Genus— SETOSURA. 
Setosura Mathews, Austral Ay. Rec., 
Yol. II., pts. 2/3, p. 58, Oct. 23, 
1913. Type (by original designa- 
tion ) ... ... ... ... ... Ehipidura setosa melvillensis Mathews. 
My definition of this genus reads : “ Differs from Leucocirca Swainson in its 
broader, longer bill, though the wing is much shorter and the legs and feet are 
much weaker, the metatarsus especially being much shorter.” 
This genus has proportionately the longest bill with restricted development 
of the feet, indicating a different line of evolution from the preceding and 
succeeding genera. 
The bill is long and flattened, triangular, keeled with the tip strongly 
decurved, the rictal bristles are very long, profuse and strong ; nostrils open, 
hidden by bristles and approached by frontal feathering. 
The wing has the third, fourth, fifth and sixth primaries longest, the fourth 
and fifth generally exceeding the other two ; the second is less than the seventh 
but exceeds the eighth. 
The tail is long and rounded, the feathers still soft and broad. 
The legs are short and weak, the tarsus distinctly scutellated in front in 
some cases, obscurely in others.
