crest is in most clucks in advance of the junction of the sub- 
tuberous ridge with the shaft ; in Dendroeygna eytoni it is very 
nearly opposite to that point ; in the fossil it is opposite ; there 
is, moreover, in D. eytoyii a rather peculiar feature with which the 
fossil is in close agi’eement — the pectoral process is bent slightly 
but sharply downwards from the head, rising from a definite line 
of junction between the two. There appears, therefore, sufficient 
reason to refer the bone to the genus Dendroeygna, but it cannot 
be identified with either of the species now living in Australia! 
From D. eytoni, to which it has the greater resemblance, its 
didei’ential characters are these ; — the articular head is relatively 
of much larger size, and is more hemispherical^ the radial tubercle 
lai'oer. On the inner surface the rido-e borderinsf the sub-tuberous 
fossa above runs at a nearly right angle from the shaft, and the 
fossa itself is con.siclei’ably broader. Finally, the whole shows a 
superiority in size greater than may fairly be allowed to an 
individual of D. eytnuK 
Right ulna. — Intermediate in length between the ulnas of D. 
eytoni and D. gouldi, it is stronger than the latter, which, though 
consiclei’ably shorter, is less attenuated in the shaft than in the 
former. This has the reduction of the olecranal and radial 
processes usual in the swimming birds, and, to a less extent, in 
the waders. In the form and structure of the )>roximal articular 
surface it has greater resemblance to D. eytoni than to D. gouldi, 
but the reverse is the case iu the distal end. It differs from both 
in having the margin of the ulnar cavity carried across the radial 
edge, forming an angular line of division between the radial cavity 
and the facet for the head of the radius ; the insertion of the 
metacarpal flexor more sti’ongly marked, and pierced with two 
minute foramina ; and the row of (juill tubercles sca)-cely appreci- 
able to the touch. The distal joint differs only in size from that 
of D. eytoni.
