1863.] VR. J. E. GRAY ON THK SPECIES OF LEMUROIDS. ] 49 



and below reJdish grey ; tail one-half longer than the body and head^ 

 darker at the hinder half. • 



Skull, length 1" 5"', width lOi'". Length of hind foot I" 8'". 



Had. West Africa : Gaboon. 



There are several specimens of this animal in the Museum Col- 

 lection. The skin of the adult measures about .5 inches long, from 

 the tip of the nose to the base of the tail ; the tail is 7^ inches long ; 

 the hind I'oot and shin are about 1 inch 8 lines long. There are 

 some smaller specimens in spirits, which appear to he 3'ounger, 

 which have the hind foot only 1 inch and from 4 to 6 lines long. 



I am induced to suppose tnat Mr. Murray's Galago murinus from 

 Old Calabar is the young of this species, as the hind foot is figured 

 about Xiy inch long. 



The skull without a lower jaw, which in the Museum Catalogue 

 of Bones is put under Microcebus myoxinus (p. 33), evidently belongs- 

 to this species. 



**** Tail cylindrical, elongate; ears small, partly hidden.

Rat de Madagascar, Buffon, Suppl. iii. p. 147, t. 20? 



Hab. Madagascar. 



Buffon's figure of Le Rat de Madagascar, which is the type of 

 Lemur pusillus, represents the animal as having a short hind foot, 

 and in that particular better represents my Cheirogaleus minor than 

 any animal th.it M. L Geoffroy would place with the Galagina, 

 or M. Dahlbom with the Macrotarsce. I have never seen a Lemur 

 with small ears and a long foot ; so that I suppose a true Microcebus 

 has not occurred to me ; and I doubt much if Buffon's figure repre- 

 sents the genus.
