after a heavy rain, doubtless following the swarms of winged ants and termites. 

 The months of specimens killed were crammed with these insects. When we 

 climbed Mount Iraya, June 12, its summit was covered with clouds, and large 

 flocks of swifts were feeding above the summit and at 200 to 300 feet lower. 



Cuculus canorus Linn. 



A female was taken June 2. Irides, clay color with inner dark ring; eyelids, 

 yellow; legs, nails and corners of mouth, yellow; middle toe nail dusky; bill, 

 black above, dark-green below. Length, 11.5 inches. 



Centropus carpenteri Mearns. 



This species is nearly identical with G. mi/ndorensis. I find no constant 

 difference in color and the difference in size is slight and variable. It is remark- 

 able that two species, so nearly related have such widely separated habitats.
