BIRDS FROM SIAM AND THE MALAY PENINSULA 35 



form probably escapes observation and is more numerous than the 

 scattered records indicate. 



The form has a wide range, occurring from central and southeastern 

 China to India, Siam, Indo-Cliina, south through the Malay Peninsula 

 to the Greater Sunda Islands, Pliilippines, and Celebes. Other forms 

 occur on islands to the southward. 



Family CICONIIDAE: Storks, Jabirus 



IBIS LEUCOCEPHALUS (Pennant) 



Tantalus leucocephalus Pennant, Indian zoology, p. 11, pi. 10, 1769 (Ceylon). 



One adult female, Nakon Sritamarat, September 27, 1926. 



Robinson^* reports storks common in Bandon and records tliree speci- 

 mens from Langkawi; GaLrdner^^ gives it for the Petchaburi District; 

 Robinson and Kloss^^ for Nong Kok, Ghirbi; Herbert^'' says his col- 

 lector reported it as nesting at Ban Yang in July but did not succeed 

 in obtaining eggs. 



The species ranges from Ceylon through India to Burma, south- 

 west China, Indo-China, and Siam. In Peninsular Siam it is said 

 not to range south of Langkawi. I have seen no records from north- 

 ern Siam.
