Pterosauria
2. Same specimen seen from the proximal end, so as to display
the distal end, twisted at right angles with the radial
crest. The pneumatic foramen is on the anterior and
radial side.
3. Proximal end of left humerus showing the radial crest
perfect. =J=._a_.6. 25.
4. Articular surface of same specimen showing the termination
of the radial crest.
5. Posterior aspect of proximal end of right humerus. The
pneumatic foramen is on the posterior and ulnar side.
6. Proximal articular surface of left humerus. =J=._a_.6, no. 2.
7. Distal end of right humerus. =J=._a_.6, no. 29.
8. Distal articulation of left humerus. =J=._a_.6, no. 45.
9. Distal end of same specimen.
10. Distal end of left humerus. =J=._a_.6.20.
11. Distal end of right humerus. =J=._a_.6.46.
12. Distal end of left humerus. =J=._a_.6.34.
13. Distal end of left humerus from a specimen lent by
J. B. Lee, Esq.
14. Distal end of left humerus. =J=._a_.6.35.

Carpal Bones.
Fig. 1. Distal surface of right proximal carpal bone, p. 48.
2. Same specimen seen from outer end, showing the large
unarticular surface, above is a part of the distal
articulation. =J=._b_.1, no. 1. (figured upside down).
3. Proximal articular surface of right proximal carpal bone.
=J=._b_.1, no. 7. The right upper part is for the radius,
the left lower part for the ulna.
4. View of same specimen (upside down) from the ulnar side.
5. View of same specimen from the radial side.
------------------
6. Portion of distal articular surface of a right distal carpal
bone. =J=._b_.3, no. 23, 4/5 nat. size, p. 50.
7. Front radial side of right distal carpal. =J=._b_.3.24.
8. Back ulnar side of the same specimen.
9. Proximal articular surface of the same distal carpal.
10. Distal articular surface of the same distal carpal.
11. View of the proximal articular surface of the same
distal carpal, seen from the inside.
12. Perfect element of left distal carpal bone showing the
distal carpal bone to be composite.
13. Distal surface of a right distal carpal of another genus.
=J=._b_.3, no. 20.
------------------
14. Lateral carpal or pisiform bone, seen from the inside, the
distal articular talon partly broken. =J=._b_.4, no. 2.
15. Lateral carpal seen from the outside. =J=._b_.4.9.
16. Same bone showing the distal articulation, p. 51.
17. Lateral carpal bone of a different genus, seen from the
inside.
