on Doi Siitep at 4,500-5,500 feet, and Gairdner " secured it in the 

 Rabeng District. 



The range of the form is the hills south of the Brahmaputra, Chin, 

 and Cachin Hills, and the hills of central Burma and northern Siam. 



Family PARIDAE: Titmice

 Parus major malayorum Robinson and Kloss, Journ. Federated Malay States 



Mus., vol. 8, pt. 2, p. 226, 1918 (Sungci Kumbang, Korinchi, Sumatra). 



Dr. W. L. Abbott took one adult male, one adult female, and one 

 immature male at Prahmon, Trang, March 21-27, 1896. 



The male has molted the tail, and the tail in the female is much 

 worn and frayed at the tip. The specimens are a deeper gray on the 

 flanks than P. m. cinereus of Java. The tail pattern cannot be com- 

 pared. There seems to be little or no difference in size. No Sumatran 

 specimens are available for comparison. 



The immature male was taken March 27 and is nearly full grown. 

 When compared with a slightly younger male of P. m. cinereus, it is 

 grayer on the flanks and the yellow tinge is very faint; the white in 

 the tail is mostly confined to the outer feather in ambignvs; the second 

 outer feather having a mere dot; the white on the second outer feather 

 of the tail is quite large and well defined in cinereus. 



This form ranges from Sumatra to the Malay States and northward 

 through Peninsular Siam probably to southern Tenasserim. There 

 seem to be few records from the mainland. Ogilvie-Grant ^^ records 

 it from Patani; Miiller from Salanga (Puket).^^ 



PARUS MAJOR ALTARUM La Touche 



Parus major altarum La Touche, Bull. Brit. Orn. Club, vol. 43, p. 43, 1922 



(Mengtz, Yunnan). 



One male, Doi Nangka, November 4, 1930; one male, Doi Hua 

 Mot, August 12, 1934. 



These specimens have been compared with P. m. tibetanus, which 

 altarum greatly resembles, but they are smaller with more of a j^ellow 

 tinge on the upper back; and with P. m. artaius to which they are 

 nearer in color of the upperparts, but one has the tail pattern of 

 tibetanus, that is, the outer tail feather mostly white except for a 

 narrow black border on the inner web; second outer tail feather with 

 a large white wedge-shaped spot, running up about halfway from the 

 tip, shaft black almost to the tip; the next three feathers with smaller 

 spots, diminishing toward the central rectrices; wing, 61.5, 63.5 mm.
