Measurements (in millimeters). 



Remarks. — In the national Museum Collection are examples of O. 

 7narinoratus from the Bogota region (the type locality of the species) and 

 from Panama, which do not appear to differ in any way, but all Chiriqui 

 examples (the present series, and one specimen in National Museum 

 collected by Arce) are \ery much darker in color and otherwise different, 

 and represent quite a distinct form. There are many other cases among 

 the birds of this region of a species ranging from Bogota to Panama with- 

 out change, but in Chiriqui being replaced by a different, representative 

 form.
