(2) Phenacosaurus heterodermus is a montane anole believed to have 
branched off the anole lineage before Anolis proper. Most observations - 
made during only two days - were in roadside vegetation at a single 
locality ca 6 km SW of the village of Tenjo, north of Bogota, Colombia. 
Phenacosaurs were found primarily in two types of perches - tree 
trunks and bushes, A single individual was seen on the ground and another 
on a fence post. There was an apparent preference for small diameter 
perches near the ground, 
Body temperatures were taken for 30 individuals and ranged from 19 .0° 
to 27,8% (x = 22,10 + .67°) in a time period between noon and 2 p.m. The 
individual of 27,8% was almost three full degrees warmer than the next 
warmest and was on a fully exposed perch, Other individuals were perched 
ín or near vegetation that tended to obscure the sun. 
The behavior of the animals was characteristic - sluggish, slow moving, 
rarely making any movement to escape capture and then only by moving off 
slowly or falling to the ground, 
Miyata is currently collecting locality data for South and Central American 
anolines, with several immediate goals in mind: 
l. to map the overall distribution of the different species and to point 
out gaps in extant collections; 
2. to store the locality data in readily accessible form (as on punch 
cards); and 
3. to use the locality data to restrict the scope of certain types of 
studies he would like to carry out. 
A trial analysis, utilizing multivariate techniques, was performed on 
the Anolis faunas of the Greater Antilles, Although there were some 
ambiguities in the results, they were minor and due to problems in execution 
rather than in basic design, What Miyata hopes to do is to utilize these 
techniques to examine community structure on the mainland, in certain selected 
localities, as both a preliminary and adjunct to field work.
