Remarks. — The chief distinguishing mark of this subspecies is the 

 brown color of the metatarsal region of the foot in contrast with the 

 buff-colored toes. The differences pointed out by Mr. Thomas in 

 regard to the "naked portion" of the tail is simply due to the manner 

 in which the skin of the tail of the type is stretched. This animal 

 was first recorded on the Malay Peninsula by Mr. Robinson in 1905.^ 

 Although the Selangor specimen was the first to be recorded in the 

 literature, Dr. W. L. Abbott was the first person to take Ptilocercus 

 on the Asiatic Continent, his Johore specimen being collected July 5, 

 1901, about two and a half years before the Selangor animal was 

 secured. 



Specimens examined. — Two from the Malay Peninsula, one from 

 Pulo Pinie. The two Sumatran specimens. I merely saw in their 

 exhibition cases without critically examining them. See table below. 

 In addition to these a skeleton of a specimen collected at Deli 

 Sumatra is recorded by Jentink,^
