10 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 122 



Of the 45 stomachs examined, only 1 was empty of food, suggesting 

 that most A. lineatopus catch enough food to keep their digestive 

 systems working most of the time; however, this can be said only 

 of the period when they were collected — early in the dry season, a 

 period when insects appeared abundant. 



A captive A. lineatopus will live at least several days to a week 

 without food, so presumably in the wild an individual could survive 

 short periods of famine. I rarely saw A. lineatopus catch something 

 to eat, and I have the impression that most days it catches only a 

 few insects and some days perhaps none at all. 



In contrast to this slow rate of feeding is the response of A. lineatopus 

 to food offered them. In my study area, these lizards became very 

 tame and freely took insects tossed to them from a few feet away, 

 running several feet to do so. In a typical session of 45 minutes one 

 afternoon, I tossed insects of moderate size into an area of about 

 fom* square yards. During this time, 17 insects were captured by 

 eight different lizards, two of them catching 3 insects and one catch- 

 ing 4. This suggests that the slow rate of feeding usually seen is 

 not because A. lineatopus are satiated but because suitable insects 

 are not available. 



We saw in the field no thin or emaciated individuals among these 

 lizards. 



The wide variety of prey taken by A. lineatopus means that availa- 

 ble food is distributed throughout the habitat and is not densely 

 concentrated in certain areas. Several lines of circumstantial evidence 

 indicate that probably few, if any, established resident A. lineatopus 

 starve to death but at the same time that a superabundance of food 

 is not available to them. 



Water. — Probably all the water A. lineatopus requires, beyond 

 that present in its food, it gets by licldng drops of dew or rain from 

 leaves and twigs with the tip of its tongue. The only report I know 

 of lizards having difficulty seeming water is Evans (1951), who 

 reports Ctenosaura pectinata making long excursions to drink. 



Rain is a frequent occmTence around Kingston. Even in the dry 

 season when no rain falls, dew forms almost every night and remains 

 in the shade until mid- or sometimes late morning. Water is thus 

 available to A. lineatopus almost every day. 



Anolis lineatopus were only occasionally seen to drink in the field 

 but in cages they were seen to drink frequently. 



As I sat watching some marked A. lineatopus one afternoon, a light 

 rain began to fall. Only one, an adult male, reacted. He chmbed a 

 branch to an orchid and licked several times at one of the wet leaves. 



An A. lineatopus, which woidd eagerly take tossed insects, com- 

 pletely ignored the drops of water that formed when I watered the
