Transmitted by Senor Constancia and Mr. Skinner. 
Fam. VIII. HIRUNDINLDiE. 
52. Hirundo horreorum, Barton; Baird,Rep. p.308. (N. A.) 
This species, or one very closely resembling it, was observed 
by Salvin near Duefias, in April 1858. 
c' 53. Petrochelidon bicolor (Vieill.). (N. A.) 
Transmitted by Mr. Skinner. In Mr. Gould's collection. 
S 54. Petrochelidon thalassina, Sw. Phil. Mag. 1827,p.365. 
(N.A.) 
Early in March great numbers of this beautiful species occur 
near Dueiias, where they remain but for a short time; during 
that time they are to be found flying over the open land to the 
south of the lake. 
k/ 55. Atticora pileata, Gould, P. Z. S. 1858, p. 355. 
Transmitted by Mr. Skinner. 
S 56. Cotyle serripennis (Aud.). (N.A.) 
In a gorge on the River Guacalate this Swallow is especially 
abundant, but it is also found elsewhere about Dueflas. Greater 
numbers appear in the winter months, but a few are to be found 
all through the year.

A skin, transmitted by Mr. Skinner, seems to agree most 
nearly with this species.
