The Illinois Natural History Survey Amphibian and Reptile Collection contains approximately 24,000 catalogued specimens, representing 55 families and over 550 species (51% Amphibia, 49% Reptilia). The geographical emphasis is Illinois (75%). This is the result of the efforts of Phil W. Smith, who collected specimens from 1935 to 1949 for his comprehensive study "The Amphibians and Reptiles of Illinois," published in 1961. In addition to the Illinois material, the INHS collection also houses specimens from 45 other U.S. states, Canada, the Caribbean, Mexico, South America, Asia, Africa, and Europe. Most notable among these are specimens collected by P.W. Smith from California (1943-1952) and Mexico (1957-1965), specimens of S.A. Minton from Pakistan, Mexico and Texas and specimens from Thailand collected by R.W. Larimore (1963).
