Genus— HALL ORNIS. 
Hallornis Mathews, Austral Av. Rec., Vol. I., 
pt. 5., p. 113. December 24, 1912. Type 
(by original designation) Malurus cyanotus= 
M alums leuconotus Gould. 
“ Differs from Malurus in its weaker bill and feet, its longer, more wedge- 
shaped tail and in lacking the erectile ear-coverts.” 
The bill is short and stout, comparatively shorter and weaker than that of 
the preceding, slight basal expansion, culmen more arched and more strongly 
keeled ; there are no nasal bristles and the rictal bristles are few and obscure 
and scarcely noticeable ; the other features much as in the former genus. 
The wing is short and rounded, the third to the seventh primaries sub- 
equal and longest, the second only a little shorter than the third and equalled 
by the tenth primary and the secondaries ; the first primary is short, a little 
less than half the length of the third. 
The tail is comparatively longer and more wedge-shaped. 
The legs and feet are similar, but weaker throughout.
