72 Mr. R. B. Sliarpe on the 



tlie species in Borneo, as 1 have no doubt that the young bird 

 recorded by Count Salvadori from Sarawak was merely ii.pal- 

 lidus, Walden, a species which Count Salvadori did not recog- 

 nize in 1874. I have compared Mr. Whitehead's skin with 

 Javan specimens and find that they cannot be separated. 



[This Serpent-Eagle replaces the small Spilornis pallidas 

 in the higher regions of Kina Balu. 1 did not meet with it 

 below 3000 feet, and even at these altitudes it was scarce. 

 The crop of the specimen shot was full of lizards and snakes, 

 and I noticed it frequently beating along the dried-up beds of 

 rivers, where it would easily obtain the various rock-lizards 

 on which it preys.]

 [This species is more frequently met with in the jungle 



than in the open country. 1 do not remember observing it 

 above 1000 feet on Kina Balu, but my specimens were de- 

 stroyed by insects.]
