Genus— MICRARTAMUS. 
Micrartamus Mathews, Austral Av. Rec., Vol. I., 
pt. 5, p. 114, Dec. 24th, 1912. Type (by 
original designation) . . Artamus minor Vieillot. 
This very different form of Wood-Swallow was diagnosed thus : “ Differs 
from Pseudartamus in its still weaker bill, though broad, and weaker feet 
and shorter wings and tail.” 
The bill is broadly triangular, sharp tipped, swollen basally with the 
breadth at base almost equal to length, the rictal bristles very small, but 
the bill is a regular development of the Artamoid style on the exactly opposite 
direction to that of Campbellornis. The birds are small and more compact 
for aerial work, the legs being very delicate, and the claws long and curved 
for clutching prey, not perching.
