Now, it may be pointed out that the males of the Tonkinese form in 

 the present collection do not agree quite with those of any of the above 

 forms. They differ from Ai. selieriœ sehcriœ in having the tail much shorter 

 and the difference of length between the middle and the next lateral tail- 

 feather also distinctly smaller ; from Ai. seheriœ andersoni by the shorter 

 tail and in the majority having the visible parts of the closed tail metallic 

 green suffused with violet, instead of being lilac ; from Ai. seheriœ cara in 

 having the nape never crimson ; and from Ai. seheriœ labecula in the shorter 

 tail as well as in the nape which is not crimson. 



As regards the females of the Tonkinese form, they are somewhat 

 nearer to the same sex of Ai. seheriœ selieriœ than of Ai. seheriœ cara. 

 However, they differ from the former by the tail being decidedly shorter. 

 Moreover, the under wing-coverts and axillaries are not so clear pale yellow 

 as in cara.
