Smooth, dorsal scales in 38–45 rows at midbody. Dorsum khaki-brown to yellow-brown. Males with larger anal spurs than females

Distribution. Costa Rica, to Colombia and northern Venezuela, the Isla de Margarita; and Trinidad, Tobago. Life History. An arboreal, nocturnal, forest and forest-edge boid that occasionally descends to the ground. Readily seen at night using a flashlight and searching the canopy, common in Caroni Swamp and many locations in the Northern Range. Diet includes birds, mice, squirrels, bats, mongoose, porcupine rats, and mouse opossum. Reproduction. Courtship and mating in February; 20–30 young born August.
