long as the diameter of the very large orbits. 

 17. Otogale. Skull ovate. Face rather elongate, as long as the 

 diameter of the moderate sized-orbits. 



Or the last section, C, may be divided thus : —

 termaxillary not thickened in front; upper cutting-teeth close 

 to the canines. 



15. Otolicnus. Skull globular, thin. Upper cutting-teeth small.

 of the orbit. 



17. Otogale. Skull ovate, solid. Face as long as the diameter 

 of the orbit. 



More detailed characters of the new genera are given in the ' Cata- 

 logue of Monkeys and Lemurs in the British Museum,' and there- 

 fore are not repeated here. 



Tribe 1. Lepilemurina. 



1. Lepilemur, Gray, Cat. Monkeys & Lemurs, 1870, p. 134. 



The skull of this genus is figured in Pollen's ' Fauna Madagascar.' 

 t.7.f.3. M. Adolphe Milne-Edwards says that there are cutting-teeth 

 in the upper jaw when the animal is young ; but I do not know on 

 what authority. They must be very small, as the intermaxillary bone 

 is so slender. 



Lepilemur pallidicauda. 



Fur pale grey ; chin, inner side of limbs and underside of body 

 whitish. Shoulders and outer side of the fore legs brownish- washed, 

 the tail uniform pale brownish or reddish white-grey, like the back 

 at the upperside of the base, which extends the furthest down the 

 tail in the female.
