curiosity of most of the guans. Whenever danger threatened, the 

 guacharacas would slip off through the trees, or sit quietly in some 

 dense growth where it was almost impossible to make them out. 

 Local name, Guacharaca. 



Aburria aburri Lesson. 



La Azulita, i. 



This bird was seen only near La Azulita, but at La Carbonera near 

 the Paramo Tambor, the natives spoke of its being known in that 

 vicinity. Its range probably lies between 2000 and 6000 feet. It was 

 not reported by the natives at St. Helena, near the foot of the moun- 

 tains, although the airline distance from there to La Azulita is probably 

 not over ten miles. We find no previous record of its occurrence in 

 Venezuela. 



It was said to be very abundant near La Azulita at certain times 

 of the year when special fruits ripen. From our brief observation and 

 also from what could be gathered from native hunters, it appears 

 that this bird is more or less nocturnal. On two different mornings 

 we heard its call several hours before sunrise. The specimen taken was 

 found in a tree about ten-thirty one morning and gave every evidence 

 of being sound asleep. It is said to build its nest in trees. 



Local name, Guali. 



Colinus (Eupsychortyx) cristatus Linnaeus. 



Maracaibo, 2 ; Altagracia, 2 ; Rio Aurare, 5 ; Rio Cogollo, 3 ; 

 Valera, 2. 



These quail were abundant in suitable localities from sea level to 

 6000 feet. They were found throughout the arid region around Mara- 

 caibo, in the open arid forest, on the savannas around the Rio Cogollo, 

 and in the coffee, sugar cane and com fields at higher altitudes. Their 

 habits and notes were very similar to those of our common Bob White 

 (Colinus inrginianus) , but in the more uninhabited regions where little 

 disturbed, they showed a tendency to tree when flushed. 



The two specimens from Valera are intermediate between Colinus 

 c. cristatus and Colinus c. horvathi. In the color of their upperparts 

 they are nearer horvathi while on the underparts they resemble cristatus. 

 In the valley of the Rio Motatan above Valera they were noted up to 

 an altitude of 6000 ft., but this region is separated from the Chama 

 valley, where horvathi is found, by very high mountains, so complete 

 continuity of range is not probable. 



Local name, Perdis.
