which is the female of tliat species. It is curious to find the 

 South-African Ceblepyris casia placed as an inhabitant of North- 

 Eastern Africa ; but the author assures us that there can be no 

 doubt as to the identity of the specimen in Prince Paul of Wiirt- 

 temberg's collection, on the authority of which the bird is in- 

 cluded in the avifauna of North-eastern Africa. The Musci- 

 capa chocolatina of E-iippell is now referred to the genus Brady- 

 ornis. Concerning this bird the latter author made the curious 

 mistake of twice including it in his ' Systematische Uebersicht^ 

 (pp. 37 and 49), under the respective names of Muscicapa cho- 

 colatina and Curruca chocolatina ! It is easy to imagine how the 

 mistake came about ; but it nevertheless proved a stumbling- 

 block to ornithologists, who ought therefore to be not a little 

 grateful for the elucidation of the error, especially as the iden- 

 tity of the species has been proved by an examination of the 

 types. It is interesting to see that M. semipartita, Riipp., is 

 referred to Cassinia ; but I am inclined to doubt its being strictly 

 congeneric. 



On the authority of a specimen obtained by Speke in Unia- 

 muezi, Terpsiphone mutata is included in the present work. 

 Thisj to say the least, is extraordniary ; for although the coasts 

 of Zanzibar and Mozambique exhibit certain Malagash affinities, 

 I cannot at this moment recall another instance of a truly Mala- 

 gash species occurring so far north as the above-mentioned 

 locality. Dr. von Heuglin separates the North-eastern Elmi- 

 nia as distinct from the West-African E. longicauda, under the 

 name of E. longicauda minor, which name he adopts in preference 

 to his previously proposed name of E. alexins. With Tele- 

 phonus erythropterus he includes the Algerian "Tschagra," which, 

 however, may be a distinct species, peculiar to Algeria ; but it 

 will be curious, if its specific distinctness be proved beyond a 

 doubt, to find an isolated form of the truly African genus Tele- 

 phonus resident within the limits of the Palsearctic region. I 

 must demur to the insertion of T. trivirgatus in the present 

 work, on the authority of a specimen in the Berlin Museum ; 

 for I believe it to be strictly a southern form. Again, on 

 the same authority, I must question T. longirostris being an 

 Abyssinian bird. I very much doubt if this species, which I
