"\^"HEy in Tenasserini the late Mr. Davison observed several specimens of a Rock-IMartin 

 about the inaccessible precipices on the eastern side of Mooleyit, near its summit. 

 Mr. Hume adds a note : — " He thought it was exactly like C. concolor, but that species 

 is scarcely likely to have occurred there." It "would seem, however, from subsequent 

 events that Mr. Davison was quite right in his identification of the species, for Mr. Eea 

 procured a couj^le of specimens on the 20th of March at the top of Mooleyit, as recorded 

 by Count Salvadori. 



The following additional notes on the nesting of the species have been published 

 since our accotuit of the bird, in Mr. Gates's edition of Mr. Hume's ' Xests and Eggs of 

 Indian Birds ' : — 



"Major C. T. Bingham writes, from Allahabad : — ' Gn the 13th Gctober I found a 

 nest with two eggs. A mud cup, stuck against a niche in the ruins of an old temple, 

 31 inches in depth outside, 1 in depth inside, lined with a few straws and feathers. 

 Eggs pale pinky white, blotched rather than speckled with tiny marks of grey and 

 purple and sepia.' 



" Colonel Butler writes : — ' The Dusky Crag-Martin breeds at Mount Aboo in June 

 and July, on the sides of cliffs and in hollow rocks, sticking the nest to the wall, as do 

 others of the tribe. The nest is usually a half-open cup at the top, similar in composition 

 and appearance to the nest of Ulnindo filifera. 



" ' On the 26th of August, 1876, I found a nest in Deesa similar to tiic one already 

 described, but built against a wall under the eaves of a building in tlie European 

 barracks. It contained two nearly fresh eggs. Another nest in Deesa, in a similar 

 situation, contained three fresh eggs, on the 21th of Septembei", 1875. xinothcr nest on 

 a beam in the verandah of the regimental school, Deesa, 5th Gctober, 1^70, contained 

 tliree fresh eggs.' 



" Subsequently he wrote from Belgaum : — ' Belgaum, 13th July. 1^70, three fresh 

 eggs; 11th August, three fresh eggs; 15th August, two fresh eggs; 29th August, tlircc 

 fresh eggs; 21st Eebruai-y, 1880, three fresh eggs ; 15th Marcli, three fresh (>ggs.' 



" My friend Mr. Benjamin Aitken favours me with (lie loUowiim- imlc: — 'These 

 birds may be seen wherever there is a range of cliffs or a row of (huk walls, provided the 

 place is not much frequented by men; and they always choose the shady side, as far as
