Excerpt from Type Specimens of Reptiles and Amphibians in the U. S. National Museum As biologists know, an important function of a natural history museum is the preservation of those specimens from which new forms of life are described. Many museums have collections of such type material, the National Collection, in the United States National Museum, being among the largest. The value of such specimens is equally obvious since they serve as a standard with which later field collections can be compared, in order to validate the original claim to novelty and to establish the range and variation of the form.
