NO. 3596 ANOLIS LINEATOPUS — RAND 19 



small predator would probably be unable to reach a lizard wdthout 

 slialdng the perch enough to awaken it. 



Though easily awakened at night by a light or by movement of 

 the perch, the lizards are slow to leave their perches and usually 

 do so only when they are shaken quite violently. 



The sleeping sites differ sharply in character from the preferred 

 diiu'nal perches; the sleeping sites are places this species seldom 

 visits during the day except when catching an insect or when engaged 

 in a dispute mth another anole. 



Some individuals seem to use the same leaf or twig as a sleeping 

 site night after night. Most, however, are not so regular, though 

 they tend to sleep in the same bush, tree, or bunch of grass. There is 

 definitely not the same attachment to a particular sleeping site 

 that there is to the daylight perch. 



Anolis lineatopus left their sleeping places soon after it became 

 light and usually did not settle do^\^^ to sleep until it \\'as too dark 

 for them to be seen even from a few feet away. Blah (1960) reports 

 a similarly long period of activity for Sceloporus olivaceus during the 

 summer as does Hhth (1963a) for Basiliscus vittatus. Perhaps this 

 is characteristic of lizards sleeping, as these do, in exposed sites in 

 a warm climate. 



On one occasion, January 27 in Barbican, I watched a male A . lineatopus go to 

 sleep. I first noticed him at 6:13 p.m. when he ran up the stem of the croton and 

 stopped just below the terminal bunch of leaves. The sun had set but the hind- 

 scape was still bright. A minute and a half later he chmbed up among the leaves 

 and out along one of them and stopped in a typical alert position, head raised and 

 neck bent. Two and a half minutes later he flattened out against the leaf, still 

 facing its tip. Six minutes later he turned around facing the stem of the leaf and 

 flattened against the leaf. The sky was still light but the landscape dark. By 

 6:30 the first stars were out and it was almost full dark. With the flashlight I 

 could see that the lizard's eyes were still open but he was in his normal sleeping 

 position. 



Both Mertens (1939) and Rand (1962) noted in Hispaniola that 

 certain species of Anolis sleep with their hind legs flexed while others 

 sleep with these legs stretched out along the body. Anolis lineatopus 

 may sleep in either position and quite frequently a sleeping A. linea- 

 topus was found wdth one leg flexed and the other extended backward. 



Home Range and Activity Range 



An A. lineatopus seldom travels far and most of the area it visits 

 is visible to it from its usual percli. 



I use the term "activity range" for the area visited regularly during 

 the day including the usual perches but excluding the sleeping site 

 when it is outside of this area. "Home range," as used here, includes
