other species of this sub-family (as we have seen above in the 

 case of the Mouse-Lemurs), which are generically distinct from 

 Opokmur, 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.
