Remarks. — The type locality is "Philippines," the exact local- 

 ity no longer known. Known also from Borneo and Malay 

 Peninsula. The type specimen was collected by H. Cuming, 

 1836-1840, and is in the British Museum. Evidently this 

 species and Varanus grayi are rare or are confined to some 

 particular island. So far as I know, no specimen other than 

 the type has been collected in the Philippines.
