iu had condition; bat we think that two birds collected by Griffith near Pushut in 

 Afghanistan are referable to C. diluta, and a skin from Madras [Jerdon] may also belong 

 to it, as well as a specimen collected by Mr. Pratt near Ichang in Central China. Now 

 that attention has been drawn to this pale form of Common Sand-Martin, we shall 

 doubtless receive more information respecting it, as a larger series than we possess in 

 England is necessary for the correct determination of its range.
