We believe that the bird from Kajo Kaji and the one 

 from Doleiba, which appears to be a juvenile, are identical 

 with C. petrophila Alex., a form which should be regarded 

 in our view as a subspecies of the West African C. rufo- 

 pileata. There is a good series of tliis form in the British 

 Museum from Northern ISIigeria and the Welle river, 

 collected by Alexander ; a single bird from Tingasi in the 

 Niam-Niani country, collected by Emin, and another labelled 

 Kibusi, Lango, north of Victoria Nile, obtained by 

 G. Blaine.

We cannot distinguish these birds from C. brachyptera 

 described by Sharpe, but subsequently (Cat. Birds, vii. p. 225) 

 identified with C. rufa (Fraser). The types of both species 

 are in the Museum, and we believe that they are quite 

 distinct. The two types of C. brachyptera are unsexed, but 

 the wings measure 48 and 42 mm. respectively, and they are 

 probably male and female. The Sudan birds measure, (^50, 

 ? 44 mm. This species is distinguished by its small size, 

 the head and back brown without any rufous, a slight wash 

 of rufous on the wings, and by the dull ashy (not white) 

 tips to the tail-feathers. It extends to southern Abyssinia 

 and south to Gaboon and Portuguese East Africa, and there 

 are probably several races, but the Sudanese biids appear 

 to be indistinguishable from the West African typical race. 

 The winter birds show distinct but not very heavy stripes on 

 the back, the summer birds are quite plain. 



The type of Cisticola hypoxantha Hartl.iub (P. Z. S. 1880, 

 p. 624 : Magungo, Nile Province of Uganda Protectorate), 

 now at Tring, has been examined by us, and is obviously 

 identical with the form of C. brachyptera occurring in the 

 Sudan. It is a young bird with the characteristic bright
