Bulletin No. 24 of National Museum gives check list of North American reptilia Ancistrodon Contortrix. Dr. Albert Ginther, who furnished the article for The Encyclopedia Britannica, calls the “Copperhead” Cenchris-Contortrix, and considers it very similar to the Trigonocephalus family, but smaller in size, generally found near the watercourses, closely related to the Cenchris Piscivarus, which is the water-snake or crater-moccasin.

The Cenchris family belongs to the temperate parts of North America, and its venom is of a deadly nature.

In 1890, Kent moved to Pennsylvania to take a position as Dean of Professors at the Post-Graduate Homeopathic Medical School of Philadelphia.
