1288 A GLIMPSE OF THE POST-TERTIARY AVIFAUNA OF QUEENSLAND, 
noticeable in the Tantalidie, and become in the Australian 
representative of the Ciconidse so pronounced as to give a dis- 
tinctive facies to its articulating end in its length, narrowness, 
and salient edges. This we recognise at once in the fossil under 
view; and noting further its strong resemblance to the Jabiru’s 
tibia in the massiveness, direction, and sculpture of the bridge 
traversing the intercondylar space, we cannot but admit con- 
generic affinity between the two. But the fossil tibia, which 
shows no signs of immaturity, is in the mean two-ninths less in 
its dimensions than the recent bone, indicating a bird but little 
iQore than half the bulk of the jabiru of the present day. There 
are, moreover, structural differences perceptible in it ; the rotular 
channel is shallower ; there is considerably less intercondylar 
space behind the posterior edge of the bridge, the canal under the 
bridge is relatively very much wider, the ectocondylar tubercle is 
not prominent, and the double flexure inwards and forwards 
apparent in the living jabiru between the shaft and the articular 
end is scarcely appreciable. It will perhaps be granted that there 
is on the whole sufficient justification for the claim to specific 
rank preferred on behalf of the bird whose bone the fossil was. 
Proximal end of an ulna . — Asa postscript to the above maybe 
noted a later acquisition conflrming it, so far as the size of the 
bird is concerned ; unfortunately its worn condition unfits it for 
flescription.

l^roximal half of a right scapula . — In the majority of l)ij'ds within 
the writer’s range of observation, the glenoid fossa rests upon an 
expansion to a greater or less' extent of the head of the scapula. 
From this the .shaft generally narrows rapidly for a space, then 
expands and flattens to form the blade. In a few instances among 
Raptores, and again among Pigeons, the palmar edge of the 
glenoid process is slightly recurved and the surface beneath it 
rendered thereby a little concave; in the Bustard (^Chorions') this 
is carried to a much greater extent. Here the lip is distinctly 
reflected, and the side of the process at its distal half is converted
