Plate 132, Figure 2. The Marbled Gecko, Diplodactylus marmoratus (now known as the Marbled Gecko, Christinus marmoratus) found in Echuca
Like all the Geckoes, these Diplodactyli are small, nocturnal Lizards, with the tips of the toes generally more or less dilated. This species is a good example of those having an apparent doubling of the greatly swollen distal ends of the toes, with the terminal joint and claw so minute as to seem hid in the notch between the two large pads.
They live on insects and worms, which they swallow whole, the oesophagus being very large. The males are smaller than the females. The tails are very brittle and easily list, reproduced with some slight differences, from the original in the form of the scales, &c.
The species is abundant in the northern parts of the colony, found lurking under the deciduous bark of trees in the day time, the brownish of purplish-ashy mottlings almost exactly coinciding in appearance with the bark, rendering them very difficult of detection except for the brightness of the beautiful bronze eye. Some specimens have the transverse, dark marbling more distinct, and with the light color less broken, while others have the pattern more complex. The under-side is destitute of markings in all the species. The specimen figured is from Echuca.
Not figured of the color of life before.
Marbled Gecko, Christinus marmoratus
Small, soft-bodied lizard, up to 70 mm long (snout-vent). Distinguished by large toe pads, flat body, and often orange specks on the tail.
Habitat and range
Arboreal. Commonly found in woodpiles, fallen timber or logs during the day. At night, can be seen around external lights, where it eats insects that are attracted to the lights. Common in suburban Melbourne, including many inner-city areas such as Fitzroy and Clifton Hill.
It is not know whether this species occurs naturally within Melbourne or was introduced in firewood shipments from more rural areas. Mating takes place late in summer, and the females retain the sperm over winter until fertilisation in the late spring to early summer. Females produce one clutch, containing two eggs.
