Etymology

The specific name, barnetti, is in honor of Burgess Barnett (1888–1944), who collected the holotype and paratypes. Dr. Barnett was Curator of Reptiles at the London Zoo (1932–1937) and Superintendent of the Rangoon Zoological Gardens (1938–1944).[3]

Description

Bothrops barnetti is patterned in white and black triangles. Males usually grow to 120 cm (47 inches) in total length (including tail), whereas females are quite smaller and thinner. The body is heavily shaped and stocky.

Common names

English common names for B. barnetti are Barnett's lancehead[4] and Barnett's pit viper.[5] In Peru it is referred to as cascabel, cascabel falso, macanche, sancarranca, and zancarranca.[4]

Geographic range

Bothrops barnetti is found along the Pacific coast of northern Peru. It occurs at low elevations in arid, tropical scrub.

The type locality given is "from the mouths of Quebradas Honda and Perines, between Lobitos and Talara, northern Peru".[1]

gollark: What do you mean you "perceive" time as discrete? You mean you *arbitrarily think so*, or what?
gollark: Quite a lot.
gollark: > The Planck time is the unique combination of the gravitational constant G, the special-relativistic constant c, and the quantum constant ħ, to produce a constant with dimension of time. Because the Planck time comes from dimensional analysis, which ignores constant factors, there is no reason to believe that exactly one unit of Planck time has any special physical significance. Rather, the Planck time represents a rough time scale at which quantum gravitational effects are likely to become important. This essentially means that while smaller units of time can exist, they are so small their effect on our existence is negligible. The nature of those effects, and the exact time scale at which they would occur, would need to be derived from an actual theory of quantum gravity.
gollark: Oh, no, never mind, that's not it.
gollark: ... you mean the Planck time or something?
