BIRDS FROM SIAM AND THE MALAY PENINSULA 263 



The male taken at Nong Kae, May 7, by Dr. Smith almost lacks 

 the chest streaks, and the light edges to the feathers above have dis- 

 appeared through wear, maldng a quite different looldng bird. 



The range of the form extends from eastern Tenasserim to central 

 Siam. 



ALAUDA GULGULA HERBERTI Hartert 



Alauda arvensis herberti Hartert, Bull. Brit. Orn. Club, vol. 43, p. 149, 1923 

 (near Bangkok, Siam). 



Five males, two females, and one unsexed, Bangkok, August 3- 

 November 3, 1926. 



Two specimens, taken August 3, are birds of the year but nearly of 

 adult size. 



This is a small dark form of skylark that I have been unable to 

 compare with A. g. gulgula. 



Williamson " found it resident at Bangkok and procured young in 

 April and May. Herbert ^* reports it nesting there from early in May, 

 or earlier, to the end of June or into July and described the nest and 

 eggs; Kloss^^ reports it from Koh Lak; de Schauensee ^° from Petrieu. 



As far as known, this form ranges from southeastern Tenasserim to 

 southwestern and central Siam.

DEUCHON URBICA CASHMERIENSIS (Gould) 



Chelidon cashmeriensis Gould, Proc. Zool. Soc. London, 1858, p. 356 (Cashmere). 



Two females, Sichol, Bandon, May 17, 1930. 



These two specimens agree fairly well with a pair from the mountains 

 of Szechwan, except the throat and chest are more grayish. This 

 seems to be a more southern record than any made so far and an excep- 

 tionally late date. The wings measure 104.5 and 108 mm, which 

 seems to be rather large for the form. Five females from Szechwan 

 measure 97-102 (100 mm). Hartert '^ gives 97-104 mm. 



De Schauensee ^^ took specimens on Doi Sutep, where it did not 

 occur below 4,500 feet; Deignan ^^ states that it occurs on Doi Sutep 

 from November to April. 



The form breeds from the Himalayas of Kashmir through the high 

 mountains to western Szechwan to Kansu, China, migrating farther 

 south to winter.
