TWO NEW ANT THRUSHES 

 One half natural si~e 



The more evenly colored bird is Miller's antpitta {Grallaria milleri Chapman), named in honor 

 of Mr. Leo E. Miller of the American Museum, and was found in the Temperate Zone at 10,300 feet, 

 near Quindio Pass, Cauca, Colombia. 



The lower bird is the second new species, Allen's antpitta (Grallaria alleni Chapman), a dis- 

 covery made while the Chapman Expeditions were working in the Subtropical Zone at Salento, 

 altitude 7000 feet, in the Central Andes. This species was named after Mr. Arthur A. Allen, of 

 Cornell University. 



Of the family of ant thrushes (Formicariidfe), the expeditions collected 83 per cent of the 124 

 species known in Colombia. These small active birds living in dense undergrowth are more difficult 

 to study and collect than even the humming bird.s. The various members of the family are distri- 

 buted throughout the four life zones, but with far the greatest number in the Tropical Zone; namely, 

 82 species, Tropical Zone, 17 Subtropical, 7 Temperate, and 1 Paramo
