Regardless, the similarity of microornamentation in the lampropeltines in general and in Pantherophis specifically stands in stark contrast to the variation in microornamentation reported among congenerics and closely related genera from other colubrid
tribes, or within other families of snakes (e.g., Agkistrodon, Chiasson et ah, 1989; Crotalus and Sistrurus, Stille, 1987; Nerodia, Thamnophis, Chiasson and Lowe, 1989).
Male-male ritual combat in the colubrid
snake Chironius bicarinatus from the Atlantic Forest, southeastern Brazil.
Most Liophis snakes are known for their ingest preference for frogs; however, they are characterized among xenodontine colubrids
for being generalist species (Vitt 1983).In this note, I report the first case of cannibalism in Liophis lineatus.
Based on these survey efforts, it appears that the current herpetofaunal diversity of this Texas National Guard site is characterized by a subset of reptiles and amphibians and a lack of particular species (e.g., large colubrid
snakes) when compared to herpetofaunal surveys of other Travis County sites and potential species known to occur in the county.
These signals are likely to render a calling frog conspicuous to visually-oriented predators, though only two species of pit vipers and a colubrid
snake species are recorded as preying on these frogs (Hartmann et al.
Imantodes cenchoa (Linnaeus, 1758) is a neotropical colubrid
commonly known as blunt headed tree snake, and shows a special ability of moving quickly among branches (Greene).
The black pine snake (Pituophis melanoleucus lodingi) is a colubrid
snake that is historically endemic to longleaf pine forests, ranging from southwestern Alabama to extreme eastern Louisiana.
Texasophis (Squamata:Colubridae), an extinct,archaic colubrid
snake genus, is important in that Texasophis galbreathi from the early Oligocene (Orellan) of eastern Colorado represents one of the first appearances of the huge family Colubridae in North America (Holman l984a).
Timing of courtship in two colubrid
snakes of the southern United States.
Madagascar also has 7 endemic species of iguanas, a few snakes (3 boas, 8 blind snakes [typhlopids] and 50 colubrid
snakes) and some tortoises.
