Marta region, specimens from the region to the southward turning out 

 to be P. argyrotis. The series includes a chick (No. 41,770, Cincin- 

 nati, April 7), which is buffy brown below, the throat grayish white, 

 the abdomen dull white; wings dusky, with a buffy spot at the tip of 

 each feather ; upper parts varied with two shades of brown, the top 

 of the head brownish black, enclosing an irregular patch of chestnut ; 

 tail varied with chestnut and black. Nos. 42,116 (June 2) and 42,424 

 (July 6) are older birds, beginning to show the adult characters, the 

 general coloration duller, however. Adults are fairly uniform in their 

 characters. 



Like Chamcepetes sanctcr-marthcc, this Penelope is essentially a 

 Subtropical Zone species, but ranges a little lower down, being found 

 commonly as low as 3,000 feet, and extending up to 6,000 feet, rarely 

 higher. It seems to keep in the trees most of the time, seldom being 

 flushed from the ground.

Twelve specimens: Las Tinajas, Bonda, Don Diego, and Minca. 



These agree with Costa Rican specimens, and are very uniform in 

 their characters.

This species is a Tropical Zone form, ranging far below P. colom- 

 biana. It is found from sea-level up to about 2,500 feet, but' is more 

 abundant in the coastal plain, and especially in the humid forests of the 

 coast to the northeast of Santa Marta. It was particularly numerous 

 at Don Diego; in fact, nowhere. has the writer seen any species of this 

 family so abundant as was this one at that point. As many as forty 

 or fifty birds could be encountered in a half day's tramp through the 

 woods. It was very abundant also at Valencia, in the valley of the 

 Rio Cesar, in early August, 1920, and was noted as far east as Loma 

 Larga. Only rarely is it seen on the ground, feeding as it does more 

 on fruit and berries in the tree-tops. The margins of lagoons, such 

 as abound in these lowland forests, are one of its favorite haunts.
