150 ON RHAMPHORHYNCHUS BUCKLANDI 
deposited in the Geological Museum in Oxford, have néither been 
figured nor described, though Goldfuss invented for them the name 
of Prterodactylus Buckland?. When in Oxford a short time ago, I 
had the opportunity (thanks to the kindness of our President, the 
Curator of the Museum) of examining these remains; and in the 
course of my somewhat hasty inspection, I noted, among fragments 
of less moment,— 
1. A right humerus (Pl. XXIV. [Plate ro] fig. 7), 34 inches long, 
and 14 inch in diameter at its proximal end, which terminates in- 
ternally in a rounded articular head, more than half broken away, 
but seemingly about 4th of an inch thick, and externally is prolonged 
into a thin but strong process with rounded edges, whose anterior or 
proximal margin is decidedly concave. The proximal end of the 
shaft is flattened; but it becomes rounder, concave anteriorly and 
convex posteriorly, towards its distal end. This last is about ths of 
an inch wide, and strongly bent forwards, its plane forming an angle 
of about 45° with that of the proximal end of the bone. [The right 
humerus of the original specimen of Démorphodon macronyx lies in 
nearly the same position as this, and may be advantageously compared 
with it.] 
2. A right coraco-scapular bone, similar to, but smaller than, that 
which will be described below,—the coracoid measuring only 24 inches. 
in length, and the scapula 24 inches from the suture, which is visible 
half an inch above the lower edge of the coracoid. 
3. A distal phalangeal bone of the fourth, or web-finger, 64 inches 
long. This bone is nearly ;%;ths of an inch thick at its proximal end, 
where it is somewhat flattened from side to side. In the middle it 
becomes rounded, and remains so, gradually tapering to its slender 
distal end, which is a little flattened from side to side, and rounded 
off at its extremity, which looks like a natural termination. The 
bone is straight for the proximal 4} inches of its length; it then 
becomes slightly curved, so as to be convex forwards, and concave 
backwards, in the rest of its length. 
4. A fragment of a proximal phalanx of the same finger, em- 
bracing probably more than its proximal half, three inches long. 
The shaft of this bone is ;4ths of an inch thick ; its head, including 
its anterior process, measures more than an inch antero-posteriorly 
and its articular cavity is rather more than § an inch in diameter. 
5. A middle (2nd?) phalanx, 7$ inches long, and } an inch wide 
at its proximal end. 
6. Another middle (3rd?) phalanx of about the same length, but 
more slender.
