NO. 3595 ANOLIS LINEATOPUS — RAND 43 



In the consummated courtships seen, there was relatively little 

 display and the whole process seemed very casual. All of the copu- 

 lations I observed between marked lizards occurred within the home 

 ranges of the lizards involved. For example, at Barbican (figs. 4, 6), 

 an adult male (no. 1) was seen in copulation with three females (nos. 

 16, 59, 145), all of whose home ranges widely overlapped his. None 

 of these females was seen to copulate with any other male though 

 this may happen. Among the hzards on an isolated tree (fig. 3), one 

 female was seen to copulate with the adult male and also, on another 

 occasion, with a smaller (ca. 47 mm) but obviously adult male. The 

 activity range of the large male overlapped that of the female while 

 the activity range of the small male overlapped that of the female to 

 some extent. 



The following description from my field notes illustrate these 

 consummated courtships: 



29 October — Bo,rbican. No. 3, adult male, was sitting on a fence post and 

 No. 18, an adult female, on the adjacent fence post about 7 feet away. They 

 had been sitting in these spots for at least J-^ hour ignoring each other. The male 

 displayed occasionally: bobbing first, then continuing to bob he began to flash 

 his dewlap, stopped bobbing, and continued flashing dewlap, then stopped; a few 

 bobs were given without any dewlapping. The female moved several times but 

 I saw no display on her part. Then, with no obvious preamble No. 3 climbed 

 along the barbed wire from his post to hers. He stopped on the wire for a moment 

 then proceeded to her post, approached her from behind and straddled her with 

 both fore and hind legs and seized a tiny bit of the loose skin on the back of her 

 neck and they walked together a few inches down the post. They stopped and 

 he twisted the base of his tail under hers and apparently inserted his left hemipenis. 

 Shortly he released his hold on her neck. They remained stUl except for two short 

 series of bobs by the female. After perhaps 2-3 minutes they separated, both 

 dragged their vents on the post and then the male returned along the wire to his 

 original post. 



Once the male had left his original post he did not display and his 

 earlier displays seemed the usual advertisement displays. I had been 

 watching the male but was aware of the female for about a half hour 

 before the male approached her and I noticed no display behavior on 

 her part. The only unusual thing she did was not avoid no. 3's 

 approach. About an hour later these two were in copulation again. 



Before any of this happened, I had placed another female, tied to 

 a string, on the male's fence post and, though she was in full view of 

 him, he seemed to ignore her completely. 



The other 10 courtships that I saw followed this pattern almost 

 exactly, differing only in that the male occasionally stopped in his 

 approach to the female and dewlapped. In each of these I was 

 impressed by the small amount of display on the part of the male and 

 its almost total absence on the part of the female. The only move- 

 ments by the female that could be considered display were noted in
