Adult Male. — Top of the head and nape dark chestnut ; upper 

 parts olive-brown, with a rufous tinge in freshly-moulted 

 specimens ; sides of head and fore-neck chestnut ; breast 

 brownish or olivaceous-grey j belly paler. Total length, 23 

 inches; wing, 8-3; tail, 10-3; tarsus, 27; middle toe and 

 claw, 2-4. 



Adult Female. — Probably similar to the male, but I have nut 

 examined any examples in which the sex has been properly 

 ascertained. 



Range. — Northern South America ; Cayenne, British Guiana, 

 Rio Negro, and Rio Branco. 



Habits. — According to Mr. C. B. Brown the native name of 

 this bird is *' Nanaquah." It is easily tamed, readily inter- 

 breeds with domestic fowls, and the hybrids are said to be very 

 pugnacious. Its native name is, of course, derived from its cry 

 of "Nannaquoi."
