Pitta cyanea Blyth, Journ. Asiat. Soc. Bengal, vol. 12, p. 1008, 1843 (Arrakan). 



Two males, one adult, and one immature female, Khun Tan, 

 August 24-30, 1930. Dr. Smith also took an adult male not far over 

 the border in eastern Burma, January 27, 1933. He describes the 

 soft parts as follows: Iris dark brown; bill black; legs pale pinldsh 

 flesh. 



The immature female from Khun Tan was taken August 24. It is 

 molting from the spotted juvenal plumage into the postjuvenal and 

 the change is almost completed. The juvenal plumage is still retained 

 on the head, chest, sides of breast, mantle, and wing coverts. 



No suitable material is available for comparison. 



This pitta has been taken in northern, central, and western Siam, 

 but it has not been taken farther to the southwest than the Petchaburi 

 district, where it has been reported by Gairdner.*^ Herbert reports 

 a nest and five eggs found by his collector at Cliiengrak Noi, central 

 Siam, June 14, and gives a description of them." 



The form ranges from the sub-Himalayas of Bhutan to eastern 

 Assam, Cachar, Tippera, Chittagong, and Manipur to southern 

 Tenasserim and east to northern, western, and central Siam.

Pitta cyanea aurantiaca Delacour and Jabouillb, Bull. Brit. Orn. Club, vol. 48j 

 p. 130, 1928 (Bokor, South Cambodia). 



Two females, Kao Bantad, Krat, December 22 and 29, 1929; three 

 males and one female, Kao Sabap, October 23-November 22, 1933. 



This form can readily be distinguished from P. c. cyanea by the 

 grenadine-red instead of scarlet nape. 



It has been taken also in southeastern Siam by de Schauensee, who 

 reports it from Chantaboon," but Kloss took it at Klong Menao many 

 years previously.*^ 



The form is confined to southeastern Siam and southern Cambodia. 



In the mountains of southern Annam and mountains of Laos a 

 related form P. c. willoughhyi Delacour, is found. It differs from 

 aurantiaca in having the blue of the chest more purplish, the chest 

 tinged with peach red, and the nape a deeper scarlet even than in 

 P. c. cyanea and consequently deeper than in aurantiaca.
