Family SYLVIIDAE. 

 Eremomela flaviventris (Burchell) . 

 The name of the South African warbler now known as Eremomela 

 flaviventris is invalidated because it was originally described as Sylvia 

 flaviventris Burchell (Trav. South Air., I, 1822, p. 335, note; Asbestos 

 Mountains, 14 miles north of the Orange River, Griqualand West, South 

 Africa), and because this is preoccupied by Sylvia flaviventris Vieillot 

 (Nouv. Diet. d'Hist. Nat., XI, 1817, p. 241; Paris, France), which is 

 now relegated to the synonymy of Phylloscopus trochilus (Linnaeus). It 

 has apparently no synonym, and we therefore rechristen it Eremomela 

 griseoflava perimacha, nom. nov. It is here treated as a subspecies of 

 Eremomela griseoflava Heuglin (Journ. f. Ornith., 1862, p. 40), since this 

 name now becomes the earliest one among all the forms of this species 

 and must, therefore, from a nomenclatural standpoint, become the typical 

 race. These subspecies will now stand as follows: 



Eremomela griseoflava griseoflava Heuglin. 



Eremomela griseoflava abdominalis Reichenow. 



Eremomela griseoflava sharpei Reichenow. 



Eremomela griseoflava perimacha Oberholser. 



Eremomela griseoflava erlangeri Reichenow. 



Eremomela griseoflava flavicrissalis Sharpe. 



Family TURDOIDIDAE. 

 Crateropus griseus (Gmelin). 

 The Turdus griseus of Gmelin (Syst. Nat., I, ii, 1769, p. 824; Coromandel 

 Coast, India), which is now in use for an Indian babbling thrush in the 

 combination Crateropus griseus, is preoccupied by Turdus griseus Bod- 

 daert (Tabl. Planch. Enlum. d'Hist. Nat., 1783, p. 39; Cayenne), which 

 is now called Microrhopias grisea (Boddaert). Dr. C. W. Richmond has 

 already called attention (Proc. U. S. Nat. Mus., LIU, August 16, 1917, 

 p. 627) to the fact that the generic name Crateropus Swainson must be 

 superseded by Turdoides Cretzschmar. In view of this and of the fact 

 that Crateropus griseus, lacking synonyms, is in need of a new name, we 

 propose that it be known as Turdoides polioplocamus Oberholser, nom. 

 nov. 



Family TIMAUIDAE. 



Arrenga cyanea (Horsfield). 

 This Javan species, the Turdus cyaneus of Horsfield (Trans. Linn. 

 Soc. Lond., XIII, May, 1821, p. 149; Java), can no longer be called by its 

 present specific name, because this is ineligible for further use on account 

 of the earlier Turdus cyaneus of Mxiller (Vollstand. Natursyst. Suppl., 

 1776, p. 145; Cape of Good Hope, southern Africa), applied to some other 

 bird. The next and only other available specific designation appears to be 

 Pitta glaucina Temminck (Nouv. Rec. Planch. Col. d'Ois., II, livr. 33, 

 1823, pi. 194; Java); and the name of this bird, should, therefore, hence- 

 forth be Arrenga glaucina (Temminck).
