rufous and are thereby easily distinguished from M. I. panamensis, which 

 extends from the Caribbean coast of Colombia at least as far up the Mag- 

 dalena as Algodonal.

The capture of a typical ma,le of this form at Algodonal on the Magda- 

 lena River is especially interegting as indicating how far up the river the 

 coastal fauna, extends.

An evidently not common inhabitant of the Tropical Zone of the Pacific 

 coast which, in slightly modified form, extends in to Antioquia. The Buena- 

 vista, Nariiio, female may be considered as topotypical, and two females 

 from San Jose essentially agree with it. A female from Puerto Valdivia 

 has the marks on the throat whiter and, with three males from the same 

 locality, the tail more rufous. These four birds thus approach specimens 

 from eastern Panama. I have, however, seen no authentic specimens of 

 Iwmosticta, and if the eastern Panama specimens should prove to repre- 

 sent an undescribed form, doubtless it would be desirable to refer the Puerto 

 Valdivia specimens to it rather than to nigricauda.

A female from Nare, near Puerto Berrio on the Magdalena, is doubt- 

 less to be referred to this form. It is decidedly less rufescent, more oli- 

 vaceous above than a Panama female.
