The distinctness of this species from M. exsul is mainly based 

 upon its having the wing coverts without spots, M. • " ha- 



wing coverts distinctly spotted with white." The single Bp 

 men in the collection has the wing coverts almost unspotted, 

 but in my specimens from Panama they are very distinctly 

 marked with small white spots. In one Panama specimen the 

 entire under plumage is black, a little plnmbeons on the abdo- 

 men. 



Two examples, male and female, in the S. In>t. Bins., col- 

 lected on the Atrato, and labelled as M. exsul by Mr. Cassin, 

 have the wing coverts marked with larger and ra aspic n- 



ous spots; in the Panama specimens the spots are confined to 

 the small coverts, but in those from the Atrato the spo mpy 

 the ends of all the wing coverts; the Atrato birds arc lig 

 colored and appear as if they had been exposed to the weather, 

 these may be the true M. exsul.
