Size of the terminal 

 primary. 



10th primary of Chamcea more 

 than 3 cm. in Ipuffth. 



The size of the 10th primary 

 varies very irnich. In 

 Cyclorhis it is reduced to 

 only one half of the length 

 oftbe9tb ; in Vircoaolitaria 

 it is hardly 2 cm. long, 

 •whilst in Vireosylvia it ia 

 frequently reduced to a 

 small, pointed feather of 

 1 cm. in length. 



Eopsaltria seems occasionally 

 to possess an upper 11th 

 covert. 



The 11th primary is very 

 distinct ; only in L. minor 

 it is absent, but its upper 

 covert is present. In 

 L. 7ninor alone the 10th 

 primary is much short- 

 ened, and the tip of the 

 wing is formed by the 9th. 

 All the other Laniina^ 

 have rounded-oflf wings, 

 and the 10th primary is 

 i-i the length of the 9th. 



Including Promero2)s. 



The lltb primary is generally 

 very small, its upper covert 

 is perhajjs occasionally 

 absent.
