Miiscisaxicola rubricapilla Philippi and Landbeck, Archiv. natur- 

 gesch., 1865, 1, p. 90 ("Cordillera der Hacienda de la Puerta, Provinz 

 Colchagua," Chile). 



The specimen which proves to be the type of Lafresnaye's Musci- 

 saxicola albilora was listed by Verreaux in his Catalogue of the Lafres- 

 naye Collection as Muscisaxicola rufivertex, and by Sclater (Cat. 

 birds Brit, mus., 1888, 14, p. 58) doubtfully as a synonym of Musci- 

 saxicola jtminensis Tackzanowski. A comparison with M. juninensis 

 and M. rubricapilla shows bej'ond doubt its identity with the latter, 

 which it antedates by ten years. The two subspecies should now 

 stand as : — 



Muscisaxicola albilora albilora Lafr. 



Muscisaxicola albilora jtminensis Tackz.

Type. — Regulus ovinicolor Vieillot. 



The generic name Tachuris Lafresna3e (1836), ha-\ang priority over 

 Cyanotis Swainson (1837), must replace it. The two forms contained 

 in this genus are : — 



Tachuris rubrigastra rubrigastra (Vieillot). 



Tachuris rubrigastra alticola (Berlepsch and Stolzmann).

In some manner Lafresnaye's name Tyrannula cincracea, long ago 

 became applied to the South American black phoebe, and that bird
