144 DR. J, K. GRAY ON THE SPECIES OF LEMUROIDS. [April 21, 



Streak up the nose between the orbits, the cheeks, and the underside 

 whitish ; front of the orbits on the sides of the nose brown ; tail 

 rather browner, slender, rather longer than the head and body ; ears 

 rather large, rounded at the end, pale, covered with short scattered 

 hairs on the outside. 



Hab. Madagascar ; from Zoological Society. 



Miller's figures very well represent this animal, but the tail is 

 more bushy and browner than our specimens ; the feet are of the 

 proper size and form. The skull of the adult male has a rather 

 longer nose than those of the typical Galago ; and the orbits are very 

 large, but scarcely so large as some of the species of that genus. It 

 is 1" 2|"' long, and 9 J lines broad. The two front upper cutting 

 teeth are large and bifid, the inner ones small and cylindrical. The 

 upper canines are erect ; the lower ones are decumbent. The first 

 and second upper false grinders are slightly conical and compressed. 



Lepilemttr murinus. 



2. Lepilemur myoxinus. 



Microcebus myoxinus, Peters, Mossamb. Saugeth. i. 14, t. 4. 



Hind feet short, two-thirds of tibia. 



Hab. Eastern Madagascar. 



The figure of Dr. Peters agrees pretty well with our specimen of 

 L. murinus ; but the whole colour of the fur is rather darker, and the 

 ears are larger. The figure of the skull also agrees well with that 

 of L. murinus. This is not a Microcebus as now restricted ; the feet 

 are too short and broad for that genus. 



Skull, length 1" 4'" (according to the figure), breadth IQi'". 



It is very like my Cheirogaleus smithii, but the ears are too large. 

 The ears are very apt to be unnaturally stretched in the stuffing, or 

 the converse and allowed to shrink in the drying. 



3. Lepilemur mustelinus, I. Geoff. Cat, Mamm. ; Archives 

 du Mus. t. 



Rufous ; throat white ; forehead and cheeks grey ; lower part of 

 body yellowish ; the tail, hands, and lower part of the legs yellowish 

 grey ; outer side of the last third of the tail brown ; tail two-thirds 

 the length of the body ; ears large, rounded, membranaceous, dark. 



Length of head and body 14", of tail 10". 



Hab. Madagascar, 1842. 



The description of this animal agrees in most particulars with 

 Lepilemur, but it is said to have no upper cutting teeth. May not 

 this be a peculiarity of the single specimen on which the species is 

 founded ?
