tl.e feet pale brown, with a f.iiiil linpe of rufous above; ilie anterior 

 moiistflchial bristles dull vliiie, :ni(l iIjp posterior portion of tlie same 

 tuft blackish ; and the ears are nearly naked posteriorly, having only a 

 slight downy tuft near their buse, and a scanty border of minute hairs 

 near the margin, while anteriorly (or within) this border is more de- 

 veloped on the outer side, and there are some long hairs growing from 

 the inner corner ; the form of the ears is a rounded oval, with a very 

 slight indication of a terminal angle at the extremity of the outer edge, 

 the margin being sliglitly fringed with whitish ; the nose is completely 

 hairy ; there is a more decided tinge of rufous on the forehead, and on 

 the sides of the neck toward tlie fore-limbs ; and the ear lirs the 

 usual internal conch, or involucrum, observable in other members of 

 this genus. The skull measures 1| inch in total length, and I ineh across 

 at the zygomtE near the hind edge of the orbits ; from front of bony 

 palate to inferior margin of occipital foramen not quite § inch ; and tha 

 vertical height, with lower jaw in situ, ^ inch. I cannot do better than 

 apply to this species the name of Lagomys ffodgsonii. It is obviously 

 distinct from all the others. 



It may be remarked, that a fossil species of Lagomys, from the Osse- 

 ous Brecchia of the Island of Corsica, is noticed by Baron Cuvier, who 

 describes and figures the skull in his " Ossemens Fossiles," torn, vi., page 

 59S, (6ih edition, and plate 175,) figs. 4, 5, and 6.
