characteristic of the nests of many species of Collocalia. The 
nest is 3 centimeters deep, outside; 6.5 centimeters in greatest 
diameter (parallel to the supporting surface) ; and 5 centimeters 
from back to front—that is, the diameter at right angles to the 
supporting surface. The side that was against the rock is 
somewhat flattened and wings of the glutinous substance, 
attached to the rock and extending 2 centimeters from each side 
of the nest, serve as additional support. Other nests from this 
cave are composed of fine plant stems fastened together and 
to the rock wall in the usual manner. 
In each of three sets of eggs collected one egg was slightly 
incubated and the other egg was noticeably more advanced in
