Rivero and Richard Thomas PART I. DESCRIPTION By Ernest E. Williams Museum of Comparative Zoology and Juan A. Rivero University of Puerto Rico, Mayaguez On June 18, 1963, Jnan Rivero was collecting at Cerro La Punta at an approximate elevation of 1200 meters when his wife and son, who had separated from the rest of the party, shouted that they had what appeared to be a new species of lizard. The animal was first seen in the axilla of one of the outer leaves of the bromeliad Vriesia {Thecodactyllum) sintenisii, which al-though usually epiphytic, was growing abundantly, together with Guzmania herteroniana, on the forest floor alongside the road. Although the cloud forest is fairly heavy in this area, trees and tree ferns had been cut for about 10 or 15 meters along the margin of the road, leaving an open although some-what shaded strip on each side. It was in the marginal area between the forest and the cleared area that the new anole was collected. When capture of the specimen was attempted, it jumped out of the bromeliad and climbed a small bush nearby. The move-ment was described as slow, but the observers are not certain if it walked, jumped or crawled. Search for other specimens in and out of bromeliads was fruitless.
