Genus— AUSTRARTAMUS. 
Austrartamus Mathews, Austral Ay. Rec., Vol. I., 
pt. 5, p. 114, Dec. 24th, 1912. Type (by original 
designation) Artamus melanops Gould. 
The diagnostic features I cited read “ Differs from Artamus in its narrow 
and weaker bill, and weaker feet and much shorter wing ; from Campbellornis 
in its shorter broader bill and shorter tail.” This describes the structural 
features but does not signify the great difference between these forms. Thus 
this genus is the inland evolution from the ancestral form of “ Artamus ,” 
and is a sedentary form showing great variation geographically. 
Note. The types of all forms described are in my collection at Tring, unless otherwise stated.
