Lasiopyga preussi insularis (Thomas). 



Cercopithecus preussi insularis Thos., Ann. Mag. Nat. Hist., 8th 

 Ser., V, 1910, p. 191. 



Type locality. N. Bantabiri, Island of Fernando Po, West Africa. 



Genl. Char. Like L. preussi but darker. 



Color. Hairs on upper parts blackish slate at their bases for over 

 half their length, then ringed with dull buffy and tipped broadly with 

 black. Tail at root chestnut. Young female. No dimensions given. 



It can hardy be considered that the subspecific distinctness of a 

 Fernando Po race, has as yet been well established, the material, one 

 immature female, being hardly sufficient. An examination of additional 

 adult examples is desirable. 



Lasiopyga THOMASi (Mat.schie).
