in the Siamese bird. The wing in the Khun Tan Mountain female 

 measures 95.5 mm; the female from Khun Tan, 94 mm. The Khun 

 Tan female is grayer above and the pileum is barred rather than 

 spotted as in the other female and the Tenasserim male. The two 

 males from Khun Tan have the pileum barred rather than spotted. 

 In one the crossbars are white with scattering small white spots; in 

 the other the crossbars and spots are fulvous. Tlie wings in the two 

 males measure 90 and 86 mm. 



The male from Sriracha has the mantle russet and unbarred; only 

 the scapulars are barred with blackish; the pileum olive-brown with 

 scattering fulvous spots; the feathers along the bend of the wing 

 beneath j^rimrose j^ellow. It is evidently an immature bii'd. The 

 male from Khun Tan, with the wing 86 mm., has the carpal feathers 

 yellowish and is probably a young bird also. 



The female from Kao Sabap is the darkest above of any of the 

 specimens taken by Dr. Smith, and the bars on the back are a deeper 

 fulvous; the throat, juguium, center of the breast, and bend of the 

 wing are light sulphur j^ellow. It is quite difi'erent from the other 

 specimens and may represent a diiTerent form, but owls are very 

 variable. 



The form ranges from Nepal to eastern Assam and south to Burma, 

 Siam, and the Malay Peninsula, east to Indo-China, and southern 

 China. 



A pair from Fukien are grayer above and have paler neck collars 

 than in the Siamese series. 



Gyldenstolpe '* has recorded this owl from Khun Tan and Pah 

 Koh in the north; Robinson ^^ from Kao Nong, Bandon; Robinson 

 and Kloss '^ from Tapli, Pakchan; de Schauensee '^ from Ban Jong, 

 10 kilometers south of the Shan States border. Deignan '^ reports it 

 from Doi Sutep, between 3,500 and 5,500 feet.
