BIRDS FROM SIAM AND THE MALAY PENINSULA 291 



spotted breasts in the first winter plumages that later wear off. I 

 am inclined to the latter view. 



This form occurs from southern Tenasserim and southwestern Siam 

 north to the Raheng district, western Siam, thence east to eastern and 

 southeastern Siam and southern Indo-China. 



Herbert " reports it nesting in central Siam in May with eggs laid 

 about the middle of the month; he has one record for June 5 and one 

 record of )"oung being fed by the parents on April 29. 



Robinson '^ records D. p. malayensis from Koh Lak, but a female in 

 the l.'nited States National Museum from this locality is nearer D. p. 

 2)aradiseus. He "* records D. p. paradiseus from Koh Chang, Klong 

 Yai, and Klong Menao, southeastern Siam. 



The United States National Museum possesses specimens of D. p. 

 paradiseus from Trang Bom, Cochinchina and Daban, southern 

 Annam. I think Delacour and Jabouille.^* are in error in assigning 

 sj)ecimens from these localities to D. p. malayensis. It would give an 

 almost impossible range for the latter, being cut in two by D. p. 

 paradiseus. 



DISSEMURUS PARADISEUS RANGOONENSIS (Gould) 



Edolius rangoonensis Gould, Proc. Zool. Soc. London, 1836, p. 5 (Rangoon, 

 Burma). 



Two females, Khun Tan, August 30 and September 2, 1930; one 

 male, Doi Hua Mot, August 20, 1934; one male, Muang Pai, Decem- 

 ber 27, 1932; one male, Sobpung, December 21, 1932; one male, Ban 

 Den Muang, on the Mekong, February 25, 1929; one male, Nakon 

 Panom, on the Mekong, March 8, 1929; one immature male and one 

 immature female, Lat Bua Kao, August 10, 1929; one female, Ta 

 Fang, January 17, 1933. 



This is a larger bird than D. p. paradiseus with a longer and more 

 pronounced crest and the twisted spatula at the tip averaging longer. 

 The three males measure: Wing, 165-173 (168.7); outer tail feathers, 

 335-380 (358.3); middle tail feather, 134-148 (141.7); culmen, 26-29 

 (27.8) mm. The female from Ta Fang: Wing, 164; outer tail feather, 

 370; middle tail feather, 150; culmen, 30 mm. The two females from 

 Khun Tan are immature and have not been measured. 



This form ranges from central and south central Burma to the 

 southern Shan States and northern and northeastern Siam. 



The male from Ban Den Muang and the male from Nakon Panom 

 agree with the northern specimens. Both localities are on the Mekong 

 below Vientiane. The two immature specimens from Lat Bua Kao
