Liotia Loddere, Petterd, Journ. Conch., p. 135, 1884; zd., 
Hedley, Proc. Linn. Soc., N.S.W., vol. XXIIT., 1899, p. 802 ; 
three woodcut figures. 
Localities.—Tasmania (Petterd!); South Australia, Denial, 
Streaky, and Fowler Bays (R.T.), Port Victor and MacDonnell 
Bay (A. Adcock !); New South Wales, Sydney Harbour (C. 
Hedley !). 
L. Loddere has the operculum and vitreous test of the Cyclo- 
strematide. 
From the observations of Messrs. Hedley and Pilsbry, op. cit., * 
Vitrinella liricincta, Garrett, is congeneric ; and a third species 
may be the following. 
Lodderia minima, Ven.- Woods, sp. 
Liotia minima, T.-Woods, Proc. Roy. Soc., Victoria, 1877. 
I have not seen this species, but from the description it would 
seem to be allied to LZ. Loddere. The habitat is not stated, but 
it is presumably either Tasmanian or Victorian.
