164. HiRUNDo ALBiGULARis, Strick. Southern "Whitc- 

 throatcd SwalloAv. 



A pair of these Swallows fixed a nest on the side of a beam 

 in a deserted building in the town, from Avhich I took three 

 eggs ; the nest was cup-shaped, or rather like a cup cut per- 

 pendicularly down the centre and stuck against the beam ; it 

 was composed of mud and was open at the top, and lined with 

 feathers placed loosely in it. 



The eggs (which I took in December) were much incubated, 

 they measured 9^ lines in length by 7 in breadth, and were 

 white spotted more or less throughout, but especially at the 

 obtuse end, with reddish brown of different shades. 



12. HiRUNDO SEMIRUFA, Suud. Rufous-brcastcd Swallow.

 from Potchefstroom,

 sent to me by Mr. Ayres from Trans-Vaal. — J. H. G.]

 Crane. 



The specimen sent is the cock bird of the pair that bred in 

 a swamp about twenty-four miles from Potchefstroom, and 

 from whose nest my friend Mr. Bodensteiu obtained for me 

 two eggs in December 1871. 



The hen bird this season found another mate and again
