324 MR. R. B. SIIARPE ON THE BIRDS OF LABUAN. [Apr. 1, 



Suborder Pandiones. 



8. Pandion leucocephalus, Gould. 



Pandion leucocephalus, Sharpe, Cat. J3. i. p. 451. 



Pandion haliaetus (L.), Salvad. t. c. p. 7. 



An adult specimen (No. 44) sent by Mr. Treacher, who gives the 

 native name as "Alang piak " — the same, it will be observed, as that 

 applied to Haliaetus leucogaster. The species was procured at 

 Sarawak by Doria and Beccari, but has not been previously met 

 with by the English collectors in N.W. Borneo. 



Suborder Striges. 

 Family Strigid^e. 



9. Ketupa javanensis, Less. 



Ketupa javanensis, Salvad. t. c. p. 20; Sharpe, Cat. B. ii. p. 8. 



Two fine specimens, one dated December 18/6, were sent by 

 Governor Ussher. Mr. Treacher sends three adult birds, with the 

 native name " Bugang." 



10. Phodilus badius (Horsf.). 



Phodilus badius, Motl. & Dillw. t. c. p. 8 ; Salvad. t. c. p. 22. 



One specimen was sent by Mr. Low. It has already been recorded 

 as a Labuan bird by Messrs. Motley and Dillwyn ; indeed Mr. 

 Motley speaks of it as being rarely seen, but not uncommon in the 

 island. This appears somewhat strange when we consider the dili- 

 gent efforts of Governor Ussher and Mr. Treacher to exhaust the 

 avifauna of Labuan, and yet neither of them ever procured a speci- 

 men. It may, therefore, be migratory, and only plentiful at certain 

 seasons of the year. Native name " Burong hantoo " {Motley). 



11. Ninox scutulata (Raffles). 



Ninox scutulata, Sharpe, Cat. B. ii. p. 156. 



Ninox boi-neensis, Bp., Salvad. t. c, p. 18; Sharpe, P. Z. S. 18/5, 

 p. 99. 



Of this bird I have now examined a large series sent by Mr. Low, 

 Governor Ussher, and Mr. Treacher, and I have very little to add to 

 the remarks which I published in the ' Catalogue of Birds.' The 

 characters which I there supposed might distinguish the Labuan 

 bird as a race seem to me to be insufficient to warrant this conclu- 

 sion. The uniform first primary appears to be a matter of age ; and 

 the number of caudal bars probably depends upon the same cause. 

 In Mr. Treacher's series the majority of the specimens have five 

 tail-bars, but one has only four. Native name " Pungok" {Treacher). 



Two specimens from Labuan were in Mr. Low's collection ; one 

 of them a dark-coloured bird with four bands on the tail, and ob- 

 solete traces of fulvous bars on the inner web of the first primary. 

 This belongs to the usual dark Labuan form of this Ninox ; and it 

 breeds in the island, Mr. Low having obtained two eggs with this 

 identical specimen. The latter are very small for the size of the
