the markings are always most dense towards the broad end, where a more or less ill- 

 defined zone or irregular and partial cap are not uncommon. In length they vary from 

 0'68 to 0'75 inch, and in breadth from 0"5 to 0'56 inch. The average of a large number 

 of measurements is 0*72 by 0"52 inch." 



Mr. W. T. Blanford found the nests near Chanda, " under rocky ledges on the banks 

 of rivers," and he was not quite sure that they were not deserted nests of Hirundo ruji- 

 ceps (i. e. S. smithii). He once found eggs in what appeared to be a deserted nest of 

 Sir undo flu vico la . 



The descriptions are taken from specimens in the British Museum, the figures being 

 drawn from birds obtained by Mr. Wyatt near the Jumna at Etawah. He found it 

 nesting on the walls of the fort at Agra, a part of which is represented in the sketch.
