uot yet fullgrown , the hiudniost molars presenting them- 

 selves just above the level of the gums. There are 4 

 molars in each jaw. It here must be remembered that 

 Sciurus prevostii and its allied species, all the other Asiatic 

 striped squirrels and with a few exceptions nearly all the 

 Asiatic squirrels always possess -^ molars. The upper and 

 lower incisors are provided with deep longitudinal grooves 

 — 5 to 7 on each tooth in the upper jaw , 4 to 6 on 

 each tooth in the lower jaw ! — The skull compared with 

 that part of other large squirrels , for instance Scmrus 

 bicolor from Sumatra, shows that it is of a more elongated

The preceding will clearly show , that I erroneously 

 described the Saleyer squirrel as belonging to the same 

 group as Gray's macrotis^ that my error was a consequence 

 of the insufficient description by the latter author and 

 finally that Gray's genus Rheithrosciurus is a very good one.
