I only know this bird by the above specific description and 
figure, which induce me to suppose that it must be distinct from 
any of the other species of Collocalia, in which genus it was first 
placed by Prince Bonaparte. 
The figure in the ‘ Voyage de l’Astrolabe’ represents the bird 
as fuliginous, with the head, upper part of back, wings, and tail 
shining metallic black. The habits of this bird and the forma- 
tion of its nest are unknown, which is also the case with the 
next three species.
