tlie wing is 72 ( ? ) to 78 ( (5^ ), aud in S. p. panat/ensis it is

Obs. Two specimens were received from John Waterstradt. 

 They were marked ^ and ? , but being much alike in size, 

 are perhaps of the same sex. 



In 1903 (Nov. Zool. x, p. 10) I pointed out the differences 

 between the present form and S. ii. panayensis, which lie 

 chiefly in the longer and lighter blue feathers of the throat, 

 shorter wing, and paler upperside. I have now examined 

 additional Philippine examples and can no longer doubt the 

 distinctness of the Obi form. These birds are inhabitants 

 of the mountains and do not migrate,

 forms iu the Berlin Museum.
