This species is similar to P. macleannani of Panama and Yeragua, 

 "but is considerably brighter and richer in color on the underparts, 

 back, rump, and wings. The edges of the black-spotted feathers of 

 abdomen, under tail-coverts, back, etc., are similar in color to the sur- 

 rounding parts, instead of pale, buffy white, as in P. macleannani. 

 There seems to be no difference in size between the two forms. 



The series examined consists of eleven specimens, five of P. satHrata, 

 and six of P. macleannani. The former are from Nicaragua and Costa 

 Rica, the latter from Yeragua and Panama.
