4 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 122 



Though I made repeated trips to the other parts of the island, the 

 intensive observations reported here were made in two suburbs of 

 Kingston, Barbican and Mona. 



In studying social behavior, I concentrated on A. lineatopus living 

 in small areas, marking them individually, mapping their positions, 

 and describing their behavior. They were marked by clipping the 

 terminal phalanx from one front and one hind toe, according to a code 

 (removing one additional toe allowed higher numbers). The clipped 

 toes did not regenerate but were not visible from any distance. A 

 number was painted on the back of each lizard with white paint 

 (a quick-drying amylacetate base airplane paint). This was visible 

 at a distance but each A. lineatopus had to be recaptured and re- 

 painted after each shedding. Though inconvenient, this gave us an 

 opportunity to remeasure these lizards at intervals. The clipping of 

 the terminal phalanx removed the claw but not the pad and did not 

 seem to affect the lizard's climbing or running ability. The white 

 painted numbers interfered slightly with shedding and certainly made 

 the lizard more conspicuous to me and presumably to other predators. 

 The interference with shedding however, was temporary and the 

 increased conspicuousness unavoidable. 



The lizards were measured from the tip of the snout to the anterior 

 margin of the vent by holding them along a ruler. The measure- 

 ments were recorded to the nearest millimeter, and repeated measure- 

 ments on the same individual during a short period frequently varied 

 by one millimeter but seldom by more. Throughout the paper the 

 anole sizes given are snout- vent lengths in millimeters. 



Each lizard was marked in the field as soon as it was caught and 

 released in less than five minutes in the area where it had been cap- 

 tured. Two methods were used in catching the lizards. Some 

 were noosed during the day with a running noose of nylon filament 

 on the end of a slender stick. Others were caught by hand at night 

 while they were sleeping. The latter technique is very effective and 

 is the one Cagle (1948) describes as being used by professional anole 

 collectors in Louisiana. 



The marking process disturbed the lizards, and, after being re- 

 leased, a lizard usually remained quiet for an hour or so before re- 

 suming its normal activities. 



Though the lizards learned to avoid the noose, they soon came to 

 ignore me completely, particularly if I were stitting quietly, even in 

 plain view and only a few feet away. Those in the areas where I 

 spent hours watching them became very tame and would approach 

 me without hesitation to catch an insect. One female even took 

 an insect from my fingers.
