National Science Foundation Grant GB 2444 supported this study. On the basis of this newly examined material — so much more abundant than anything seen before — plus the collections of the Museum of Comparative Zoology, I have been able to come to the following conclusions. 1. Anolis hiporcatus Wiegmann does occur in both Colombia and Ecuador and also in Venezuela. 2. Anolis solifer Ruthven must be considered a synonym of A. hiporcatus Wiegmann. 3. A. hiporcatus Wiegmann is at least in a broad sense sym- patric with A. frascri but the sympatric populations appear not to belong to the nominate race. 4. A. hiporcatus belongs to a quite different group from A. fraseri, the relationships of which are, as Dunn and Etheridge have suggested, to endemic South American anoles. COMPARISON OF A. BIPORCATUS AND A. FRASERI. The characters of these two species — so often confused — are best compared in tabular fashion (Table 1). In many characters there is wide overlap. If in any numerical character the range. Fig. 1. Anolis fraseri, MCZ 70227.
