2S British Birds, with their Nests and Eggs. 



Family- TURDID^. Subfamily- TURDINAi. 



The Rock Thrush. 



Monticola saxaiilis, LiNN. 

 A DMITTED, because one specimen was shot at Tlierfield, Herts., in 1843. 



So far as I can see, there is no more reason for admitting these birds to 

 our list, than for excluding the following : — 



Favi ily— TURD ID ^. Sicbfam ily— TURDIN.E . 



The American Robin. 



Turdus migratorius, LiNN. 



OBTAINED at Dover ; but excluded, on the ground that it may have 

 escaped from captivity. In these days of aviculture, even the rarest and 

 least suspected birds mav have reached our shores in this manner. 



Family— TURDIDyE. Subfamily— TURDIN^. 



The Siberian Ground Thrush. 



T^irdtis sibiricus, Pall. 



SO]ME writers admit, and others exclude this species ; one example only 

 having been obtained (on the authorit}- of a dealer) between Guildford 

 and Godalming, in the winter of 1860-61. 



In other branches of Zoology, we should not necessarily regard a species 

 as British, on the score of one or two examples having been obtained on our 

 shores : the fact of their occurrence would be recorded, and possibl}^ an 

 illustration published, but subsequent works would not be considered incomplete 

 which did not describe them as British.
