This is the scientific name of a creature generally known under the
title of the horned-toad, though really a lizard. Its head is of a
light brown, marked with dark spots, the under part being of a dull
yellow; and is armed with long conical spines, set round the edge and
pointing backwards. The back is covered with shorter and stouter
spines, of a triangular shape, extending to the very point of the tail--
also armed with a strong row of spines, which gives it a completely
toothed appearance. The colour of this curiously covered back is grey,
with irregular bands of chestnut-brown across it.
Formidable as it looks, it is not only harmless, but never retaliates
when attacked, and remains perfectly quiet when taken in the hand. It
is also easily tamed, and learns to know its owner, and to take food
from his hand--preferring little red ants, though it eats readily
beetles, flies, and other insects. From its small, rounded form, and
the mode of sitting, it has in all likelihood gained its common name of
the horned-toad.
