Specimens examined. — Six from Pulo Kundur and two from near 

 the mouth of the Kateman River, eastern Sumatra. 



Remarlxs. — The six skins from Pulo Kundur show no important 

 variations. All have the gra}^ head markings well developed and the 

 thigh patches large and conspicuous. In one female (No. 122911) the 

 back is lighter than usual and the legs are browner, probably the result 

 of bleaching. In the two from the Kateman River the thigh patches 

 are somewhat reduced.
