(after Oct. 23rd), 1851. Type (by monotypy) : Hirundo leucosternus Gould. 
This species is of very different coloration from the species of Hirundo, 
Hypurolepis, etc., and is characterised by its very small bill, the long forked 
tail with the outer feathers not attenuate, and comparatively heavy feet ; 
the tarsus being stout and long for a small Swallow, showing scarcely any 
scutellations, while the toes are short, the middle toe scarcely exceeding the 
hind-toe, the inner and outer subequal and shorter ; the claws long.
