We have long been reluctant to admit the distinctness of this bird from P. hematotis, 
so closely are they allied; but we do so now rather out of deference to Count 
Salvadori’s opinion. The most obvious distinction is the presence of rose-red feathers 
across the throat, but these are not always to be seen; a more certain difference, but 
one that is not easily detected, is the edging of the feathers of the crown, which is olive- 
brown rather than red-brown. There is white about the chin, which may or may not 
be constant. 
P. coccineicollaris is only found, so far as we know as yet, on the Isthmus of Panama, 
where it is crossed by the railway. A little further to the westward, at Santa Fé, the 
true P. hematotis is found. .
