The edges of ranges of these j9 have been plotted on one map, fig. 6. It s evident from this map that the ranges of he various species are not uniformly shin- gled over the state but that the range edges )f many tend to coincide. Some areas are â elatively uniform ecologically and have ew species reaching the edges of their â anges therein. Fig. 6 demonstrates the va- idity of fig. 5. The Sand Areas.âThe areas of sand )rairie, Avhich are relatively small, are. Fig. 6.âLimits of distribution of the am- phibians and reptiles of Illinois. Each line represents the edge of range of a species. In some areas, lines coincide. chiefly in central and northern Illinois. The largest area extends along the east side of the Illinois River from Woodford County south to northern Scott County. Smaller sand areas occur in Jo Daviess, Carroll, Rock Island, Whiteside, Mercer, and Hen- derson counties, along the east side of the Mississippi River; in Ogle and Lee counties; in Winnebago County; in Kankakee and Iro- quois counties. Small areas of sandy loam occur in Lawrence, La Salle, and Lake coun- ties. A typical sand prairie habitat is shown in fig. 7. The most abundant reptiles of the sand areas are Cnemidophoriis sexUneatus, Pituo- phis melanoleucus sayi. Coluber constrictor flaviventris, Heterodon platyrhinos, Hetero- don nasicus, Terrapene ornata, and Tri- onyx muticus. The distinctive species of amphibians and reptiles are Pse udacris streckeri illinoensis, Kinosternon flavescens spooneri, and some of the reptiles mentioned as abundant are also characteristic.
