A brightly marked form resembling Ph. I. aztecus. Colours 

 sharply and strongly contrasted. Ground-colour rich ferru-

 limbs and feet white instead of brown. 



Philander laniger jivaro, subsp. n. 



Most nearly allied to Ph. I. ornatus, Tseh., the Peruvian 

 representative of the group ; but, while that is more or less 

 rufous in general tone (a strongly marked specimen is nearest 

 to " amber-brown/' Ridgway), the present form is a dark

 "cinnamon-brown" (Ridgway, 1912). Under surface ave- 

 raging rather darker than in ornatus, the axillary hairs not 

 lighter than those of the belly. Inguinal region dull white. 

 Outer side of hips hoary grey. Tail with the difference in
