into a broad shallow groove for insertion of ligament, but this 
}<roove not beinsc sunk below the General surface of the bone has 
no definite boundaries. It has so in the fossil referred to this 
family, for here the ligament is inserted into two deep confiuent 
excavations at the base of the process. If the presence of the 
groove be permitted to guide us to the Otididee, its condition 
showing the attachment of very strong ligaments will, in view of 
the superior size and massiveness of the bone itself compared Avitli 
its homologue in Choriotis, tend to confirm the guidance. Though 
not gi’eatly (2i mm.) wider at the base of the glenoid proce.ss than 
the scapula of a large male Bustard, its thickness more than half 
as great again, is disproportionate, and shows, other things being 
equal, a much more powerful bird. Its general shape is that pre- 
sented in Choriotis ; it has the same peculiarity, an almost equal 
width from the glenoid process to the commencement of the blade. 
On the outer dorsal side the general resemblance to Choriotis is 
much greater than to any other scapula compared with it, liut 
there are notwithstanding differences forbidding ascription to that 
genus. The ventral margin between the insertions of the swpra- 
spinatus and serralus parvus anticus, is broadly convex, throwing 
the spinatus insertion to the upper edge of the outer surface of 
the bone, the serratus insertion to the inner edge of the ventral 
margin ; the glenoid process is shorter but of greater vertical 
e.xtent, and the acromial process is but slightly concave at its base, 
and is separated by a distinct notch from the dorsal end of the 
glenoid process. On the inner surface the bone is throughout 
l emarkably convex transversely and straight longitudinally ; there 
is no ridge or other tract for the insertion of the siob -scapular is. 
ljufortunately the articular process and the greater part of the 
acromial process have been removed by fiacture and abrasion. 
In the aljsence of a skeleton of any member of this family 
other than Choriotis., it is impossible for the writer to detei inine 
the genus to which it belongs. The task is left to those who have 
1 letter means of accomjtlishing it j if it have Vieen mad(! to appear 
probable that the Bu.stards were represented in the old avifauna of 
Queenslantl, some piogress will have been mafle.
