MR. ST. GEORGE MIVART ON THE LEMURlDyE. [DeC. 12, 



together, and not at all hidden by the auditory bullae. The ptery- 

 goid fossa also is much elongated from behind forwards, but very 

 narrow from side to side, the true pterygoids extending back much 

 more nearly to the same distance, as do the ectopterygoid plates, 

 than is the case in the smaller species {M. minor). Compare fig. 2 

 with the figure of the latter species in P. Z. S. 1864, p. 615. 



Fis. 2. 



Chcirogahus furcifer. Scale twice iiat. size. 



The extent of the praemaxilla cannot be ascertained, the suture 

 being completely obliterated. As regards the skull, then, C. furcifer 

 agrees altogether with C. milii, and even carries still further those 

 characters (length of first upper premolar and smallness of last lower 

 molar) in which the latter species differs from M. jnisillus and M. 

 myoxinus.
