 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, 

 under coverts the same ; the median breast-feathers nearly 

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



Wing 2*3 inches, tail 2 - 12, bill from nostril 036, 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, Blyth, J. A. S. B. 1858, p. 270 ("Andamans "). 

 Geocichla albogularis, Blyth, apud nos, Ibis, 1874, p. 138 ("Andamans"). 



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

 the advantage of seeing examples of the Nicobar Geocichla, 

 named G. albogidaris 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 (I. 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
