 N. Lawrence from the old Lion Hill Station on the railroad, was 

 described as a new species under the name E. pectoralis, as it was not 

 recognized that it was a migrant (see citation above). Three others 

 collected by McLeannan, now in the British Museum (Natural 

 History), are labeled Panama without other locality. One originally 

 was in the Salvin-Godman collection, the other two in the Sclater col-

 W. W. Brown, Jr., October 16, 1900, at David, Chiriqui. We have 

 another, a female, received from Colonel F. S. Blanton, taken at
