It may be convenient for future comparers of the hind-limb bones of Dinorms to 

 have, in a tabular form, the principal dimensions of the femiir, tibia, and metatarsus of 

 the species now named. In this table are given references to the figures of the type 

 specimens aff'ording the dimensions ; and there are added remarks and dimensions of 

 bones obtained by Dr. Haast, F.R.S., from the swamp of Glenmark, and which are 

 referable to the above species of Dinorms.
