Linnaeus' name tridactylus I'd'ers undoiiliteJIy to the Scandinavian bird, as he 

 gives as the "habitat": " Hab. in Svecia ad Alpes Lapponicas, Dalekarlicas 

 frequeus." Dr. Sharpe, in the Ilund-Ust, Vol. II p. 216, accepts Brehni's name 

 Si-'pti'iitrionalis for the Norwegian bird, inserting the following footnote : 

 " Apparently a distinct race, fide Reichenow in litt.," thus evidently erroneously 

 applying Linnaeus' name triclacti/lus to the Central European bird. Brehm's name 

 scptcnfrionalis was founded on a Norwegian specimen, and is therefore clearly a 

 synonym of tridacti/lus. 



The Alpine form differs from typical trid(ict>/lus in its much more heavily 

 barred sides and flanks, in the white dorsal stripe being variegated with black 

 markings, the head of the female being less marked with white, and the siiles of 

 the head being blacker. These differences are already mentioned by Hargitt, 

 Cat. B. XVIII p. 276, though he did not venture to separate this form. We 

 accept Brehm's name, as he clearly stated the differences between the Scandinavian 

 and Alpine forms ; while Lesson's description of P. eiiropaeus, although referring 

 principally to the Alpine birds, applies equally well to the whole genus Picoides, 

 and is therefore quite inadequate. AVe have a number of Brehm's original 

 specimens before us, collected in the years 1830-35. 



The differences of 7^. crissoleueus are well stated in the Catalogue of Birds, 

 Vol. XVIII and elsewhere ; but it seems that in some collections specimens of 

 alpiims are treated as young crissoleiicus, owing to their being vaguely labelled 

 " Siberia." 



P. albidior is confined to Kamtschatka, and has the lateral rectrices unbarred, 

 ■white with a black base, while even the whitest specimens of crissoleucits always 

 show traces of bars.

In spite of what Dr. Sharpe says in the Moiwyraph of Tardidae by Mr. 

 Seebohm, the Asiatic Missel-thrush is a very well distinguished subspecies, which 

 is consjiicuous for its much larger size, and must stand as above. (Cf. Hartert, 

 Kat. Voyelsamml. Seiiclienberg. Mas. ji. 7, note 18.)
