sounds soniethino- like " ke kelirk/' and while uttering it 



they point iheir wings downwards at a slant and slightly 



elevate their tails. They also utter a note like that of a kid, 



as described of other niemhers of the genus. I was not ahle 



to find out whether both sexes have the same call-notes. Two 



out of the three specimens obtained by driving the scrub 



with goats were similar to the first two collected on this trip, 



but the third was quite different, and I must say I was 



l)U7.zled for some time, as T did not think it possible that two 



distinct species would be found in the same limited area. On 



sexing them, however, 1 found that the two were femnles, 



and the third differently coloured one an adult male, and I 



came to the conclusion that they must all be of the same 



species. 



Mr. Austin Roberts and I have carefully compared the 



types of C. fjf. nooDiei collected in the Waterberg District 



w ith those from Blaauwberg, a single specimen from Dakn, 



Bechuanaland Protectorate, and another from C. Wilde's 



collection with no locality indicated, and have come to the 



conclusion that they are all C. g. sunderaUi, the juvenile 



plumage being that described as C. g. noomei. The specimen 



from Daka is an adult, and was correctly labelled as C. g. 



sundevallL Since my return from Blaauwberg, Mr. Carinus, 



of the Native Affairs Department at that place, has kindly 



sent me four more specimens, and the Transvaal Museum 



collection is now represented b)' fourteen skins, clearly 



showing the different phases of plumage. I am still doiii)t- 



ful, however, as to whether they retain the same })lumage all 



the year round, as in one of the females I collected, which is 



obviously fully adult, the feathers of tlu^ throat are moulting 



from grey to buftish. The youngest s})ecimen in the seiit's is 



the immature s[)ecimen mentioned as one of the fir>t I 



collected at Blaauwl)erg ; it is mueh wai'mer buftish coloured 



below, yellowish grey on the uj)per surface like the ^Vaterberg 



specimens, and has the lower niJindible and gape yellow. In 



th<( adults the back and top of he:id are ashy grey, the 



throat, breast, and sides slightly ])aler ashy grey, only the 



niifldle of the lower breast and abtlomen huffish white, and
