90 MR. E. R. ALSTON ON THE GENUS ANOMALURUS. [Feb. 16, 
Through the kindness of Professor Flower and Dr. Giinther, I 
have been enabled to examine specimens of two species of Anomal- 
ure preserved in spirits in the Museum of the Royal College of 
Surgeons and the British Museum, and have hence been led to 
reconsider the question of the nature and affinities of the animal. 
I have to acknowledge the kind help of my friend Mr. Garrod in 
the examination and comparison of the very remarkable viscera, 
which do not appear to have been previously described. 
STRUCTURE. 
External characters.—With regard to these little can be added to 
Mr. Waterhouse’s excellent original description. On examining 
specimens in spirits, however, one peculiarity is observed which is 
less striking in dry skins. This is the arrangement and form of the 
tubercles on the naked soles of the feet. The fore feet have a series 
of five tubercles at the base of the toes (in A. pelii the second inner 
tubercle is nearly divided in two); behind these there is a small 
round isolated one in the centre of the sole, and on each side a

larger callosity. In the hind feet there is a series of six at the base 
of the toes, with a small central, one long internal, and two external 
tubercles. This remarkable arrangement, which is very similar in 
all the species, is well shown in the figure. The number of scales 
in the caudal series varies slightly in different individuals. As 
already noticed, the cartilage, or chondrified fascia, which supports 
the flying expansion or patagium, is attached to the olecranon instead
