MUTANDA ORNITHOLOGICA. 



IX. 

 BY HARRY C. OBERHOLSER. 



Further notes 1 on untenable names of birds are furnished 

 below. These refer to species in the families Corvidae, Mota- 

 cillidae, Sylviidae, Turdoididae, and Timaliidae. 



Family CORVIDAE. 

 Dendrocitta sinensis (Latham). 

 The name Dendrocitta sinensis for a Chinese jay must now be changed, 

 since its basis, Corvus sinensis Latham (Index Ornith., I, 1790, p. 161; 

 Macao Island, China), is found to be preoccupied by Corvus sinensis 

 Gmelin (Syst. Nat., I, i, 1788, p. 372; China) for another and unidentified 

 species. Since no other name is available for Dendrocitta sinensis, we 

 propose to call it Dendrocitta celadina, nom. nov. 



Family MOTACILLIDAE. 



Motacilla longicauda Riippell. 



The name Motacilla longicauda Riippell (Neue Wirb. Faun. Abyss., 

 Vog., 1835, p. 84, pi. XIX, fig. 2; Province of Simen, Abyssinia), for a well 

 known African wagtail, is untenable on account of the previous Motacilla 

 longicauda Gmelin (Syst. Nat., I, ii, 1789, p. 954, China), a synonym of 

 Sutoria sutoria (Forster). Its only synonym, Motacilla longicaudata 

 Grant and Reid (Ibis, ser. 8, I, No. IV, October, 1901, p. 630; nom. emend, 

 pro Motacilla longicauda Riippell), is preoccupied by Motacilla longicau- 

 data Hermann (Observ. Zool., 1804, p. 210; no locality). A new specific 

 designation is therefore necessary for Motacilla longicauda Riippell, and 

 we provide it in Motacilla rhadinura, nom. nov.
