would be extremely difficult to arrange in any satisfactory man- 

 ner the geographical distribution of the two forms, and I think it 

 not unlikely that with a good series of examples the two would 

 run into each other without leaving any definable line of separa- 

 tion. Mr. Ridgway refers this bird from Truando in his article 

 on D. punctigula (I.e.), to D. erythrofygia Sclat., but as it has 

 no spots on the back, merely a few pale yellow lines, it is un- 

 doubtedly the same as the Cost Rica bird. Mr. Ridgway's identi- 

 fication may, however, eventually prove to be correct. At all 

 events the bird from Costa Rica separated by Mr. Ridgway is not 

 restricted to that country, as is shown by the Truando specimen. 

 It remains therefore for some one with better material at ham I 

 than I at present possess, to fix the status of the form called D. 

 punctigula.
