(2983) Myiozetetes similis columbianus Cab. & Hein. 



Myiozetetes columbianus Cab. & Hein., Mus. Hein., II, 1859, p. 62 (Carthagena). 

 Myiozetetes texensis colombianus Allen, Bull. A. M. N. H., XIII, 1900, p. 146 

 (Bonda; Minca; Sta. Marta; Cacagualito; Palomina). 



Specimens from the Magdalena Valley agree with those in a large series 

 from Bonda in the Tropical Zone near Santa Marta which may be con- 

 sidered as typically representing this form, since it was based on specimens 

 from the Caribbean coast both to the east and west of Santa Marta (Puerto 

 Bello, Venezuela; Carthagena, Colombia). Although we have specimens of 

 columbianus from Esmeraldas and southward in the coast region of Ecuador, 

 it does not appear to have been recorded from the Pacific coast of Colombia. 

 Some specimens from the vicinity of Merida, Venezuela, mark the first 

 steps of intergradation between columbianus and similis in the slightly 

 rufous edgings to the central wing-quills and buffy tint of the wing-linings.
