Publisher's Synopsis
Excerpt from A Study of the Teiid Lizards of the Genus Cnemidophorus With Special Reference to Their Phylogenetic Relationships
At times overlapping color phases between insular forms appear on intermediate islands. In such cases it is usually necessary to abandon the name for the central group, retaining the two sufficiently differentiated colonies on the neighboring islands as subspecies. The placing of the synonym under the name of the nearest geographical form has almost always been followed, although the actual basis for this act is found, of course, only by a careful comparison of the characteristics of the biological units concerned.
