66. Erythropygia coryph/eus. (Stark, ii. p. 229.) 

 Very common and noisy. 



67. Dicrurus afer. (Stark, ii. p. 265.) 



A pair was seen on the river-bank early in June. 



68. Cotile paludicola. (Stark, ii. p. 283.) 



Very common. It nested in holes on the batiks of dongas, 

 just like the English Sand-Martin. 



69. Cotile cincta. (Stark, ii. p. 284.) 



A number of these Martins appeared about the 19th of 

 April and disappeared again about a week later. 



70. Ptyonoprogne fuligula. (Stark, ii. p. 287.) 



A few pairs of this species frequented some rocky kopjes. 

 They seemed just as active in the middle of the day as in 

 the evening. 



71. Hirundo rustica. (Stark, ii. p. 289.) 

 Very common, but departing early in April. 



72. Hirundo albigularis. (Stark, ii. p. 292.) 



I only identified one of these birds, but I believe that 

 they were common. I overlooked them till just before they 

 left in the autumn. 



73. Hirundo cucullata. (Stark, ii. p. 298.) 



Very common. I found one nest with a curved tunnel to 

 it. When the young were hatched, the parents broke a hole 

 in the bowl and added a second tunnel, which was straight. 

 I suppose that the parents found the curve awkward when 

 they had to feed the young so often. 



74. Petrochelidon spilodera. (Stark, ii. p. 304.) 



A colony of this Swallow occupied the underside of an 

 arch of a railway-bridge near Aliwal North. There must 

 have been at least eighty nests. 



75. Upupa africana, Bechst. (S. & L. p. 134.) 

 Fairly common.
