Land mollusc List: Kevin Bonham 
Laomavix collisi, Pedicamista coesus, Paralaoma sp. 
"Knocklofty", Paralaoma discors, Pernagera officeri, 
Helicarion cuvieri, Caryodes dufresnii, Succinea australis. 
Also exotic slugs Milax gagates and Deroceras 
reticulatum. 
I was surprised to find this was the first South Bruny 
record of Paralaoma discors, which is common on North 
Bruny. The most interesting record was Pedicamista 
coesus, normally found in much more exposed coastal 
environments. This was the second time I'd found it in a 
saltmarsh, the first being the club's trip to Lutregala in 
2005, its only other confirmed Bruny record.
