The nests are infested by bugs (Cimicidae); in one 
single nest I counted 555 bugs, the very small larvae 
included. The nest contained a nearly hatched egg, and 
was therefore occupied, a fact, which seems next to incre- 
dible. The nests were made of moss and other vegetable 
matter, fixed to the wall with the well-known slimy excre- 
tion from the buccal glands. 
The 3 No. 3721 was caught sitting on a nest, the 
Nos. 3722, 3723, 3724 and 3725 are nestlings.

Iris, bill and feet black. 
Wing 127 mm. 
The rump of this specimen is the same dark colour 
as the rest of the upper parts. 
This is probably an eastern race of Collocalia inno- 
minata, but we have not sufficient material of it to decide 
the point.
