but this latter character is perhaps in some measure due to 
abrasion of its edges. On the palmar surface the eminences 
and ridges for muscular insertions are very much as in D. norce-hol- 
landice, the differences in themselves being scarcely of .specific value. 
Left coracoid. — coracoids of living Ratitie are so strongly 
diflerentiated from each other, as well as from those of the Carinatie 
generally, that there is but little difficulty in recognizing one of 
them in the fo.ssil state within generic limits. The present subject 
is clearly the coracoid of an emu, but having been broken away 
forcibly from the scapula below its line of confluence therewith, 
its clavicular process having been lost with the missing portion, 
and the articular part of its humeral process being also absent, 
it afllbrds in its remainder but scant guidance to its specific 
identity. Its proportions are not greatly different from those of 
I). nouB-hoUandice ; in the least width of the shaft, it is, however, 
one-tenth narrower, and consequently it has a slender appearance. 
In D. noi'ce-hollandice a canal passes through the inner edge of the 
shaft about the middle; no trace of this is to be found in the fossil, 
in which again the pneumatic foramen beneath the humeral process 
is larger, and is approached by a short but deep groove in the 
surface of the shaft. In the existing emu, so far as the writer has 
observed, there is also a foramen similarly placed, but quite 
minute and opening directly on the convex surface of the bone. 
On the small portioir remaining of the upper edge, appearances do 
not favour the idea that it supported the claA'icle which in. I).
