Abstract

An explicit means of calculating the expected number of species [E(S"n)] and the variance of (S"n) in a random sample of n individuals from a collection containing N individuals and S species is presented. An example illustrates a new use of E(S"n): determination of the sample size required for any desired degree of accuracy in collecting species known to occur in a particular area.
