DESCRIPTION OF BARS AND SPOTS, OCTOBER 1904. 



In this bird the 



1 do not find more than 13 feathers. The last 6 are secondaries (8-13). The others (1-7) are tertials. 

 I have examined this bird once before, but could find only 13 feathers. I think now that this is the true number. 

 aa No. (0) ( = fig. 2, this figure. ED.) agrees in this respect.
