Our Amphibian and Reptile Collection contains more than 251 470 specimens in 37 925 lots, most of which are fluid-preserved, with some skeletons, skins and mounted specimens. It also boasts a very good collection of dried frog skins mounted on sheets of paper, like plants; they offer a very good source of tissue for DNA extraction. Our emphasis is on geographic and life history variation of common species in Canada. Approximately 83% of the collection comprises Canadian specimens. This collection counts representatives from some 930 species in 67 families. One hundred and thirty-eight are type specimens, including two holotypes, among which one is a Canadian holotype and five are Canadian paratypes.
