628 Dr. R. B. Sharpe on Birds 



S. zenkeri the colour of the latter parts is pale orange- 

 rufous, not verging on chestnut. It must be remembered 

 that the Efulen bird is a female, and a further series may 

 shew the two species to be identical ; but so far as we know 

 at present they seem to be separable.

The sexes appear to be alike in colouring, but younger 

 birds seem to be more distinctly mottled with black spots 

 underneath, and to have rufescent margins to the feathers of 

 the upper surface, as in a Sand-Martin (Riparia). Old 

 birds appear to be more uniform and to lack these light 

 margins. The female obtained on the 31st of January 

 shews many traces of immaturity, and a male killed on the 

 14th of March has also remains of rufous margins to the 

 feathers.
