 times as long as tarsus (the latter less than one-third as long as wing),

''It would be very remarkaljle should the bird from the Volcan de ^liravalU's, 

 Costa Rica, be reallj' the same as that from the Volcan de San Miguel in Salvador, 

 especially since the evidently distinct form from the Volcan el Viejo in Nii-aragua 

 (.S'. fascialus) comes between. I strongly suspect the distinctness of the Costa Rican 

 birds, and suggest the desirability of careful reexamination and comparison.
