Gyldenstolpe 36 adds the locality Khun Tan; de Schauensee " met 

 with it at Chieng Dao, 4,500 feet, and at Chiengmai; Deignan '^ 

 records it from Doi Angka. Evidently it is not a common bird in 

 northern Siam. 



The form ranges from eastern Burma and the southern Shan States 

 to Tenasserim, Pegu, and Arakan and eastward to northern Siam. 

 A related form, P. o. castaneiceps Delacour and Jabouille, occurs in 

 Tonkin and another, P. o. bolovenensis Delacour, in southern Laos. 



PITTA CAEBULEA CAERULEA (Baffles) 



Myiothera eaerulea Raffles, Trans. Linn. Soc. London, vol. 13, p. 301, 1822 

 (Sumatra). 



One female, Kao Soi Dao, Trang, January 23, 1934. 



Dr. W. L. Abbott collected one male and one immature female at 

 Lay Song Hong, Trang, August 20 and December 2, 189G; and one 

 male at Telok Besar, Tenasserim, March 18, 1904. 



The immature female is about half grown and was collected August 

 20. It may be described as follows: PUeum clay color, lighter on the 

 forehead; feathers of the crown and nape blackish at the base and 

 edges, giving a flammulated appearance; hindneck and sides of neck 

 clay color, with the black bases of the feathers showing through; 

 throat and sides of face cinnamon-buff; a loral streak and postocular 

 extending back to the neck blackish; upperparts fuscous; tail, almost 

 hidden by the coverts, deep orient blue; chest fuscous-black; breast 

 hair brown, the feathers fringed with cinnamon-buff; belly hght buff; 

 under tail coverts dusky ; wing coverts dusky drab with a bluish tingo, 

 border and tip light buff; primary coverts and primaries fuscous- 

 black, the latter dull bluish gray on the outer web, border and tip 

 narrowly edged with light buff; outer secondaries similar to the 

 primaries; tertials dull grayish blue. 



This is somewhat different from the young described by Stuart 

 Baker ^^ but his description is probably taken from older birds. 



Robinson and Kloss *° say that this form is rare in the Malay States 

 but becomes commoner farther north, as they secured several speci- 

 mens from Trang and record two from Tasan, Chumporn. It breeds 

 in the Malay States, however, as Robinson ^' records a half-grown 

 young obtained early in November at Pelarit, Perils. Baker " records 

 it from Maprit, southwestern Siam, which is about as far north as it 

 has been obtained in Siam.
