Genus— DULCIORNIS. 
Bulciornis Mathews, Austral Av. Kec., Vol. I., 
pt. 5, p. 112, Dee. 24, 1912. Type (by 
original designation) ... ... ... ... Megalurus alisteri Mathews. 
I diagnosed this genus thus : “ Differs from Megalurus in its shorter bill 
and weaker feet, while the wings and tail are also shorter: from Poodytes 
in its stronger stouter bill and stronger feet with longer wings and compara- 
tively shorter tail ; the wing has the first primary comparatively longer than 
in Poodytes.” 
Large “ Warblers ” with short, stout bills, rounded wings, long wedge- 
shaped tails and strong legs and stout feet. 
The bill is short and stout, with little basal expansion and sides com- 
pressed, lower mandible heavy and as stout as upper ; culmen-ridge rounded, 
tip little decurved and obsolete notching only seen ; the nasal groove is about 
one-third the length of the culmen and the nasal apertures are linear and oper- 
culate, the frontal feathering approaching on to the nasal groove but not 
obscuring the nostrils ; the interramal space feathered, rami little diverging, 
about half length of mandible, gonys ascending ; there are two rictal bristles. 
The wing is rounded, the first primary short, about half the length of the 
third, which is little longer than the second and eighth, the intervening ones 
subequal and longest, the secondaries equal to the tenth primary, which is 
not much shorter than the longest. 
The tail is long and wedge-shaped, the outer feathers about half the length 
of the middle ones, feathers pointed, outer webs very narrow, the tail-coverts, 
both upper and under, short. 
The legs short and stout, the anterior portion of the tarsus showing five 
scutes, sometimes obscurely, posterior bilaminate. The middle toe is longest, 
without claw, equalling the inner with claw, which is subequal with the outer, 
claws short ; hind-toe stout, the claw long but only equal to the inner toe 
with claw.
