BIRDS FROM SIAM AND THE MALAY PENINSULA 397 



Straits of Malacca, March 13, 1906. He gives the soft parts as: Iris 

 blue ; bill and feet black. 



Tliis smaller race of black-headed bulbul extends from TapU, 

 Pakchan, Peninsular Siam,'" south to the Malay States and Java. 

 It also occurs on Sumatra, Borneo, and Palawan, but it is doubtful 

 whether the birds from these three localities are the same as the Malay 

 race. 



BRACHYPODIUS ATRICEPS MAJOR Robinson and Kloss 



Brachypodius atriceps major Robinson and Kloss, Journ. Federated Malay 

 States Mus., vol. 11, p. 55, 1923 (North Cachar, Assam). 



One adult male and one immature female, Koh Chang, April 5, 

 1924, and March 10, 1930; one male, Lat Bua Kao, August 11, 1929; 

 one male, Pak Chong, November 27, 1927. 



Dr. W. L. Abbott took an adult male on Victoria Island, Tenas- 

 serim, January 5, 1900. He gives the soft parts as: Iris blue; bill 

 black; feet brownish black. 



The males from Lat Bua Kao and Pak Chong are a hghter, less 

 greenish yellow on the chest and back, and somewhat larger than 

 Peninsular Siam (Trang) specimens. Whether these differences would 

 hold in a larger series is problematical. 



Two males from Vientiane, Laos, collected by Dr. Smith present, 

 presumably, a color phase; one is cadmium yellow on the underparts 

 and raw sienna above with a dusky undertone to the back and chest, 

 and the second is assuming the same plumage but has not advanced so 

 far. The adult male from Koh Chang is in a plumage approximating 

 the brightest Vientiane male below, but the back and tail are citrine; 

 the black subterminal tail band broader and the yellow tail tip much 

 reduced. The bird of southeast Siam and French Indo-china may 

 belong to a different form. No birds from northern Siam have been 

 examined. 



Gyldenstolpe ^^ reports it from Muang Pre. De Schauensee^^ took 

 it on Doi Sutep and later at Chiengsen and Chiengmai.^* Deignan 

 says it is uncommon on Doi Sutep at 2,700 to 3,000 feet. Robinson 

 and Kloss ^^ record a male from Namchut, Pakchan, Peninsular Siam, 

 v/hich is probably the southern limit in this direction. On his third 

 expedition de Schauensee ^^ took specimens at Nakon Nayok, Sriracha, 

 and Chantabun; the record from Nakon Sritamarat without doubt 

 belongs to B. a. atriceps.
