BLACK-THROATED THRUSH. 279 



T. naumannl ; and finally, Naumanu abandoned bis belief 

 and adopted tbe name T.atrigularis, wbicli bas a clear priority 

 — tbougb wbo sbould be considered its donor is not so 

 certain. Tbe German ornithologists generally ascribe tbe 

 name to Natterer, wbo is said, and probably witb trutb, to 

 have been tbe first to recognize and point out tbe characters 

 of tbe species ; but all seem to admit that be never pub- 

 lished any notice of it, and thus his claim to acknowledg- 

 ment must yield to that of Temminck, as previously quoted. 



Tbe foregoing figure and tbe following description of 

 this species are taken from a Siberian specimen in tbe 

 Museum of tbe University of Cambridge : — Above, almost 

 uniform olive-grey, rather darker on the bead, and having 

 a slightly rufous tinge on tbe quills, the shafts of which are 

 liver-brown. Lores and ear-coverts blackish ; above the 

 eye a short dirty-white streak. Chin dirty white ; throat 

 and chest dull brownish-black, tbe feathers edged and tipped 

 with dirty white ; breast and belly dull white witb ill-defined 

 dusky streaks ; lower tail-coverts white varied by irregular 

 and suffused streaks of reddish-brown ; flanks dull hair- 

 brown ; axillaries and lower wing-coverts dull reddish- 

 orange ; quills beneath brownish-grey. Whole length about 

 nine inches and a half : wing from tbe carpal joint five inches 

 and three-eighths. Mr. Jerdon states that tbe bill is yellow, 

 dusky at the tip ; the orbits yellow ; the legs boney-yellow- 

 brown ; the irides dark brown. 



Col. Tytler (Ibis, 1869, p. 124) gives descriptions of five 

 specimens — two adult and two young males, and one adult 

 female, whence it would appear that the old males have an 

 almost black gorget, while this part in the younger males 

 and the female is more or less varied by dull white, and in 

 the last the markings l)eneath are more clearly defined.* 



* Mr. Bond possesses a specimen of Turdus sibiricus, sold to him some years 

 ago by a dealer who said it was shot in Surrey. He considered it a dark variety 

 of the Redwing, and such it was thought to be until its true character was re- 

 cognized by Mr. Blyth. This is another of those eastern species which frequently 

 find their way to western Europe, and there seems no reason why the man's story 

 should not be true. The absence of all details of the bird's capture in this 

 country may, however, excuse any further mention of it here.
