 By Arthur, Viscount Walden, P.Z.S./F.R.S. 



Alcippe collaris, n. sp. 



Throat, chin, lores, a broad supercilium extending to behind 

 the eye and down the side of the neck, white ; a broad line ex- 

 tending from the nostrils over the eye, then bordering the 

 white superciliary band above, and running down the side of 

 the neck, black ; cheeks and ear-coverts black ; across the 

 lower throat a broad ferruginous band or collar, separating 

 the white throat from the dingy olive-brown plumage of the 

 breast, flanks, and abdomen ; thigh-coverts and under tail- 

 coverts bright ferruginous ; forehead, crown of the head, 

 and nape ferruginous brown ; back, scapulars, and upper 

 tail-coverts olive-brown, with a ruddy tinge ; rectrices above 

 liver-brown ; quills brown, edged exteriorly with liver- 

 brown; shoulder-edge albescent dashed with ferruginous, 

 uuder coverts the same ; the median breast-feathers nearly 

 pure white ; bill black ; legs (in dried skin) yellowish-brown. 



V^ing 2-3 inches, tail 2-12, bill from nostril 0-36, tarsus 0'85. 



Described from a male example obtained by Surgeon-Major 

 F. Day at Sudya, Upper Assam, on the 12th of January, 

 1874. 



This species possesses an especial interest, as it is a repre- 

 sentative form of the Formosan Alcippe brunnea, Gould, an 

 aberrant member of the genus. 



Geocichla andamanensis^ n. sp. 



Geocichla innotata, Blytli, J. A. S. B. 1858, p. 270 ('^Andamans "). 

 Geocichla alhogtilaris, felyth, njmd nos, Ibis, 1874, p. 138 ("Andamans"). 



When writing on Andaman birds (L c.) I had not had 

 the advantage of seeing examples of the Nicobar Geocichla^ 

 named G. alhogxdaris by Mr. Blyth. Lately a considerable 

 series has come under my observation ; and a comparison 

 made between them and Andaman examples makes it clear 

 that they belong to a totally distinct species. Having already 

 shown (Z. c.) that the Andaman species differs from the Malayan 

 G. innotata^ it remains without a title ; and therefore for the 

 Andaman bird I propose the name given above. 



Eurycercus cinerascens, n. sp. 

 Chin, throat, breast, cheeks, and under carpal coverts almost
