1863.] DR. J. E. GRAY ON THE SPECIES OF LEMUROIDS. IJl 



side over the axilla and the groin ; tail very long, cylindrical, nearly 

 half as long again as the body and head. 



Hub. Fernando Po {Capt. Burton, 11. M. Consul). 



Hind feet 2" 6'". Skull, length 2", breadth 1" 4'". 



Skull: orbits prominent and produced on the sides, voider than 

 the zygomatic arch. 



This species, which has the teeth exactly like the other Otogales, 

 by the shortness of its head and the large size of the eyes and orbit 

 of the skull forms a passage to the Galagoids*. 



II. The head short, subglobose ; face short, tapering ; eyes very large. 



The skull is short, broad, depressed. The face very short, coni- 

 cal, tapering. Orbits very large, the zygomatic arches slender. 



* The hind legs much longer than the fore ; fingers free, tvell 

 developed ; tail elongate, hairy. 



f Feet short, broad ; ears small, hairy, hidden ; teeth 30, viz. 

 grinders ^^, cutting teeth j. Microrhynchina. 



7. MiCRORHYNCHUS, Jourdan, 1834. 



Avahis, I. Geoff. 1835. 



Indris, A. Smith, 1834. 



Semnocebus, Lesson, 1840. 



Tail elongate, cylindrical, hairy. Ears hidden under the fur. 

 Nostrils separated by a narrow septum. Hind foot short and broad. 

 Claws elongate, convex, acute ; claw of front toe elongate, cylindrical. 



MiCRORHYNCHUS LANIGER. B.M. 



Lemur laniger, Gmelin. 

 L. lanatus, Schreb. 

 Avahis laniger, I. Geoff. 



Brown, varied ; rump, spot over groin, and beneath whitish, with 

 a narrow white lunate band on the forehead. 

 Hab. Madagascar. 

 Length of foot about 2\ inches. 



ft Feet short and broad, about two-thirds the length of the shank 

 or shin; teeth 36, grinders g^^, cutting teeth ■^, the upper 

 ones placed one before the other. Galagonina. 



8. Hapalemur, I. Geoff. 

 Hapalolemur, Giebel, 1859. 



* Since this paper has been in print, I have procured from among some frag- 

 ments of skins belonging to M. Du Chaillu a very imperfect skin, in a bad state, 

 of a Lemur which appears to belong to this species ; but it has a small white tip 

 to the tail (probably accidental). It is marked " Otolicnus apicalis," so that this 

 white-tipped variety is probably the animal noticed under that name in the 

 Appendix to M. Du Chaillu's ' Travels,' p. 471.
