61. CiiVNYRis KiRKi. (Eastern Amethyst Sun-bird.) 

 This little species is almost as plentiful as C. chalybea, and, 



like that species, the male seems to retain its plumage 

 throughout the year. The nest, usually suspended from a 

 twig, is made of much the same materials as those used by 

 the preceding species, but it is much more neat and com- 

 pact, with less spiders'-web. The eggs (17 X 12 mm.) are pale 

 greenish grey, clouded streakily with very pale olive, which 

 almost obscures the ground-colour. 



62. ZosTEROPs ANDERssoNi. (Audcrsson's White-eye.) 

 Common at all seasons, busily searching the trees for 



insects, either in pairs or in family parties of five or six. 



63. Chelidon urbica. (House-Martin.) 



Only observed by Mr. Ayres in October on the Rwerwe 

 river. In connection with this name it may be mentioned 

 that the Zulu '' r " is pronounced like the German '^ ch."' 



64. CoTiLE ciNCTA. (Collarcd Sand-Mariin.) 



This is the only Sand-Martin that I have succeeded in 

 identifying. It is fairly common, occurring in small flocks 

 in the neighbourhood of water. Like most of this family, it 

 arrives about the secoud week in September, leaving again 

 in the end of March or beginning of April. 



65. HiRUNDO RUSTiCA. (Europeau Swallow.) 



Fairly common. Although Andersson has recorded this 

 species as breeding in Damaraland, I am not yet aware that 

 it does so in this country. 



66. HiRUNDO DiMiDiATA. (Pcarly-brcasted Swallow.) 

 Plentiful, this being the only Swallow that remains with 



us the whole year round. 



67. HiRUNDo GRisEOPYGA. (Ashy-backcd Swallow.) 



Mr. Ayres met with this species on the Rwerwe river, but 

 says it was not common. 



68. HiRUNDO cucuLLATA. (Larger Stripe -breasted 

 Swallow.) 



This well-kuown species would appear to be somewhat
