This fine species was of frequent occurrence, but seen usually 

 singly or in pairs. Its white head and rump contrasting with its 

 dark wings, made it rather a striking object in the air.

o? Le Gud. 



Head, entire upper parts and tail dark slaty gray, with a green- 

 ish tinge; rump, buff; throat, whitish buff; flanks, dark buff; 

 under parts, buffy white; wings, same color as back; bill, black; 

 total length, skin, about 3.40; wing, 2. 10; tail, 1. 10; bill, .50 inch. 



This species, which is apparently new, is nearest to S. 

 rufescens, from South Africa, but instead of being dark buff 

 beneath, as is that species, it is almost white, washed with buff. 

 The type was the only individual obtained.

This little species apparently has quite an extensive distribu- 

 tion, as the two localities where we obtained examples were about 

 one hundred miles apart.
