and are black in the dried skin. S. mystacea, on the other 

 hand, reminds one greatly of S. suhalpina in general appear- 

 ance, though it has the underparts much paler ; but the white 

 mystacal line is very clearly defined in both these species. 



The measurements of the specimens examined are given 

 on p. 361. 



The last of the above-cited specimens is stated to have 

 come from N. Africa, but no authority is given, and it is 

 stated to have been purchased, so I give the locality with a 

 query, this being the only record of S. mystacea having been 

 obtained in N. Africa. 



These two species differ also in the coloration of the soft 

 parts. According to von Heuglin, S. momus has the legs 

 yellowish red, the bare skin round the eye red, and the iris 

 " turn helvola turn lateritia." On the labels of Canon Tris- 

 tram^s specimens of this species the iris is marked as being 

 lemon-yellow, but he does not give any further particulars. 

 In S. mystacea the beak is (according to Menetries) brown, the 

 lower mandible yellow on the basal half, the iris clear chest- 

 nut-red, and the bare skin round the eye yellow ; the legs 

 isabelline, and the claws black. Blanford does not state the 

 colour of the iris, but figures it as being reddish brown ; the 

 legs are, he says, brown. 



In accordance with what has been stated above, the 

 synonymy of these two Warblers will now stand as follows, 

 viz. : —
