plane, and are expanded with a large pneumatic foramen (a) on the external 
surface, overhanging which is a triangular articular surface (0). ` The coracoids 
have not been found, but must have been stout triangular bones 2 inches in 
length and 1} inches wide at the sternal attachment. The scapula also is 
missing. 
VERTEBR Z. 
The following vertebre have been preserved :— The 2nd, 3rd, 5th, 6th, 7th, 
8th, 10th, llth, 13th, and 14th cervical; 2nd, 4th, 5th, and 6th rib- 
bearing or dorsal; the last having no hypapophysis may be termed the first of 
two pre-sacrals, the second of which is wanting. . The total number of vertebræ 
. seems to have been :—

The 3rd, 4th, and 5th ribs of the right side; the 6th and 7th of the left, 
and also the 7th sternal rib of the same side, have been preserved. The first 
six ribs have well pronounced uncinate processes (a) with a broad attachment 
one inch in length, that on the 6th rib (a’), being bent backwards so as to be 
almost parallel with the bone, and having a blunt expanded tip. The ribs 
are much compressed, their margins having wavy irregular outlines. They 
are broad in the middle and taper off towards each extremity, when viewed 
laterally. The last two ribs articulated with sacral segments, the total 
number having probably been nine. The number of sternal ribs was seven,

The humerus has already been described, so far as it differs from the bone 
attributed to Cnemiornis by Professor Owen, and the femur, tibia, and tarso- 
metatarsal have been figured in Pl XIV.A for convenience of reference by 
collectors. They agree so perfectly with Professor Owen's description as to 
require no further notice, except to point out that the external articular 
process of the metatarse, instead of being obliquely reflexed, as in the goose, 
swan, and other swimming birds, is straight, as in true cursorial birds, 
indicating that the habit of the bird was rather to walk on land than swim in 
- water. 
'The metacarpal (figs. 6, 7) is made up of the first and second digits, which 
are completely fused at both extremities, leaving a narrow interspace (a) for less 
than half the length of the bone. It resembles closely the corresponding bone
