150 Dr. C. W. Andrews on 
and shoulder-girdle there are present the imperfect right and 
left scapule and coracoids, together with a left humerus wanting 
the middle of the shaft. The right scapula (fig. 3, 2) is complete 
with the exception of the end of the blade. The articular 
end is borne on a well-defined neck ; the rugose surface for 
union with the coracoid is triangular in outline, while the 
glenoid surface is rather greater than half a circle, and is not 
concave, but flat, or even slightly convex; it was probably 
covered with cartilage in life. The precoracoid process and 
the blade of the scapula diverge at an angle a little greater 
than a right angle ; they are both flattened. The scapula is 
very like that of Parachelys figured by v. Meyer *. 
The coracoids (fig. 8, 3) are represented by the proximal 
portion of the right and the expanded distal part of the 
left. The articular end is crushed, but it can be seen that 
with that of the scapula it formed a nearly flat oval glenoid 
surface. The distal portion of the coracoid is much expanded, 
as in Glyptops, Chelys, and the Testudinide. 
The humerus (fig. 3, 7) is represented by the two ends of the 
bone of the left side ; its length cannot be determined. The 
head is massive and rounded, very similar to that seen in 
Testudo. ‘The ulnar crest, which is somewhat incomplete at its 
summit, is much smaller than in Testudo, rises less beyond the 
head, and is not deflected downwards. ‘he radial crest is much 
smaller and is deflected on to the surface of the bone beneath 
the head. Distally the ectepicondylar groove and foramen 
lie close to the radial border. The distal articulation is 
divided by a groove into two convexities (for the radius and 
ulna), as also happens in Glyptops according to Hay (‘ Fossil 
Turtles of North America, p. 51). In some respects this 
humerus approaches that of Plewrosternum, but has undergone 
considerably less modification in the direction of adaptation 
for swimming. 
One alzwm is preserved ; the contracted shaft is roughly 
trihedral in section; both ends are much expanded, the upper, 
which is somewhat imperfect, bearing a roughened surface 
for union with the carapace, while the lower, which is still 
larger, bears the usual facets for the pubis, ischium, and 
acetabulum. 
An imperfect pubis was found ; it is much crushed and its 
median process is broken off. At its lower end it terminates 
in a roughened oval facet, which was no doubt in contact 
with the corresponding facet on the xiphiplastral.
