44 DUSKY TEBU8H. 



Dr. E-adde does not describe the old bird, which is unfortunate: he 

 remarks it has been done so often that it is unnecessary; but it is 

 quite evident he got into confusion with his skins. One thing seems 

 quite clear, that the young of T. Naumanni, T. fuscatus, and T. 

 ruficollis are very much alike. Radde says they are undistinguishable, 

 but Mr. Sclater says that in a long series this can be done easily 

 enough. 



It is quite probable that the above three forms intercross with each 

 other. Mr. Swinhoe is of this opinion as well as Radde. They con- 

 stitute, in fact, three races or permanent varieties, and as such must 

 be treated in scientific works as three species. 



From Salvadori, (''Fauna d'ltalia," p. 84,) I take the following: — 

 "This Thrush is one of the. rarest in Italy, and is also very rare 

 all over Europe. I have seen three specimens taken in Italy: one 

 is in the Museum of Turin, and was killed in the neighbourhood of 

 that city in the autumn of 1829; another was taken to the market 

 of Geneva, in the winter of 1862, and makes part of De Negri's 

 collection. I mentioned this bird in a note of my Catalogue of 

 the Birds of Sardinia, but in error I indicated it by the name of 

 T. Naumanni. A third I have seen in the collection of Count 

 Camozzi, of Bergamo, and it was captured in Bresciano, in November, 

 1844. Of this I possess a beautiful drawing, designed and coloured 

 by Professor de Filippi, who gave it to me. This last is a full- 

 grown adult, and is perfectly represented in Naumann's plate 359, 

 fig. 1. If I do not mistake. Professor de Filippi speaks of the cap- 

 ture of this individual in the Congress of the Italian Scientific 

 Association in Naples, and described it under the name of T. 

 Naumanni, but Bonaparte with reason thinks that it was in reality 

 T. fuscatus. This Thrush belongs to eastern and northern Asia, 

 and is also found in Giappone. I consider the species quite distinct 

 from T. Naumanni, which I do not believe has ever occurred in 

 Italy. I retain for this species the name of T. fuscatus, Pallas, 

 though it does not appear to me doubtful that to it_, and not to T. 

 jyallens, as Bonaparte will have it, ought to be referred T. ohscurus, 

 Gmelin. 



N.B. — Pisso announces, among the birds of passage in Nice, a 

 Turdus harharicus , but nobody knows what it is." 



Mr. Swinhoe has most kindly placed in my hands a series of skins 

 of this bird, from which I make the following descriptions: — 



Adult male, marked "Ningpo, March, 1872," is a beautifully 

 plumaged bird, as will be seen by reference to my figure. Head 

 and upper back' dark olive with black centres to the feathers. Back,
