Laying eggs and geographical location (new versus old world) do not determine whether a snake is a boa or a python.

Difference between boas and pythons include:

(1) With one exception, boas do not have a supra-orbital bone. All pythons have this bone.

(2) Not all boas have labial pits and if they do, they are located between the labial scales. Pythons, on the other hand, have theirs centered on the labial scales.

(3) The premaxilla (an area of the jaw) of boas are without teeth, while the premaxilla of most pythons are toothed.
