Specimens from Port Lincoln are separable from the typical 
form as given above under the name valens pL I, fig. 16, which 
is here provided for this form, while the shells from KangaroO' 
Island are given the name neta pi. I, fig. 15, the differences being 
indicated above.

This form has a different appearance from the preceding,, 
as it is more conical, the stronger erect radial sculpture obsolete,, 
but instead there is a very fine subordinate radial ribbing, the- 
periphery strongly keeled, the base rounded, umbilicus small,, 
deep, hidden by reflected columella, outer lip sharp, thin.

Family Dipnelicidae. 
Some years ago some land shells were collected on Hummock. 
Island, and sent to Hedley for report. One of these is a very 
beautiful little shell quite unlike any known South Australian 
snail. Hedley had marked it as ^‘Paralaoma n. sp.”, but it is no 
close relation to that genus, while it somewhat recalls the Tas- 
manian shells which are referred (perhaps unwisely) to the- 
family Flammulinidae. Again from some aspects it suggests the 
family Rhytididae. Such an anomalous form deserves separ- 
ation so that the animals may be investigated by some anatomist..
