This thematic map shows the distribution, density and types of reptiles and serpents found around the world. The upper map focuses on reptiles and the middle and bottom maps focus on serpents, with the bottom map representing venomous serpents. The darker shading represents regions that are more densely populated, and the colored lines indicate the areas in which a specific family can be found. The vignettes in the bottom corners of the sheet show the types of reptiles and serpents to be found in the "new world" and the "old world." The graphic mountain chart lists the types of animals found at various elevations in the Alps, Pyrenees, and Andes.
Keith Johnson worked in conjunction with German Heinrich Berghaus to produce the Physical Atlas, the first truly comprehensive thematic atlas. The maps from this atlas made a huge impact on cartography in general and specifically on the graphic portrayal of geographical data.
