The western yellow-bellied racer (Coluber constrictor mormon), [1] also known as the western yellowbelly racer [2] or western racer, [1] is a snake subspecies endemic to the Western United States, including California, Oregon, Idaho, Nevada, New Mexico, Utah, Montana and Colorado. [3] [4] It is a subspecies of the eastern racer. It is nonvenomous [5] and is recognized by its long and very slender shape. [6] [7] It is visually similar to the eastern yellow-bellied racer, which is also green, blue or brown with a recognizable yellow underside. Also named for its color, the western yellow-bellied racer is also gray with red or brown blotches when young. [8] [9]
The milk snake or milksnake, is a species of kingsnake; 24 subspecies are currently recognized. Lampropeltis elapsoides, the scarlet kingsnake, was formerly classified as a 25th subspecies, but is now recognized as a distinct species. The subspecies have strikingly different appearances, and many of them have their own common names. Some authorities suggest that this species could be split into several separate species. They are not venomous to humans.
Pituophis catenifer is a species of nonvenomous colubrid snake endemic to North America. Nine subspecies are currently recognized, including the nominotypical subspecies, Pituophis catenifer catenifer, described here.
