Pituophis is a genus of nonvenomous colubrid snakes, commonly referred to as gopher snakes, pine snakes, and bullsnakes, which are endemic to North America.
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. This snake is often mistaken for the prairie rattlesnake, but can be easily distinguished from a rattlesnake by the lack of black and white banding on its tail and by the shape of its head, which is narrower than a rattlesnake's.
Arizona elegans is a species of medium-sized colubrid snake commonly referred to as the glossy snake or the faded snake, which is endemic to the southwestern United States and Mexico. It has several subspecies. Some have recommended that A. elegans occidentalis be granted full species status.
Rena humilis, known commonly as the western blind snake, the western slender blind snake, or the western threadsnake, is a species of snake in the family Leptotyphlopidae. The species is endemic to the southwestern United States and northern Mexico. Six subspecies are currently recognized, including the nominate subspecies described here.
The long-nosed snake is a species of nonvenomous snake in the family Colubridae. The species is endemic to North America. It has two recognized subspecies. The other species in the genus were previously considered subspecies.
Cemophora coccinea, commonly known as the scarlet snake, is a species of nonvenomous snake in the family Colubridae. The species is native to the southeastern United States.

The Cape gopher snake or Baja gopher snake is a species of nonvenomous colubrid snake endemic to extreme southern Baja California Sur, Mexico. They have become increasingly popular companions for people interested in the exotic pet trade, due to their extreme color variations and relatively docile behavior. It was previously considered to be a subspecies of Pituophis catenifer. There has been controversy whether the Baja Gopher Snake is a lower classification of the Cape Gopher Snake. Some say the Baja Gopher Snake should be in a separate sub-species of Pituophis Vertebralis Bimaris, while Cape Gopher Snakes should remain Pituophis Vertebralis Vertebralis. Many people mistake the two as the same sub species and have cased some cross-breeding between the two. In captivity the bloodlines are nearly all related and breeding has become especially difficult in terms of keeping the bloodlines alive.
Pituophis melanoleucus, commonly known as the pine snake, is a species of nonvenomous snake in the family Colubridae. The species is endemic to the southeastern United States. Three subspecies are currently recognized as being valid.
Sonora palarostris, commonly known as the Sonoran shovelnose snake, is a species of small nonvenomous colubrid which is a native of the Sonoran Desert in North America.
The Louisiana pine snake is a species of large, nonvenomous, constrictor in the family Colubridae. This powerful snake is notable because of its large eggs and small clutch sizes. The Louisiana pine snake is indigenous to west-central Louisiana and East Texas, where it relies strongly on Baird's pocket gophers for its burrow system and as a food source. The Louisiana pine snake is rarely seen in the wild, and is considered to be one of the rarest snakes in North America. The demise of the species is due to its low fecundity coupled with the extensive loss of suitable habitat - the longleaf pine savannas in the Gulf coastal plain of the southeastern United States. Management activities are being conducted to promote the species' recovery.
The Pacific gopher snake is a subspecies of large non-venomous colubrid snake native to the western coast of North America.
Salvadora hexalepis, the western patch-nosed snake, is a species of non-venomous colubrid snake, which is endemic to the southwestern United States and northern Mexico.
