NO. 5 NEW MAMMALS FROM PANAMA — GOLDMAN "J 



Remarks. — This species, the only known nocturnal monkey of 

 Panama, closely resembles A. griseimembra of the Santa Marta 

 region of Colombia in external appearance, the principal difference 

 being a more general buffy suffusion of the body and limbs. The 

 skull, however, differs in many important respects and the larger 

 molariform teeth of the Panama animal would alone serve as a dis- 

 tinguishing character. 



Specimens examined. — Total number, lo, from localities as fol- 

 lows: 



Canal Zone: Gatun (type locality), 4. 



Panama : Cana, 3 ; Boca de Cupe, 3.
