Geographic range

B. pictus is found along the coast of Peru, at altitudes from sea level to 1,800 m (5,900 ft).[2]

Description

Adults of B. pictus may attain a total length of 31 cm (12 in), which includes a tail 4.3 cm (1.7 in) long.

Dorsally, B. pictus has a pale brown ground color, overlaid with a series of large brown black-edged squarish blotches, which may merge to form a thick wavy or zig zag stripe. On each flank is a series of smaller roundish blotches of the same color as the dorsal blotches. There is a dark streak from behind the eye to the corner of the mouth. Ventrally, it is yellowish with brown dots or spots.

The strongly keeled dorsal scales are arranged in 21 to 23 rows at midbody. Ventrals 157-172; anal plate undivided; subcaudals divided, 40-74 pairs.[1]

gollark: The old versions, I mean.
gollark: The FS functions *themselves* would work okay, but stuff which used them seemed to keep them in scope or something.
gollark: I couldn't get FS virtualization to work properly without erasing and reconstructing the environment.
gollark: Also, there are no comments?
gollark: It has a process manager, keyboard shortcuts, a copy of the CC BIOS somewhere, plus the traditional viral infection capability.
