DESCRIPTION.—Head triangular, rather broader than long. Muzzle
rounded. Eyes slightly prominent. Tongue somewhat heart-shaped,
scarcely emarginated behind. Palatine teeth very few, and with
difficulty perceptible, placed in two small groups between the
posterior nares. Body thick and broad, with numerous glandular
tubercles scattered over the surface, principally on the anterior
parts, and assuming somewhat of a longitudinal arrangement. Lumbar
glands large, round, and prominent. Legs robust and short. Toes of
the fore feet wholly separate, with a small tubercle under each
joint, and two larger ones at the hinder part of the palm. Hinder
toes, with a rudimentary membrane at the base, a small tubercle
under each joint; the first and second toes very short. A conical
tubercle at the inner, and another at the outer side of the
metatarsus.
COLOUR.—The upper surface is beautifully marbled with dark olive or
black, on a light-green ground; some of the markings assume
somewhat of an ocellated form, and approach to a symmetrical
arrangement. The lumbar glands are more strongly coloured than the
other parts, the centre being black, and nearly surrounded by a
bright line of very light green, or nearly white. The thighs are
numerously banded with the prevailing colours, and a tinge of
orange or red. Beneath pale; in some specimens blackish under the
chin.
The aspect of this species is remarkably bufonine; and this character is
increased by the numerous glandular tubercles on the surface of the
body, and pores about the parotid region. It is, doubtless, similar in
its habits to many of the toads.
