31. CotyLe uropyGiALts, Lawrence, Ibis, 1863, p. 181. 
C. flavigastra, Lawr. (nec Vieill.) J. ce. 1861, p. 317. 
Agrees with Fraser’s Ecuadorian specimens, which Sclater refers 
(P. Z. S. 1860, p. 292) to the eastern C. ruficollis (Vieill.). The 
two species are in fact barely separable, the grey uropygium being 
the only noticeable difference. Cassin, in his List of Lieut. Michler’s 
collection from Darien (Pr. Ac. Nat. Se. of Philadelphia, p. 133), 
refers specimens, doubtless of the same bird, to C. flavigastra, Vieill. 
(=C. rujicollis). 
Hirundo lunifrons and Progne chalybea also occur (vide Law. 1.¢.). 
As Progne dominicensis occurs in Costa Rica and Ecuador (Sclater, 
P. Z.S. 1860, p. 292), it is probable that this is the bird referred 
to as P. chalybea, both by Lawrence (/. c.) and by Cassin (Pr. Ac. 
Nat. Sc. Phil. 1860, p. 133). 
Fam. VirEoNID#. 
32. VIREOSYLVIA ALTILOQUA (Vieill.). 
The occurrence of this Antillean species on the continent is rather 
remarkable ; but there seems no doubt about the identity of the skin 
transmitted by Mr. M‘Leannan with Jamaican examples in Sclater’s 
collection: 
33. HyLoruitus viripiritavus, Lawr. /. ¢. vii. p. 324. 
A distinct species, with the bill rather short and stout. 
34. HyLorHILus CINEREICEPS, Scl. 
H. pusillus, Lawr. 1. ¢. vii. p. 323. 
We are unable to confirm Mr. Lawrence’s H. pusillus as distinct 
from the Mexican and Guatemalan bird which we suppose Mr. 
Lawrence to mean by “ H. plumbiceps, Sclater.’”’ All the distine- 
tions pointed out between birds from either locality can be shown 
to exist in northern specimens, as well in size as in coloration. 
Mr. Lawrence includes in his lists, . c., Vireo flavifrons, Vieill., 
Vireosylvia flavoviridis, Cass., V. bogotensis, Bryant’, Hylophilus 
aurantiifrons, Lawr., and Vireolanius pulchellus, Scl.

Dacnis cerebicolor, Lawr. Aun. L. N. H.N. Y. vii. p. 291. 
If referred to either of the allied species, this bird must go to D. 
cayana; but the more purple colouring of the blue parts render it 
easily distinguishable from this bird.
