EASTERN MASTERS' SNAKE Drysdalia rhodogaster (Jan, 1873)
Found along the NSW south coast and ranges, and in the Blue Mountains west of Sydney, this snake attains 50 cm.
The scalation is smooth with 15 mid body rows, 140-160 ventrals, single anal, and 40-55 single subcaudals.
This skink feeding snake is usually active by day, and is mostly found either when active or sheltering under ground litter, particularly human rubbish. Where it occurs it is often found in large numbers.
Mating occurs in the cooler months with about 4 live young produced during summer, measuring about 10 cm at birth. The young snakes are much darker in colour than their parents. In NSW the young are reproductive at 3 years old.

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.
