The form evidently ranges along the coast from southern Tenasserim 

 south in Peninsular Siam to Trang or a little farther. 



ZOSTEROPS JAPONICA SINENSIS Swinhoe 



Zosterops sinensis Swinhoe, Ibis, 1861, p. 331 (for Zosterops japonicus Swinhoe, 



Ibis, 1861, p. 35). 

 Zosterops simplex Swinhoe, Ibis, 1861, p. 331 (after the above, on the same page, 

 and for the same form). 



Two males, Chiengmai, November 25, 1928; one male and three 

 females, Lampang, November 17, 1928; one female, Doi Nangka, 

 November 9, 1930. 



This particular race is a much more greenish-backed bird above 

 than forms of palpebrosa, the yellow of the forehead is wider, and the 

 throat and under tail coverts are paler. It is almost certain that de 

 Schauensee's ^® records of Z. simplex williamsoni from Chiengrai, 

 Chiengdao, Chiengsen, and the southern Shan States, belong to this 

 form. 



Whether this form is resident or only a winter visitor to Siam is not 

 known, so far as I am aware. In South China it is resident, but 

 farther north it is migratory, and the birds found in Siam in the winter 

 may be migrants from farther north. 



The form is found from North China south to Burma, Siam, Laos, 

 Tonkin, and Annam. 



I follow Stresemann ^^ in placing this as a form of japonica, as this 

 seems to be the best arrangement so far proposed.
