winter. Several specimens were procured by Mr. and Mrs. Herbert Smith at Chapada, 

 in the province of Matto Grosso, in September and October. The specimens from this 

 expedition in the Salvin-Godman collection are three in number, and they are quite 

 pale, but show the spots on the breast very plainly. All the brown pectoral spots are 

 edged with hoary white like the rest of the under surface, and we believe that it is by 

 the wearing off of these pale edges that the spots are developed in the breeding-plumage. 

 The late Mr. W. A. Forbes met with the species near Pernambuco during his stay 

 there from July to September. Several specimens collected by Wucherer and other 

 naturalists near Bahia are in the Museum collection, and the late Prince Neuwied found 

 the species on the Campos Geraes in the interior of the province of Bahia. 



In Amazonia the species was procured by Mr. Wallace on the Bio Tocantins. "We 

 have already referred to its occurrence on the Bio Negro, as reported by Natterer, who 

 found it common on the right bank in December. Mr. Henry Whitely procured a large 

 series at Yquitos on the Upper Amazons in June, July, and August. Scarcely any of 

 these specimens show a trace of the pectoral spots, and a good many have whitish edges to 

 the feathers of the upper surface. Mr. E. Bartlett found it at Xeberos and on the Upper 

 and Lower Ucayali, where, he states, " it is common, and breeds in large numbers in all 

 the country visited." Three specimens from the Upper Ucayali, now in the British 

 Museum, were procured in May, August, and September respectively. Mr. Stolzmann 

 found this Martin very common at Tumbez, and nesting ; it was not observed south of 

 this place. 



In the Salvin-Godman collection are two specimens from the Santa Bita mountains 

 in Ecuador, received from Mr. Villagomez, and the Sclater collection contains examples 

 from Bogota. In the Magdalena Valley Mr. Wyatt found this species ascending the 

 Cordillera to some 4000 or 5000 feet ; they were nesting at the end of January. Mr. A. 

 Goering procured an example at Puerto Cabello, in Venezuela, in June. 



In the Sclater collection is a specimen from British Guiana, obtained on the Corentyn 

 Biver by Mr. im Thurn. 



The record of localities does not explain where is the winter home of all the indi- 

 viduals which breed in Southern Brazil and the Argentine Bepublic. 



Mr. W. H. Hudson gives a very interesting notice of the species in ' Argentine 

 Ornithology ' : — 



" The Tree-Martin is a very garrulous bird, and no sooner arrives, early in September, 

 than we are apprised of the circumstance by the notes which the male and female 

 incessantly sing in concert, fluttering and waving their wings the while, and seeming 

 quite beside themselves with joy at their safe arrival ; for invariably they arrive already 

 mated. Their language is more varied, the intonation bolder and freer than that of our 

 other Swallows. The length of the notes can be varied at pleasure ; some are almost 

 harsh, others silvery or liquid, as of trickling drops of water ; they all have a glad 

 sound ; and many have that peculiar character of some bird-notes of shaping themselves 

 into words.
