accurate. notion of its principal parts. His report runs as fol- 
lows :— 
“Skull, neck, and both hands wanting. Of the vertebral 
column, the greater part of the vertebre of the trunk and the 
whole of those of the tail are completely preserved. The former 
are of moderate length, and uncovered ; the tail, which measures 
upwards of 6 inches, consists of about twenty vertebre of an elon- 
gate narrow form, the dimensions of which slowly but constantly 
diminish, so that the last of them is the smallest. Of the an- 
terior limbs, the humerus and fore-arm are present on both sides; 
they are strong bones, pretty nearly of equal length, and the 
fore-arm consists of radius and ulna. At the anterior extremity 
of each fore-arm there is a broad, short bone, but this is in- 
jured. 
“Of the pelvis only the right half is preserved; it is but 
small, and is comparable not with the pelvis of a bird, but rather 
with that of a Pterodactyle. On the left side, the whole hinder 
extremity is preserved; on the right, only the thigh and shank. 
The former is a powerful and not very long bone; the latter is 
somewhat longer and thinner, and is simple; at least, a se- 
paration into tibia and fibula is not perceptible. The tarsus 
consists only of a single powerful bone, which is shorter than 
the shank-bone with which it is in contact ; its lower extremity 
is considerably widened, and bears three articular processes, to 
which the three toes are attached. The latter are of moderate 
length, and armed with strong hooked claws. 
“ Feathers occur both on the anterior limbs and on the tail ; 
they have, however, left only their impressions, but these show 
sharply defined outlines, and upon a passing glance they present 
a deceptive resemblance to birds’ feathers. From the above- 
mentioned short broad bone, which lies close to the extremity of 
each fore-arm, there issues a radiate fan of feathers, by which there- 
fore, as a structure of this kind radiates from each fore-arm, two 
feather-wings are produced, having their external outline curved 
like a bow. ‘The individual feathers are characterized by their 
fine shafts, on each side of which the delicate striation of the 
vanes is seen. The largest of these feathers considerably exceed 
in size that described by Von Meyer. 
“Similar feathers are attached to the tail, but with this di- 
stinction, that they do not attain the length of the wing-feathers, 
and, which is of more importance, they do not radiate like the 
latter from a central point, but spring from both sides of the 
tail throughout its whole length, and start from it at a small 
angle. ‘The tail-feathers form a group of an elongated leaf-like 
or oval shape, of which the narrow end issues from the be-
