Three were taken on Xomuka, Tonga Islands, 2 December. 

 Only one of these, an adult female, has the sex indicated without 

 question. The remaining two are immature birds that differ from the 

 adult in having the chestnut of the forehead faintly indicated anteriorly 

 and ob.solete behind. In addition the blue-black spots on the under 

 tail coverts are lacking, and in one bird there are faintly indicated pale 

 margins on the feathers of the back. This species is known from the 

 Tonga Islands but has not been reported from Xonmka previously. 

 The large, broadened bill, characteristic of the gentLs Hypurolepis 

 Gould, reaches its maximum de^■elopment in this species, and appears 

 remarkably strong and heavy for a swallow.
