and thus approach the Central American form T. c. finitimum to which, 

 indeed, some of them might readily be referred. As a rule, however, 

 finitimum has the back greener, the head blacker than cinereum, and, in 

 color, the western Colombia birds are more nearly like the latter.

Six specimens from extreme southwestern Colombia agree with a series 

 of eight birds from Rio de Oro and Chone, Manavi, Ecuador, and thus in- 

 troduce this Ecuadorian form into Colombia. 



While obviously a representative of Todirostrum cinereum, its grayer 

 upperparts, paler underparts, and whitish throat are not approached by 

 specimens from the Choco region, a fact which suggests the complete de- 

 tachment of the more southern form. In size, sclateri agrees with the small 

 Central American race, T. c. finitimum, five males, having an average wing- 

 measurement of 42 mm., but the comparatively small amount of gray on 

 the upperparts of this form, make it less like sclateri in color than is true 

 cinereum.

 In addition to Lawrence's type we have five specimens from Bonda near 

 Santa Marta, four of which essentially agree with it, while the fifth, in the
