Todd-Carriker : Birds of Santa Marta Region, Colombia. 317 



described by Dr. Allen : " The nest is similar in position, structure, 

 and materials to the nests of Formicivora [Microrhopias] intermedia, 

 but is of course larger, having a diameter across the rim of about 3j4 

 inches and a depth of 2j/^. It is suspended by the rim to the fork of 

 a small thorny branch, and is rather openly woven of some species of 

 wire-like grass and coarser plant-stems, without lining, but decorated 

 on the outside with scattered tufts of plant down. 



" The eggs are white, with profuse markings of prune purple at the 

 greater end, which in one egg nearly cover the surface, but are much 

 more sparse on the other egg; the pointed half is without spots in both 

 eggs."

It is a mistake, in the writer's judgment, to treat this form as a sub- 

 species of S. canadensis, from which it differs in several important 

 particulars. Moreover, as will be shown in another connection, their 

 respective ranges approach very closely, if they do not actually over- 

 lap, with no signs of intergradation. S. pulchellus is a species of the 

 littoral Tropical Zone of Colombia and Venezuela. It was described 

 from Cartagena in the former country, and soon thereafter recorded 

 from the Santa Marta region by Sclater. Specimens from near the 

 type-locality in the collection of the Carnegie Museum agree with
