128 BULLETIN 172, UNITED STATES NATIONAL MUSEUM 



Robinson and Kloss record a female from Chong, Trang, Decem- 

 ber 27, 1910 ^^; a specimen from Nong Kok, Ghirbi, January 6, 1918 **; 

 and specimens from Kao Ram, 1,200 feet, and Kao Luang, Nakon 

 Sritamarat.^^ De Schauensee ^° took a male at Nakon Sritamarat on 

 May 25. August Miiller ^' long ago recorded two specimens from the 

 island of Piiket (Salanga). 



Apparently it is not a common bird in Peninsular Siam. The form 

 ranges from central Tenasseiim south through Peninsular Siam to 

 Selangor. 



Chasen and Kloss *^ say that Penthoceryx sonneratii Jasciolatus 

 (S. Miiller) is found in the extreme south of the Malay Peninsula and 

 Sumatra. No specimens of this form are available for examination. 

 Penthoceryx sonneratii musicus (Ljungh) inhabits Java. A male of 

 this form in the United States National Museum is more russet above 

 and with narrower black crossbars than malayanus; below the black 

 crossbars are narrower; it is smaller, wing 106 mm. 



In a young male from the island of Tablas, Philippines, the black 

 crossbars above and below are very broad and distinct, more so than 

 any mainland bird before me (there are immatures from Raheng, 

 Siam) ; the black on the central tail feathers occupies nearly the whole 

 area and it has a purplish sheen, the russet along the borders reduced. 

 It is nearly adult. The wing measures 118 mm. 



In the Philippines the species has been recorded from Calamianes, 

 Palawan, and Tablas. ^^ Specimens from these islands probably 

 represent an unnamed form.

One male, Kao Luang, Nakon Sritamarat, July 16, 1928; two males 

 and one female, Nong Yang, near Sriracha, November 9, 1931; one 

 female, Bangkok, January 1, 1925; one immature male, Muek Lek, 

 April 25, 1933. Dr. Smith also secured an adult male at Vientiane, 

 Laos, February 20, 1929. 



The specimen marked "female" from Nong Yang differs somewhat 

 from the female from Bangkok, especially in the central tail feathers. 

 In the Nong Yang bird these are barred with bronzy green and 

 cinnamon, while in the Bangkok specimen, they are unbarred, bronzy 

 green with a purple sheen, the edges and tip cinnamon. The Bangkok
