Twenty-eight specimens : Bonda, Mamatoco, Santa Marta, Funda- 

 cion, Punto Caiman, Dibulla, and Rio Hacha. 



There is some individual variation apparent, affecting the intensity 

 of the tawny color on the throat and the amount of spotting on the 

 flanks. The type-locality of the present form, according to Sclater, 

 is Cartagena, whence came the specimens collected by Haeberlin con- 

 stituting Wagler's types. 



An abundant bird throughout the whole of the littoral Tropical Zone, 

 except in the forested section of the north coast, being most numer- 

 ous in the drier portions. It prefers the open scrub, with scattering 

 trees. It is very sluggish and stupid, sitting quietly for long periods, 

 and is very easily approached. The natives call it "pajaro bobo " 

 (foolish bird). 



Mr. Smith sent in a set of three eggs, collected at Bonda, May 17. 

 They are " clear dull white, sub-spherical." They were found in the 

 clay nest of Furnarius I cue opus ex His. 



169. Hypnelus ruficollis decolor subsp. now 



Six specimens : Rio Hacha. 



The Rio Hacha birds differ from the Santa Marta series proper in 

 their paler coloration throughout. The upper parts are paler, duller 

 brown, and the lower parts are also paler, less buffy, nearly white in 

 fact. The ochraceous wash on the throat is conspicuously paler and 

 less extended, and the nasal plumes are usually dull whitish, with little 

 01 no buffy tinge. The new form thus varies in an opposite direction 

 from Hypnelus ruficollis coloratus, of the humid section south of
