other species of this sub-family (as we have seen above in the 
case of the Mouse-Lemurs), which are generically distinct from 
Opolemur, share this peculiarity. 
The two species included in this genus are intermediate be- 
tween the Mouse-Lemurs and the Dwarf-Lemurs, and are 
really more nearly related to the former than to the latter. The 
skull is flat and depressed as in Chirogale, and the brain-case 
small and almost vertical behind. ‘The posterior foramina in 
the palate are small. In respect to their dentition, the cusps 
of the upper molars are blunter and shorter than in the Mouse- 
Lemurs, but less so than among the Dwarf-Lemurs; the hind 
inner cusps of the anterior and median molars are large, and 
the ridge from the inner cusp is less intimately joined to the 
two outer cusps than in the Dwarf-Lemurs.
