Above black narrowly striped with white ; rump greyish ; con- 

 cealed dorsal patch white ; wings block edged with white ; tail black 

 tipped with white : beneath white striped with black ; under wing- 

 coverts white : whole length 3'5 inches, wing 1-9, tail U-2. Female. 

 Above like the male, but head and neck rufous with faint black 

 stripes : beneath reddish cinnamomeous, paler on the belly. 



Hah. Panama, Colombia, Ecuador, Amazonia, and Guiana. 



The examination of this extensive scries has induced me to 

 reunite M. multostriata to M. surinamensis. M. multostriata was 

 based on what I now consider to be the adult male of this species, 

 and what I regarded as the female of M. multostriata is simply the 

 young male. As all three forms and many intermediate ones are 

 represented in 8])ecimcns from Panama, Guiana, and Colombia, I 

 think there can be little doubt that this view is correct. But it 

 would seem that the female of the Amazonian form (J/, surina- 

 mensis multostriata) is generally more or less striped beneath.
