Argus bipunctatus, Wood, Ann. May. N. II. (4) viii. p. 67 (1871) ; 

 Elliot, Man. Phas. i. pi. 13 (1872). 



This species is still known only from a portion of a primary 

 wing-feather from a male bird, which is now preserved in this 

 Museum ; but it is so perfectly distinct both in its markings and in 

 the shape of the shaft of the quill from either of the above species 

 that one can have no hesitation in recognizing it as belonging to 

 a distinct species, in spite of the somewhat fragmentary evidence. 



The general colour of this feather is similar to that of a primary 

 quill of A. argus and A. grayi, but there is a reddish-brown 

 band minutely dotted with white on the outer as well as the inner 

 web. These bands extend over a large proportion of both the webs ; 

 the shaft is remarkably narrow and attenuated.
