BIRDS FROM SIAM AND THE MALAY PENINSULA 277 



GRAUCALUS JAVENSIS SIAMENSIS Baker 



Graucalus macei siamensis Baker, Bull. Brit. Orn. Club, vol. 38, p. 69, 1918 

 (Mi-nam Kabreu, Siam). 



One female, Doi Hua Mot, September 4, 1934; one female, Doi 

 Phra Chao (Mem Sawan), August 3, 1934; three males and one 

 female, Khun Tan, 4,000 feet, August 25, 1930, February 25, 1932; 

 one male, Udon, February 16, 1929; three males, Muek Lek, April 

 26, 1933; one male and one female, Muang Kanburi, April 14 and 

 September 11, 1928; one female. Bo Ploi, Kanburi, September 8, 

 1928; two males and four females, Pak Chong, February 10 and 

 August 22, 1925, May 2, 1926; one not sexed, Tha Chang, Pak Chong, 

 March 14, 1927; one male. Ban Tarn Dam, March 7, 1930; one 

 female, Nong Khor, November 11, 1926; one male. Pang Sok, August 

 18, 1926; one male, Knong Phra, April 15, 1929; one male, Nakon 

 Sritamarat, March 11, 1929. 



In the adult male the nasal bristles, the loral streak, and a narrow 

 line on the chin are black; the remaining plumage of the body is 

 dark gull gray; belly and crissum white; wings blackish edged out- 

 wardly with color of the back; middle tail feathers like the back;^ 

 outer tail feathers black tipped with grayish white, increasing in 

 extent outwardly. The female is like the male, except she is of a 

 lighter gray below and lacks the black on the lores, chin, and nasal 

 bristles, but the lores are somewhat darker than the head or throat. 

 Only the immature of both sexes are lightly barred on the breast and 

 belly with narrow bars of dark gull gray or even lighter. 



Eight of the adult males measure: Wing, 168-181 (173.6) mm. 



In the southern Malay States occurs a race that is darker, especially 

 about the throat; it also has the white on the belly much restricted 

 and almost confined to the crissum. This race is named after the 

 Larut Hills — G. j. larutensis Sharpe. It may extend into southern 

 Peninsular Siam. 



There is a male specimen (U. S. N. M. no. 304311) from near 

 Phong Saly, French Laos, taken June 11. It is in worn plumage 

 and resembles siamensis but is darker above and lighter below with 

 the whole throat dark like larutensis; it is larger than the latter, 

 however. This specimen I have assigned to G. j. larvivorus, the 

 Hainan form. It is certainly not G. j. rex-pineti, with which it has 

 been compared. 



G. j. siamensis ranges from western Yunnan through Assam and 

 Burma to Siam and southern Indo-China; in Peninsular Siam it occurs 

 as far south at least as Nakon Sritamarat, where Dr. Smith took a 

 male recorded above.
