38 NAUM ANN'S THRUSH. 



In the first edition I introduced the figure and notice of a bird 

 tinder the above name. The figure is taken from Gould's plate of 

 Turdus fuscatus, which was at that time considered by Gould and 

 other naturalists as identical with the true T. Naumanyiii, figured in 

 Plate LXVIII of Naumann's "Naturgeschichte der Vogel Deutsch- 

 lands," and fully described at p, 288 of that work. 



The identity of the two species was not however admitted by many 

 naturalists, and in the continuation of Naumann's work by Professor 

 Blasius, they are described and figured as distinct. Dr. Sclater has 

 entertained the question in the "Ibis/' vol. iv., p. 319, admitting the 

 correctness of this division, and giving a figure of what he considers 

 the true T. Naumannii, from a skin belonging to Mr. Gould, which 

 was that of a bird shot at Shangai, in March, 1850. 



Mr. Gould was kind enough to lend me this skin, which is very 

 faithfully copied in the "Ibis." 



That Turdus Naumannii of Temminck is specifically distinct from 

 T. fuscatus, Pallas, is settled in the affirmative. But what are we to 

 say of some of those birds which are given in ornithological works as 

 the true T. Naumannii? 



M. Jaubert, in his "Richesses Ornithologiques," figures and describes 

 two birds as T. Naumannii. One of these is stated to be an adult 

 male, the other a young one. The former was shot by M. Lauzin, in 

 the Commune d'Allauch, in the month of December; the young one 

 by M. Bonifay, in September, 1845. Neither of these birds has the 

 slightest resemblance to the China specimen figured by Dr. Sclater in 

 the "Ibis." M. Jaubert writes with a full knowledge that "Cette 

 Grive voisine du Turdus fuscatus de Pallas." Peferring however to 

 Naumann^s original figures, it must be confessed that they differ as 

 much from M. Jaubert's as the latter do from Dr. Sclater's! 



Are the figures given by Naumann and that of Dr. Sclater identical? 

 This question admits, I think, of easy solution. Both Naumann's 

 figures, Plate LXVIII, are young birds, but in the history he gives a 

 most minute account of the adult male, and this description agrees 

 most accurately with the Shangai specimen, from which Dr. Sclater's 

 figure was taken. 



Dr. Schrenck, in his "Amur Peise," has also described a young 

 male T. Naumannii, and pointed out wherein it differs from T. fuscatus, 

 which is very common in that country. Assuming that his account of 

 T. Naumannii represents the real bird, it would seem to settle the 

 question of its specific difference, and that Jaubert's figures must be 

 referred to T. fuscatus, which bird will have to be admitted separately 

 into the European fauna.
