PALE THRUSH. 197 



between male and female and different ages of young 

 not known. — Temminck. 



Figured by Werner, in the "Atlas to the Manual," 

 under the name of Tardus naumannii, and by Gould, 

 "B. of E.." 



In the next number I shall figure and describe 

 T. cya?ieus, but I take this opportunity of noticing 

 several species, some of which have been included by 

 Schlegel and others in the European fauna, and I will 

 quote the remarks of Schlegel himself upon these birds 

 in his "Revue" of 1844, as the best authority for 

 omitting them from this work. The question of 

 determining with exactness the claims of admission into 

 the European lists of many of these stragglers is very 

 difficult, and I have already incurred the rebuke of 

 the reviewer of my work in the "Ibis" on this point. 

 Sins of omission are, however, equally great with those 

 of commission, and I must content myself with the 

 exercise of the best judgment I can give of the evi- 

 dence on both sides, and perhaps by this means I shall 

 at least avoid the error of being too confident upon a 

 confessedly difficult question in ornithology. 



Tardus barbaricus, Gmelin. — Frequents according to 

 Risso, the environs of Nice. I cannot give any account 

 of this doubtful species, and therefore pass it in silence. 



Turdus rufus, Brisson. — Said by Schinz to have been 

 observed in England, but as he has not indicated the 

 source from whence he has derived this information, 

 I have not adopted this species among those observed 

 in Europe. 



Turdus sibiricus, Pallas. — Introduced into Temminck's 



"Manual" among the birds of Europe, from one indi- 

 vol. i. 2 E
