380 Mr. E. Gibson on the Ornithulogy of [Ibis, 



Cypress adjoining nay house in a way that strongly indi- 

 cated a nest (but which I failed to locate amidst the dense 

 foliage). On the morning of 8 January, after a night's 

 thunderstorm and heavy rain, I saw two adults and what I 

 took to be two full-fledged young in the usual lower part of 

 the Cypress. After that, until 25 February, one bird only 

 continued to be observed in its favourite locality, and ceased 

 to appear after that date. 



25. Progne furcata Baird. Purple Martin. 



AVhen writing on this species in 'The Ibis' (1880, 

 p. 23), under the designation of Progne purpurea Linn., I 

 was actually referring to Progne chalybea Gm. The real 

 furcata is summarizeil in the paragraph which says : — 

 " There were two entirely black specimens which used to 

 appear annually at the head-station ; but I have not seen 

 them for the last year or two." 



Mr. Grant records one which he obtained (the only one 

 observed) in 1909 (' Ibis,' 1911, p. 89). 



On 13 September, 1880, there appeared two. On 16 Sep- 

 tember, 1881, one. On 15 September, 1882, one. A.11 

 the preceding — mine and Mr. Grant's — were in associa- 

 tion with Progne chalybea. With one other exception 

 (18 November, 1899), I have noted none since 1882. 



26. Progne chalybea (Gm.). Domestic Martin. 



To my former notes (' Ibis,' 1880, p. 23, under P. furcata)^ 

 I have only one further observation to add. Mr. Hudson 

 states that it "never breeds in the domed nests of other 

 birds in trees, a situation always resorted to by the Tree- 

 Martin [P. tapera)" referring, of course, to the nests of 

 the Oven-bird {Furnarius rufus). Two such cases, however, 

 have come under my notice, on 5 and 12 November, 1879, 

 which I Hnd jotted down under the remark : " Noticed that 

 a pair of Domestic Martins have taken possession of an 

 Oven-bird's nest, closing up the lower half of the entrance 

 with mud"; and, "another similar case to the preceding- 

 observed."
