APPENDIX I 343 



In Pulu Atas I have also seen a solitary individual of" a 

 larger species of Heron, which, in the distance, appears to be 

 pure white ; this individual was well known to the natives of 

 the atoll. 



Pelecaniformes. 

 Suborder Fregati. 



(7) Fregata aquila, Linn. 

 Native name, Burung itam. ' 



Does not breed in the main atoll, but nests in large 

 numbers in Keeling Island. The nest is a slight collection of 

 twigs, stolen from the nesting Gannets, and placed on the flat 

 tops of the Pemphis bushes. The nests are crowded together 

 in thousands ; one egg only is laid, which is pure white and its 

 surface is shining ; eggs were abundant in June. The bird is 

 so tame in Keeling that it has to be driven from the egg, and 

 those birds that are sitting in the hot sun, with their wings 

 half spread, may easily be approached and lifted from the 

 ground. 



(8) Fregata ariel, Gould. 



This species is more common than the last. Its habits are 

 similar, and it nests freely with the larger species. It is also 

 called BuTung itam by the natives. 



Suborder Sul^. 



(9) Sula sula, Linn. 

 Native name, Burung hehek. 



I have never seen this bird in the main atoll, and its 

 numbers are somewhat limited in Keeling Island. It lays one 

 or two dirty white eggs on the bare ground, at the top of the 

 western sand-beaches. 



(10) Sula Abbotti, Ridgw. 

 Native name, Burung gangsa. 



Is not common in Keeling, and, so far as I have observed,
