"In its large size, deeply emarginate tail, and lack of tarsal feathering 

 CoUocalia origenis agrees with Collocalia whiteheadi, but is readily dis- 

 tinguishable by the dark colors, particularly on the upper parts which are 

 even more blackish than in CoJlocalia fuciphaga from the Philippines." 



Oberholser gives measurements of two males as follows : Wing, 129, 

 138; tail, 53, 60; exposed culmen, 6, 5.5; tarsus, 13, 14. Two females: 

 Wing, 134, 130; tail, 51, 54; exposed culmen, 5.5; tarsus, 12.5, 14. 



"This new species was discovered by Doctor Mearns during his recent 

 trip to the Island of Mindanao, the four adults obtained having been 

 brought by natives who had found them in a cave on Mount Apo."
