We consider this form specifically distinct from the more southern 

 D. picus. It was described by Lafresnaye in 1847 from specimens 

 purporting to come from Rio Hacha, in the northeastern corner of the 

 region covered by the present paper, his types being still extant in the 

 collections of the Academy of Natural Sciences of Philadelphia and of 

 the Museum of Comparative Zoology respectively. Some specimens of 

 the present series are decidedly rufescent below, while others are more 

 olivaceous, but this difference is apparently not dependent on either 

 locality, age, or season. Immature birds (August to October) may 

 readily be told by their darker and shorter bills, while there is a ten- 

 dency for the stripes on the breast to continue down over the abdomen. 



A Tropical Zone species, confined entirely to the lowlands and lower 

 edge of the foothills, and not often seen outside of the semi-arid sec- 

 tion or the drier parts of the forested section. It was recorded by the 

 writer at Rio Hacha, the type-locality, in July, 1920, and also at 

 Arroya de Arenas, Fonseca, and near Badillo. It prefers the thorny 

 scrub and cacti, and is never seen in dense forest. Dr. Allen describes 

 the nest as placed in an abandoned woodpecker hole in the top of a 

 dead stump, and built of a felted lining of plant-down mixed with bits 

 of plant-stems at the bottom of the cavity. The eggs are three in 

 number, pure white.
