THREE FINGERED BURROWER Hemiergis decresiensis (Cuvier, 1829)
This 13 cm skink is found in highland parts of NSW and Victoria, and lowland areas in south east South Australia.
It is most common in rocky localities, where it is usually found during the day sheltering under rocks, logs and other ground debris. This species has effectively no climbing ability. 2-5 live young are produced in late summer.
Little is known of the biology of this species, although it is believed to be nocturnal and insectivorous.

The above was from the book Australian Reptiles and Frogs by Raymond Hoser and now available on a fantastic CD-Rom along with a vast amount of other information, papers and the like on reptiles, frogs and other wildlife.
