in the shape of the bill (culmen bounded 
by a distinct furrow on each side), the two supposed “species” are practically 
identical. Pelzeln (dc. footnote 1) has already called attention to the great 
variation in the coloration of the throat, etc., and upper tail-coverts, as shown by 
Natterer’s series. In the three skins before me the colour of the upper tail-coverts 
varies from sulphur-yellow to scarlet with orange bases, and a similar variation 
in 2. culminatus is mentioned above. 
What &. osculans really is cannot be decided with the limited material at 
our command. The so-called ‘“ oseulans” from the “ Rio Negro” and Munduapo 
(Orinoco) should also be compared with those from the Rio Madeira. ]

Specimens from Borba, as well as others from Para, Maranhiio, and Itaitiba 
(Rio Tapajéz), agree with South Brazilian examples. The northern form, P. aracari 
atricollis (P. L. 8. Mill.) (aracari of Gould, Sturm, Sclater, etc.), with broad black 
culminal stripe, is apparently confined to the Guianas. |
