BIRDS FROM SIAM AND THE MALAY PENIi^SULA 395 



Beside the differences between this species and P. hrunneus pointed 

 out under that species, the present bird is slightly smaller. No differ- 

 ences are noticeable between a small series from Sumatra and that 

 from the Malay Peninsula. 



The range extends from Sumatra and a few of the surrounding 

 islands to a few of the islands south of Singapore and thence north 

 through the Malay Peninsula to Trang in Peninsular Siam. Robinson 

 and Kloss ^ state that the latter is the most northerly record loiown 

 to them. 



The Bornean form has been named P. s. 'perplexus.^^ Other forms 

 have been named from the Natuna and Anamba Islands. 



PYCNONOTUS BRUNNEUS BRUNNEUS BIyth 



Pycnonotus hrunneus Blyth, Journ. Asiat. Soc. Bengal, vol. 14, p. 568, 1845 

 (Malacca). 



Two males, Patalung, July 7, 1929; one female, Haad Yai, July 12, 

 1929; one immature male, Tha Lo, Bandon, September 27, 1931; one 

 male and one female, Wat Kiriwong, July 25, 1928. 



Dr. W. L. Abbott took the following in the Malay Peninsula: 

 Three males and two females, Pulo Langkawi, December 3-6, 1899; 

 two males and one female, Pulo Adang, Butang Island, December 16, 

 1899; one male and three females, Trang (Lay Song Hong, Septem- 

 ber 1, 1896; Chong, January 23, 1897; Trang, January 28, 1897, and 

 March 2, 1899); Smgapore Island, May 17, 1899; one female, the 

 Dindings, Straits of Malacca, April 16, 1900. He gives the soft parts 

 as: Iris red or orange-red; bill black, pale at base; feet fleshy brown, 

 claws dark horny brown. 



Dr. Smith's specimens are paler above and below than any taken 

 by Dr. Abbott, but the former were taken in summer when much 

 bleached, while the latter were taken in winter or early in spring 

 before fading had commenced. 



This species and P. simplex closely resemble each other, but the 

 latter is paler, less huffy below; under tail coverts and bend of wing 

 naphthalene yellow instead of chamois and iris white. 



The wing in seven males from the Malay Peninsula measures 

 83.5-87 (85.5) mm; seven females 77-84 (80.6) mm. 



The immature male from Tha Lo, Bandon, resembles the adult 

 but is darker above, the pileum snuff brown instead of light brownish 

 olive, the underparts much huffier. 



P. h. hrunneus ranges from Mergui, Tenasserim, south through 

 Peninsular Siam to Singapore, Sumatra, and some of the adjacent 

 islands. Robinson and Kloss '^ record specimens from Tung Pran,
