convenience in tliem for more than one pair of birds to incubate. 
They consist of a much thicker and heavier mass of material than 
the nest of G. subfurcatus ; but where two are built in contact, the 
wall of separation is thin, though we suspect it will be always found 
intact and completely separated. During the night, C. affinis is 
equally vigilant with its Malayan representative. The latter would 
appear to be the common house Swift of the Malayan peninsula, 
taking the place of G. affinis of India ; while G. vittatus would seem 
to be exclusively a mountain species, which is common at Pinang, 
and which has been obtained by Captain Hutton from the Tyne 
range of mountains near Simla, and G. leuconyx may be the repre- 
sentative of the last on the mountains of S. India." — (Blyth.)
