Twenty-seven specimens : Bonda, Mamatoco, Dibulla, Rio Hacha, 

 and Santa Marta. 



With regard to the proper name of this form Dr. Oberholser and the 

 writer have reached a conclusion differing from that recently pub- 

 lished by Dr. Chapman. The matter may be briefly summarized as 

 follows. In 1847 Cabanis described a bird under the name Formici- 

 vora intermedia, stating that his specimens came from Cartagena, Co- 

 lombia, and the Aragua Valley,- Venezuela. In 1914 Dr. Chapman 

 received a number of specimens from the upper Magdalena Valley 

 which were clearly distinct from Santa Marta birds, assumed by him 

 to be typical intermedia, doubtless by reason of their coming from a 

 region so close to Cartagena. The Magdalena Valley form, which 

 Dr. Chapman accordingly described as new under the name Micro- 

 rhopias grisea hondec, differs from M. intermedia- mainly in the color 

 of the female, which has the under parts plain buffy, unspGtted. Males 

 of the two forms are practically indistinguishable. Recently Dr. Chap- 

 man has discovered that the Cartagena form is the same as that in- 

 habiting the upper Magdalena Valley, instead of that from the Santa 

 Marta region, as he had supposed. He has accordingly proposed to 

 reduce hondec to a synonym of intermedia, and to call the form with 

 the spotted-breasted female cano-fumosa. It seems to us that these 

 changes are inadvisable and unnecessary. The whole question hinges
