lorhynchus, Gallinago and Thamnophilus, and have found the stom- 

 achs of other specimens full of beetles and other insects ; while one 

 examined contained parts of small fish, and another the hair and 

 bones of some small mammal. 



A considerable variation was observed in the color of the soft 

 parts. A female taken at Caicara July 4, 1898, had the eye dark seal 

 brown ; skin about eye cinereous ; bill plumbeous at base, blackish at tip ; 

 cere pale pea green ; feet Naples yellow. Another female, taken on the 

 same date, had a light seal brown eye; bill blackish at tip changing

Rare. Four specimens, two pairs, were taken in the vicinity of 

 the falls of Atures on my first expedition, and an adult male was 

 taken at Caicara, July 4, 1907. In the stomach of the last were found 

 the remains of a Ground Dove, ChaemcpcUa. Berlepsch and Hartert

 where. 



Eye seal brown ; bill slate black, greenish plumbeous at base of 

 mandible; feet chrome yellow, claws black.
