FIELD OBSERVATIONS ON ANOLIS OCCULTUS WILLIAMS AND RIVERO By Richard Thomas 10,000 SW 84th Street Miami, Florida 33143 Having been fortunate enough to collect the first substantial series of the newly described Anolis occultiis, I take the oppor- tunity to present those observations on habits, habitat and color repertory which were made incidentally to collecting the speci- mens. I am indebted to Dr. Albert Schwartz, without whose support the collections would not have been made, and Dr. Ernest E. Williams whose advice was to be alert for a strange and new little anole in the forests of Puerto Rico. All but two specimens of occult us collected by me were taken at night while they slept. They invariably slept on dead or leafless vines and twigs. Although the sleeping sites were usually associated with a viny or bushy tangle, frequently individuals slept on single branches which projected beyond the main mass, or on pendant pieces of vine. While sleeping (Fig. 5) the head. Fig. 5. Typical sleeping posture of Anolis occultus. was almost always towards the distal part of a twig or vine (where this could be determined). The forelimbs were flexed and the hindlimbs extended along the sleeping surface only slightly flexed. At times the fifth toe was positioned against the tail on either side, as if to hold it in place (a posture seen in some "grass anoles"). The tail was curled loosely about the vine or twig to a varying extent, sometimes completely encircling it. This characteristic prehensility of the tail enabled specimens of occultus to be identified at a glance even at a distance that would.
