Similar to L. pileatus, but rather smaller, and the cap of a 

 lighter brown. 



Hub. Brazil, Guiana, and E. Peru. 



It is difficult to keep the Guianan examples of this species 

 separate from L. pileatus, but the head is rather paler in colour. 

 The skin upon which L. peruvianus was based is small in dimen- 

 sions, but the tint of the brown head is exactly that of Guianan 

 specimens, and intermediate between that of L. pileatus and 

 L. amaurocephalus.
