Abstract
Various numerical coefficients have been employed in comparisons of taxa or bioassociational units, especially in studies involving large arrays of multivariate data. Nomenclatural and conceptual difficulties have arisen from the translation of coefficients from variable-oriented (R-mode) to case-oriented (Q-mode) use. This paper points out the conceptual relationships and some of the properties of coefficients expressing similarity or difference between units defined by binary data.

Not only is the distribution lognormal, but the constants or parameters seem to be restricted in a peculiar way, and they are not fixed, but they are interlocked.

D degree of popularity (P) is newly defined herein in the following formula: P=N/S(n-1) Where, N stands for the frequency that one species is concurrently obtained together with other species of this group from the same locality in each zoogeographic division, n for the total number of species examined and S for the number of investigation.

Sudden developments in methods for quantifying the classificatory process in systematics appear to stem from a growing dissatisfaction with the arbitrariness and subjectivity of the customary taxonomic procedure and would also appear to.

The major problems of geographical (as opposed to ecological) biogeography are the determination of the main patterns of distribution, and elucidation of how those patterns came about, as it applies to the species of terrestrial mammals of North America.
