Mus. nostr. 



Obs. D. lacrymosce affinis, sed guttis supra et subtus mino- 

 ribus, abdomine imo fere immaculato, et tectricibus 

 alarum brunneis diversa. 



We have been unable to find a description of this species, 

 which differs from its allies in having strongly marked spots 

 both above and below, and for the most part a black bill. 

 D. lacrymosa seems to be the most nearly related to it ; but 

 in this bird the spots are both larger and more extensively 

 diffused.
