collections, but easily distinguishable by the brighter yellow of the 
under-parts being prolonged over the belly, and the back being 
olive-green and not brown. The beak of the present bird is also 
stouter and the tail longer; but the form otherwise agrees with that 
of B. rufifrons. 
The New-Granadian bird which I referred to B. delattrii in my 
list of Bogotaun birds is clearly a distinct species again, distinguishable 
by its longer wings and the fuller yellow of the body beneath, which 
passes into olive on the sides. I now call this Basileuterus meso- 
chrysus. 
M. Sallé’s specimen of B. delattrii is labelled ‘ Uvero: iris brown,’ 
and is the only example I have yet seen of this bird. 
6. Vireo FLAVIFRONS (Vieill.). 
In fine plumage. Goes as far south as Guatemala. See ‘ Ibis,’ 
1859, p. 12. 
7. PLECTROPHANES MELANOMUS, Baird, Rep. p. 436. 
Two specimens, which, with another Mexican bird in my posses- 
sion from M. de Saussure’s collection, seem to agree with Prof. Baird’s 
characters of P. melanomus. This is the extreme southern point 
that has yet been recorded for a species of this genus.

This beautiful Grosbeak forms the third American species of the 
group. It is easily distinguishable from C. vespertinus and C. 
abeillii by its black cap, white wing-bar, and the white markings on 
the outer tail-feathers. The general structure is that of C. vesper- 
tinus ; the three first remiges are nearly of equal length. The bird 
described by Prince Bonaparte (Consp. i. p. 505) as the young of 
C. vespertinus was doubtless of this species, and there is a specimen 
of it in immature plumage in the British Museum. 
9. CoccoTHRAUSTES VESPERTINUS (Cooper): Baird, Rep. p. 409. 
* I did not expect to find this Western bird ranging so far south- 
wards. 
10. Icrerus PARISORUM, Bp. 
Three examples, all in immature plumage.
