Abstract

Evidence for a natural relationship among species, genera and higher groups of snakes has come principally from studies in comparative anatomy and geographical distribution. Fossil remains have yielded very little toward the solution of problems of interest to the taxonomic herpetologist, and genetic work with snakes has only recently been undertaken. The hemipenis has been used extensively in the classification of snakes. The present work was undertaken with the hope that possibly a comparative study of the developmental features of this organ might throw some light on the relationship among certain sub-families of the Colubridae which could not be ascertained by a study of its superficial characters alone. Even though this hope might not be realized 'it was felt that a comparative study of the morphology and development of the hemipenis in itself was highly desirable since no such work of a comprehensive nature had previously been undertaken.
