1 A serpent-eagle also occurs in the Pagi Islands, West Sumatra. I now 
think that Kloss and I were wrong in linking this race to S. elgini. 
* The evidence for the occurrence of this species in Borneo is very slight, 
but as it occurs in Celebes we have retained it in the Bornean list for the 
present.
