BIRDS FROM SIAM AND THE MALAY PENINSULA 321 



GARRULAX STREPITANS Tickell 



Garrulax strepitans Tickell, Journ. Asiat. Soc. Bengal, vol. 24, p. 268, 1855 

 (Tenasserim) . 



Nine males and two females, Khun Tan, 3,000-4,000 feet, October 

 2, 1929, August 28-September 8, 1930, February 14-March 4, 1932; 

 five males and four females, Doi Nangka, November 3-11, 1930, 

 April 25 and May 4, 1931; one male and one female, Khun Tan 

 Mountains, 3,000 feet. May 17, 1933; one female, Doi Hua Mot, 

 August 14, 1934. 



The above series shows considerable variation. The breast and belly 

 vary from neutral gray with a saccardo unber wash on the flanks to 

 a snuff brown with a narrow border of gray around the brownish-black 

 jugular patch. The pileum varies from mummy brown with the fore- 

 head black to a cinnamon-brown with little or no black. 



Williamson ^^ records it from Si-sawad, western Siam; several 

 collectors have taken it on Doi Sutep from 3,500 feet to the summit; 

 de Schauensee ^^ obtained a small series at Chiengmai and Chiengdao 

 and says that it is a bird of high elevations, where it keeps to the 

 densest part of the evergreen forest. 



The form ranges from Tenasserim to southwestern and northern 

 Siam. 



GARRULAX FERRARIUS Riley 



Garrulax ferrarius Riley, Proc. Biol. Soc. Washington, vol. 43, p. 190, 1930 

 (Kao Kuap, near Krat, Siam). 



Two males, Kao Kuap, near Krat, December 27, 1929. 



In the original description this species was compared with 6. 

 milleti, a species of the Langbian region of southern Annam. As 

 specimens of the latter may not be available to Siamese investigators, 

 I give a more complete description oi ferrarius: 



Head, throat, and jugulum clove brown; lores and ear coverts 

 black; a white spot on sides of neck posterior to the ear coverts; 

 breast and upper back deep quaker drab; lower back, rump, closed 

 wing, and flanks olive-brown; tail blackish brown above washed with 

 olive-brown. Wing, 124-128; tail, 116-118.5; culmen, 25.5-25; 

 tarsus, 41-43; middle toe, 25-26 mm. 



Kao Kuap belongs to a group of mountains the main chain of which 

 extends eastward into Cambodia. It seems strange that the nearest 

 relative of this species should be G. milhti, a mountain species separated 

 from ferrarius by several hundred miles. 



The species was named in honor of Dr. Hugh M. Smith.
