it being Duehas, nearly 5000 feet above the sea. Mr. R. Owen forwarded the eggs from 

 San Geronimo. Capt. Dow procured it at Acajutla in the State of San Salvador, and 

 Mr. Salvin noticed the species at La Union. 



Mr. Dyson forwarded specimens from Honduras, where also Mr. G. Whitely met 

 with it. Mr. G. C. Taylor writes from the same country : — " Swallows were common, 

 especially at Comayagua and in the neighbourhood of churches. I shot one on the 

 wing, while standing in the Plaza, in front of the Cathedral in Comayagua, to the great 

 astonishment of many of the inhabitants, who had evidently never before seen anything 

 shot while in motion. It measured 7 inches in length, and 13| in extent." In Costa 

 Rica it has been sent from San Jose by Hoffmann, and Von Frantzius states that 

 it occurs mostly in the towns. Arce sent specimens from Nicoya, where Mr. Nutting 

 also found it abundant. M'Leannan procured it near Lion Hill Station in Panama, 

 and Arce on the Volcano of Chiriqui. 



In Colombia Mr. Wyatt states that he shot immature specimens at Catamucho, 

 in the Magdalena valley. Mr. Salvin met with it at Remedios, in Antioquia, and 

 a specimen procured by Mr. L. Eraser at Esmeraldas, in Ecuador, is in the Sclater 

 Collection. We have not seen any examples from Venezuela, though the species 

 doubtless occurs in that country, and a specimen from Trinidad is in the British 

 Museum. Throughout Guiana it is also dispersed, Mr. C. Bartlett having procured it 

 at Albina, in Surinam, and Mr. "Whitely having sent a considerable series from Bartica 

 Grove, in British Guiana. 



Mr. Wallace's collection contained specimens from the island of Mexiana and from 

 Para. Writing from the latter place, Mr. E. L. Layard says : — " I first saw this large 

 Swallow on Christmas-day. A little flock of them were flying to and out of a hole in a 

 hollow tree in the square near my house ; some of them carried dry grass bents, appa- 

 rently, and portions of soft lichens gathered from trees. On the 28th I shot one, a 

 female, with the ovaries much distended. No others were about that day ; but I 

 subsequently procured them in the same locality, and at a farm-house near Para. They 

 perch readily and habitually on trees." 



Mr. Edward Bartlett met with this species in many places in Eastern Peru, viz. at 

 Xeberos, Urimaguas, Chyavetas, and Camiraros, and he says that it " breeds like a Wood- 

 pecker, in holes and trunks of trees." 



Prince Maximilian does not apparently distinguish between the ordinary P. chalybea 

 and the larger race, P. domestica. He says " it is the commonest Swallow in Brazil, where 

 it affects human habitations, after the manner of the House-Martin and Swallow of 

 Europe. Like these, it has a swift and graceful flight, and they are fond of perching 

 on lofty buildings and the crosses on the churches, where whole rows of them may be 

 seen. In the districts away from mankind, and on the remote sea-coast, as, for instance, 

 between the estuaries of the rivers Doce and Biacho and other places, where there are 

 rocks in the sea, these Swallows doubtless nest in the clefts of some of the ledges ; but 

 whether they do so in the holes of the clay-built walls, I cannot affirm for certain.
