The Victorian naturalist . red.

Bacchus Marsh This site is located about nine kilo-metres south-west of the town ofBacchus Marsh on an unnamed tri-butary of Parwan Creek. It was dis-covered by Miss Kerry Hein in akaolin pit owned by her family. From this locality have come aboutfifteen skulls, twelve jaws, andnumerous skeletal elements of smallindividuals referrable to the genusDiprotodon. Only a few other siteshave as many well-preserved speci-mens of this genus. The small size ofthe individuals is not simply because 200 Vict. Nat. Vol. 93 Fig. 4. Right lateralview of skull ofWiprotodon sp. fromBacchus Marsh,Victoria. cm viewmen as the sample consists of juvenile animalsonly, for obvious adults with all teethfully erupted and in a worn conditionare present. Whether the size of theindividuals warrants their being separ-ated as a distinct species from otherspecimens of Diprotodon must awaitdetailed study. From this material itwill be possible to extract informationabout the anatomy of Diprotodon thathas never been described, such as thestructure of the auditory region. Suchinformation should prove useful infurthering our understanding of therelationships of this genus to otherdiprotodontids as well as other mar-supials. The deposit from which the speci-mens came appears to be a channel orseries of channels which have cut intoan older kaolin deposit. These chan-nels, besides containing material re-worked from the kaolin deposits, havecoarse quartz sands and blocks ofbasalt that were derived from a flowthat caps the present surface through which the Parwan Creek is cut.
