forays. To measure the utilization of activity range, I recorded at 

 5-minute intervals the position of each A. lineatopus present in a 

 small area of hibiscus hedge during 10 periods of about Yi hour each 

 April 18-23. These records for each individual were compiled and 3 

 convex polygons drawn, one connecting the outermost points, the next, 

 the smallest including 75 percent of the observations, and a third, the 

 smallest including 50 percent of the records. All the records (April- 

 June) were added and a polygon enclosing them was drawn. The 

 100 and 75 percent polygons are shown in figure 9. The area of each 

 polygon was calculated. The results (table 4) show that each anole 

 spent half his time in a very small area compared with that which it 

 visited. Fifty percent of the records fall in areas ranging from 4 to 

 35 percent of the respective areas enclosing all of the census records. 

 In 9 of the 11 cases it is less than 20 percent and in 6 it is less than 10 

 percent. 



The addition of other records for AprU, May, and June made a 

 great increase in area in only 1 case. In the other 9 cases it less 

 than doubled the area. 



The principal perches of A. lineatopus and the area immediately 

 around them form what might be called the core area of the activity 

 range, following the usage of Kaufmann (1962). As he found in 

 the raccoon-like coatimundis, the core area is not only the part most 

 heavily used but also the part of the home range with the least overlap 

 with those of others (see p. 46). 



The activity range of an adidt A. lineatopus seems relatively 

 permanent and certainly shows no seasonal variation. Subadults and 

 particularly young males are much more mobile. 



In the abandoned aqueduct, that I observed, 5 adult males marked on October 

 19, were found the following June 1 and all were in the same places where they 

 had been marked. In the yard at Barbican, of the 16 adult males seen more than 

 once in September and October, 7 were still present in the middle of March. Of 

 these, 3 had shown slight shifts to adjacent areas and 4 had shown none. Of 

 those 9 which had not been seen in March, 2 were dead, but it is possible that the 

 other 7 had shifted their areas outside of the study plot. 



Of the 24 adult females seen more than once during September and October, 13 

 were seen in March. Of these, 3 had moved in the interim, all to adjacent areas. 

 Again it is quite possible that some of the females not seen in March had moved 

 rather than had died. 



Smaller shifts, which did not involve abandoning the original area, were more 

 common. Perhaps the commonest were brief excursions lasting less than a day 

 and peripheral to the usual area. These were recorded in both adult males 

 (up to 20 feet, 7-10 feet being more common), and females (up to 13 feet, 4-5 

 feet being more common). Also, not infrequently observed were shifts involving 

 the abandonment of part of the area and certain perches and extending the area 

 to new perches in some other direction. Finally, at least 2 of the females made 

 temporary shifts during the period of September to November 7, abandoning the 

 original area for an adjacent one for a few days and then returning.
