THE FRESHWATER MOLLUSCA OF VICTORIA 
109 
Localities. — Bairnsdale (Brit. Mus., from W. F. Petterd) ; 
Omeo ( J. A. Kershaw, collected by A. W. Howitt) . 
Vernacular Name. — The Victorian Pond-Snail. 
Observations. — In his description, Smith states that he has 
seen only two specimens, and remarks : “ It is much narrower 
than L. hrazieri or any of the Australian species of the genus. 
Of course it is impossible to say if either of these shells be 
adult ; but, judging from the appearance of the columella and 
the callosity upon it, I am inclined to believe that such is the 
case.” 
Two specimens from Omeo in my cabinet confirm Smith’s 
opinion that the shells described are adults and not the 
juvenile form of another species.

Vernacular Name. — The Freshwater Paper Shell. 
Observations. — An oblong-ovate, pale horn-coloured, very 
smooth and shining shell. The columella fold is slender ; the 
inner lip widely and thinly spread. Myxas replaces the 
familiar Ampliipeplea, for as Kennard and Woodward (Pr. 
Mai. Soc. Lond., xvi, 1924, p. 125) remark: “the true date of 
publication of S. Nilsson’s Ilistoria Molluscorum Svecice 
proving to be 1823 instead of 1822 (as stated on the title page 
(antea, p. 23)) causes his genus Amphipeplea to yield place 
on ground of priority to Myxas of Leach. Leach’s name was 
given currency by J. Sowerby in his Genera of Recent and 
Fossil Shells, No. vii, published June 29, 1822 (article 
‘Limnea’ (p. 3)), where 'Myxas, Leach’s MS.’ appears as
