A Taxonomic Study of the Middle American Snake, Pituophis deppei

"A Taxonomic Study of the Middle American Snake, Pituophis deppei" by William Edward Duellman is a scientific exploration that untangles the complexities of the *Pituophis deppei* snake, especially those slithering through the state of Michoacán in Mexico. The study meticulously gathers information from on-site observations, detailed inspection of museum specimens, and a deep examination of past writings to sort out species and subspecies. The book organizes the relationships within the *Pituophis deppei* group, looking closely at how their shapes and colors differ, and presents proof of different species and subspecies by studying many museum snakes, field notes, geographical locations, and information on their scales and colors.
