NATURE NOTES 
the idea of its being able to leap like a kangaroo. It has been suggested that 
the Iguanodon made progression across the ground after the manner of the 
Frilled Lizard (Chlamyiiosaurtts), and a stuffed specimen of this little creature in 
the act of running, gives some weight to the idea. 
The Pterosaurs, or winged lizards, show a great elongation in one of the 
fingers of each hand, and upon this long finger a membrane was supported, 
somewhat like the wing-membrane of the bat. The hard casing of the bones of 
the Pterosaur was filled with air cavities, thus combining strength with lightne.ss. 
Some of the winged lizards had long tails, others short ; some had large teeth 
fixed in sockets and some were toothless. Pleranodon had sharp-edged, pointed 
jaws a yard long and wings measuring l8 feet from tip to tip. 
Fossil serpents are scarce, but a few have been found in the Tertiary 
formations, one (Pahiof>his tyfilueui) measuring twenty feet in length. 
A hearty vote of thanks was offered to Dr. Andrews for his able and interesting 
demonstration. Before leaving the Selbornians to their own devices Dr. Andrews 
very kindly offered to show them his latest important discovery, the skull and 
mandibles (now in the Central Hall) ol a huge extinct mammal, found by him a 
few months ago in the Upper Eocene of the Fayum. This new acquisition is 
named Arsindilheritivi zitteli.

E. P. — Leonardo’s MSS. are somewhat scattered and the drawings have not 
all, I believe, been published, even in Dr. Richter’s great monograph, but the

recently reviewed and which reproduces many of those sketches.
