NO. 3595 ANOLIS LINEATOPUS — RAND 55 



principal perches. Perhaps for these reasons few disputes were seen between 

 them, none with No. 11 and only two with No. 15. In one of these, No. 15 had 

 invaded the dead leaves near No. 3 to catch an insect, as he sometimes did, and 

 No. 3 had displayed to him. No. 15 displayed back and No. 3 in turn displayed. 

 At about this point No. 5 left his hibiscus and ran towards the fight. No. 15 fled 

 back to his oleander but No. 3 remained still. No. 5 returned to his hibiscus. 

 On the other occasion, both No. 15 and No. 5 had left their perches and run out 

 onto the bare dirt beyond the dead leaves in order to catch an insect. This 

 brought them close together and they displayed at one another briefly before 

 each retreated to his own area. 



(llf) In addition to these smaller and slightly larger lizards, No. 5 also came 

 into contact with three males larger than himself. One of these. No. 14, a 48 mm 

 male, had an activity range which did not overlap that of No. 5 but was near it. 

 On one occasion No. 14, for some unknown reason, left his home range and visited 

 No. 5's hibiscus, arriving when No. 5 was absent and sat there quietly. When 

 No. 5 appeared and climbed the hibiscus, he made several series of bobs at No. 14 

 who ignored them. No. 5 did not attack No. 14 but after this few minutes of 

 display ignored the motionless No. 14. 



(llg) The next large lizard with which No. 5 had contact was No. 24, a 57 mm 

 male. This male was seen off and on throughout the study period but as far as 

 I could tell never established a permanent activity range during this time. I 

 only saw one encounter between the two. I had tossed a grasshopper towards 

 No. 5, who came to the ground for it. He made several attempts, chasing it 

 across the ground and biting at it. No. 24 came towards the grasshopper, scaring 

 No. 5 who seized it and ran back to his perch leaving No. 24 sitting on the ground. 



(llh) The final lizard with which I saw No. 5 interact was No. 26, a 58 mm male, 

 who included No. 5's hibiscus in his activity range and for part of the study period 

 visited it quite frequently. Once No. 5 fled at No. 26's approach when they were 

 both on the ground. Twice No. 5 left his hibiscus when No. 26 climbed it. Three 

 times No. 26 chased No. 5 when No. 26 was sitting in No. 5's hibiscus and No. 5 

 climbed up into it, approaching him. In each of these cases No. 5 fled immedi- 

 ately. In the final interaction. No. 26 was sitting in No. 5's hibiscus and No. 5 

 was on the ground. No. 5 ran out to seize a large insect and started to carry 

 it back to his hibiscus. On almost reaching it he apparently saw No. 26, for he 

 changed course and ran part way to the fence post. Before reaching it he stopped, 

 turned and, with the grasshopper in his mouth, step-bobbed at No. 26. 



The largest male in the area. No. 13, a 60 mm adult, was not seen to pay any 

 attention to No. 5 or No. 5 to him but No. 13 seldom visited the hibiscus. 



The aggressive behavior that has been described has involved 

 so far two A. lineatopus; such encounters were the commonest seen. 

 Aggressive encounters, however, were seen between A. lineatopus 

 and other species of Anolis. 



There are a total of seven species of this genus in Jamaica, five of 

 them occurring around Kjngston. These lizards all have somewhat 

 different structural or cUmatic niches (Rand, mss.) but they all 

 overlap to a greater or lesser extent. The commonest species after 

 A. lineatopus in the study areas is A. grahami, a green species that 

 hves generally higher in the trees than does A. lineatopus. 



The adult males of the two species are about the same size but 

 rather different in shape and in color. They are quite tolerant
