![Through the kindness of Professor Flower and Dr. Gunther, 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 office 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 Fig. 1. a. Fore foot, b. Hind foot, of Anomalurus fraseri, natural size. 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 cliondrified fascia, which supports the flying expansion or patagium, is attached to the olecranon instead [4]](https://iiif.wellcomecollection.org/image/b22455346_0006.jp2/full/800%2C/0/default.jpg)
