51. Cyclorhis flaviventris, Lafr. Rev. Zool. 1842, p. 133. 

 Transmitted by Sefior Constancia and Mr. Skinner. 



Fam. VIII. HIRUNDINID^. 



52. HiRUNDo HORREORUM, Barton ; Baird,Rep. p.308.(N.A.) 

 This species, or one very closely resembling it, was observed 



by Salvin near Duenas, in April 1858. 



53. Petrochelidon bicolor (Vieill.). (N. A.) 

 Transmitted by Mr. Skinner. In Mr. Gould's collection. 



54 Petrochelidon thalassina, Sw. Phil. Mag.l827,p. 365. 

 (N.A.) _ 



Early in March great numbers of this beautiful species occur 

 near Duenas, 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. 



55. Atticora ptleata, Gould, P. Z. S. 1858, p. 355. 

 Transmitted by Mr. Skinner. 



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 Duenas. Greater 

 numbers appear in the winter months, but a few are to be found 

 all through the year. 



57. Progne dominicensis (Gm.). 



A skin, transmitted by Mr. Skinner, seems to agree most 

 nearly with this species. 



Fam. IX. AMPELIDiE. 

 Subfam. AmpeliNvE. 



58. Ampelis cedrorum, Vieill. (N. A.) 



Transmitted by Mr. Skinner, and said to be an occasionally 

 abundant winter visitant. Bombycilla maria, Coinde (Grenoble, 

 1857), seems to be nothing more than this bird. 



Subfam. Ptilogonydin^. 



59. Ptilogonys cinereus (Sw.). 



Transmitted by Senor Constancia to the late Mr. Strickland ; 

 and also in Mr. Skinner's series.
