I must postpone the description of the limb-bones for a future 

 opportunity, when limb-bones of recent species, it is hoped, may be 

 available for comparison. The characters of the teeth come in the 

 first line for a comparison with other Miocene squirrels. When the 

 lower incisor of the Oeningen fossil was laid bare, it revealed 

 a longitudinal striation of the enamel ; this peculiarity, by itself, at 

 once settles the question as to the affinities of the Oeningen squirrel. 

 In the 56'. sperm ophiUtiiis, Dap , from La Grive, I have described and 

 figured the same character of the lower incisors ; ^ so that the identity 

 of the La Grive species with Sc. Bredai is fairly established. 



The lower molars in the Oeningen specimen are unfortunately 

 much worn and ra. 3 is missing, so that I am unable to verify 

 two other characters which I have described in Sc. spermopJiilimis 

 and by which it agrees with some Oriental squirrels, viz., the great 

 elevation of the antero-internal cusp and the elongation of m. 3.
