This specimen differs from the previous form (tephrocephalus) in 

 having the forehead warbler green, the white spot on the second 

 outer tail feather less extensive, and the eye ring broken above. No 

 material has been available for comparison, but the specimen agrees 

 with La Touche's description.* It measures: Wing, 52.5; tail, 38; 

 culmen, 9 mm. 



If correctly identified, it is an addition to the Siamese list. 



The form breeds in the mountains of southeastern China (Fohkien) 

 and migrates to southern China (Kwangtung), Tonkin, Lower Laos, 

 and North Annam for the winter; it has been taken also in south- 

 eastern Yunnan in migration.
