 Ornismya heliodor Bourc, Rev. Zool., 1840, p. 275 (Bogotd,). 



I am unable to discover any constant difference either in form or color 

 between topotypical females of Choetocercus heliodor and C. homhus. Wholly 

 on geographical grounds, therefore, I refer a female from San Agustin to the 

 former. A female from Mirafiores on the western slope of the Central 

 Andes, cannot, however, be disposed of so satisfactorily, since the locality 

 has faimal affinities with both Ecuador and the Eastern Andes. Under the 

 circumstances, I can see no valid reason for the generic separation of C. 

 homhus (see Oberholser, Proc. U. S. N. M., 1902, p. 341, remarks under 

 " Polyxemus homhus") since the characters ascribed to it are sexual rather 

 than generic.

I can find no constant racial differences between our Pacific coast speci- 

 mens and others from Bogota. Ecuador specimens (P. c. cequatorialis 

 Berl.), which our Pacific coast birds might be expected to resemble, are not 

 available.
