about 2 mm. shorter ; the third about 1 mm. shorter thau 

 the fifth ; the second 2 mm. less than the third ; the first 12 

 to 14 mm. shorter than the second, and about two-thirds 

 of the length of the wing. The first primary is somewhat 

 narrower than the following ones, and slightly emarginate 

 on the inner web, towards the tip, but does not otherwise 

 differ in shape. 



In C. I. leucorrhoa the fifth and sixth primaries are 

 the longest ; the fourth, third and second are each from 

 3 to 5 mm. shorter than the preceding one ; and the first 

 is reduced to a small, narrow lanceolate feather, not more 

 than 15 mm. in length. 



? Differs in the same way as the S from C. I. 

 leucorrhoa, and the chest and sides are much duller green, 

 and the middle of the belly paler yellowish. Wing 56, 

 tail 33, bill 9 mm.
