BIRDS FROM SIAM AND THE MALAY PENINSULA 251 



sular birds, and if they are not S. I. lunatus they must belong to an 

 unnamed form. For the present I prefer to consider them as belong- 

 ing to the same form as birds from Burma, though I have not examined 

 any from the latter country. 



The form has been taken in northern Siam by several collectors, 

 Lowe ^° found it in small parties 28 miles east of Um Pang to the 

 Meping River, western Siam; Robinson and I^oss ^^ report it from 

 Tapli, Pakchan Estuary, and Tasan, Chumporn, Peninsular Siam, 

 which is the limit of its range to the south. They found it in dry 

 bamboo jungle at Tapli and in deeper, more evergreen jungle at 

 Tasan. Deignan ^^ reports it ranging on Doi Sutep between 2,600- 

 4,500, and de Schauensee took his Chieng Dao specimen at 4,000— 

 4,600 feet. 



The form ranges from Pegu and Karenni to southern Tenasserim, 

 the South Shan States, Burma, and northern, western, and northern 

 Peninsular Siam. 



SERILOPHUS LUNATUS STOLIDUS Robinson and Kloss 



Serilophus lunatus stolidus Robinson and Kloss, Bull. Brit. Orn. Club, vol. 40, 

 p. 16, 1919 (Kao Nawng, Bandon, Peninsular Siam). 



Tliree males, Kao Luang, Nakon Sritamarat, July 19, 1928. 



These three specimens agree with the original description in having 

 deeper-colored inner secondaries and tertiaries and the drab, less ful- 

 vous ear coverts. The rumps are also darker. 



At present this form is loiown only from the middle portion of 

 Peninsular Siam (Bandon, Nakon Sritamarat, and Tung Song)'. 



S. I. rothschildi Hartert and Butler, of the mountains of the Malay 

 States, has not been available for examination. It is said to have a 

 deeper, brighter rump and secondaries than S. I. stolidus. It may 

 extend into western Patani. 



SERILOPHUS LUNATUS ELISABETHAE La Touche 



Serilophus lunatus elisabethae La Totjche, Bull. Brit. Orn. Club, vol. 42, p. 14, 

 1921 (Hokovv, southeastern Yunnan). 



One male and one female, Kao Lem, Sankambeng Range, eastern 

 Siam, December 28, 1930; one male, Lamton Lang, June 1, 1934, 



The two specimens from Kao Lem agree fairly well with a specimen 

 received in exchange from the Paris Museum from North Annam. 

 This form is grayer and has a deeper-colored rump and inner flight 

 feathers than S. I. stolidus. The specimen from Lamton Lang is not
