Several recent papers have described ecological differences between sympatric species of Anolis in the Greater Antilles (RUIBAL 1961, COLLETTE 1961, RAND 1962, 1964, 1966). A three day visit to Curaçao in September, 1962, provided an opportunity to make field observations on a species of Anolis that occurs with no congeners. These observations suggest that it occupies a microhabitat somewhat broader than most of the Antillean species. This trip was undertaken with the financial support of National Science Foundation Grant No. 16066. Specimens collected were deposited in the Museum of Comparative Zoology, Harvard University.
