Hiri/s of Gazaland. 103 



on December 18tli at Mucliukwana, eighteen miles east of 

 Chibabava. They were present in considerable numbers^ 

 hawking about and settling on the trees^ and were apparently 

 on their way inland from the coast, as I found them then 

 scattered throughout the couuti'y as far as Beira, where 

 numbers were to be seen perching on the telegraph-wires in 

 the neighbourhood of the town. On my return to Chirinda 

 on January 10th I found them there already, but they 

 disappeared again three weeks later. 



145. HiiiuNDo ALBiGULARis. Whitc-throated Swallow. 

 P. I noted several of these birds in December and 



January in the low veld, hawking about and settling on trees 

 and wires in company with Hirundo rustica. 



146. Hirundo dimidiata. Pearl-breasted Swallow. 



Rh. I seem to have only once noted this formerly 

 common Swallow during the past tw^elve months, namely, 

 on March 31st, at Umlangeni^s kraal on the upper Buzi, 

 where a number were hawking over some old Kafir lands. 

 The stomach of one in my collection contained flies and 

 small beetles. 



147. HiRUXDO ATROC.ERULEA. BluC SwalloW. 



Rh. This is a fairly common Swallow which has in the 

 past frequently visited us at Chirinda, remaining usually for 

 some wrecks at a time, but I seem last year to have seen 

 much less of it than of either H. griseopijga or cf PsaUdn- 

 procne orientalis. It was with us, however, during November, 

 in some numbers, and early in the previous month I had 

 noted it on the Chipetzana River ; while, during September, 

 I found it to be common right through Northern Melsetter, 

 particularly in the Nyahodi Valley and about the township 

 itself. 



A male, evidently breeding, shot on March 22nd, measured 

 8"5 inches ; the stomach contained flies only. 



This Swallow was previously supposed to be confined to 

 Natal.
