BIRDS FROM SIAM AND THE MALAY PENINSULA 33 



This bird has been recorded in southwestern and Peninsular Siam 

 from Ratburi, Petchaburi, Pakchan, Koh Lak, Junkseylon (Puket), 

 and Koh Pennan. Robinson and Kloss ^* say of its occurrence in the 

 Peninsula: "Probably partially naigrating and commonest in winter"; 

 Gyldenstolpe ^^ reports it generally distributed throughout Siam. 



The form has a wide range, occurring from northeastern China 

 south to Indo-Cliina, Burma, India, Ceylon, Siam, the Malay Penin- 

 sula, Moluccas, and New Britain. The species has a still wider 

 range and has been split up into a good many forms of more or less 

 doubtful validity. 



NANNOCNUS CINNAMOMEUS (Gmelin) 



Ardea cinnamomea Gmelin, Systema naturae, vol. 1, pt. 2, 643, 1789 (China). 



Two adult males and two immature females, Bangkok, March 13 

 and April 7, 1926, and June 27 and October 27, 1924; one male (not 

 fully adult), Sichol, Bandon, May 28, 1930. 



Dr. W. L. Abbott took one adult male and one adult female, near 

 base of Kao Nom Phi, Trang, March 9, 1897, and one immature 

 female, Trang, January 22, 1897. 



Dr. Abbott gives the soft parts as follows: Iris yellow; feet greenish; 

 bill greenish yellow, brownish above and in a narrow line along 

 commissure. 



This species has been recorded from Pakchan, Patani, Junkseylon 

 (Puket), Ratburi, Petchaburi, and Tasan, Chumpon, and Peninsular 

 Siam;^® Deignan ^^ reports it resident at Chiengmai, but more abun- 

 dant during the rains; Herbert ^^ reports finding one nest with three 

 eggs on June 25 near Bangkok, and a second nest with three eggs was 

 found by his collector at Tachin on August 15. It is probably a com- 

 mon resident through Siam in suitable localities. 



The species has a wide range, occurring from Manchuria south 

 through China to Burma, India, Siam, Indo-China, the Pliilippincs, 

 and Celebes.
