S. 83 ff. spricht Darwin über die Artverbchiedenheit von 

 M. mentalis d'Orb. und M. macloviana Gray foJgender- 

 massen : „2) Mnscisaxicola macloviaa G. R. Gray. Sylvia 

 macloviana Garn. Voy. de Coqu. Zool. p. 663. — Curruca 

 macloviana Less. 



J brought Lome only one specimen of this bird ; it 

 came from East Falkland Island, wlience also those di- 

 scribed by Messrs. Lesson and Garnot were procured. 

 Mr. Gould considercd it a distinct species , bnt having 

 carefully compared it with M. mentalis, J can see not de 

 smallest differcnce in any point, excepting that it is so- 

 mewhat larger in all its dimensions. The length of the 

 whole body is . 6, of an inch greater, of wing when foide 

 d. .45, of tarsus.2, greater than in the foregoing species. 

 J can scarcely hesitate in thinking it a large-sized local 

 variety, from some favourable condition in the Falkland 

 Islands to its grovy^th."
