Meracomelon subloriolianum, 
1890. Helix sublorioliana Pilsbry^ Man. Conch., (Tryon) 2nd 
Ser., Vol. VI, p.l47, pi. 58, figs. 10-12, December 16- 
Flinders Range, South Australia.. 
Though Pilsbry’s species has been regarded as the same as 
the preceding, the localities are widely separated and in this 
group geographical variation is very pronounced. From Carrie- 
ton a series of smaller shells with the spire less elevated, the 
umbilicus more open, and a beautiful distinct granulose sculpture 
is seen, and this extends across into New South Wales. A speci- 
men similar was collected many years ago in the Maldigo Hills 
by (Sir) D. Mawson. This smaller elevated form may be called 
extensum subsp. nov. PI. I, fig. 7. 
Meracomelon loriolianum. 
1863. Helix lorioliana Crosse, Journ. de Conch., V^ol. XI, p.273„ 
pi. IX, fig. 6, July 1. Mountains behind Spencer Gulf, 
South Australia. 
Meracomelon broughami. 
1875. Helix broughami Angas, Proc. Zool. Soc. (Lond.), 1875, 
p.389, pi. XLV, ff. 4, 4a, Oct. 1. Port Lincoln, South 
Australia. 
Meracomelon Cassandra. 
1864. Helix cassandra Pfeiffer, Proc, Zool. Soc. (Lond.), 1863, 
p.527, April 20 1864. Murray Cliffs, South Australia. 
Figd. Cox, Mon. Austr, Land Shells, p.50, pi. XIX, fig. 8, 
'May 1868 (type figured by Angas). 
In collections a smaller thin whitish shell sometimes very 
faintly banded, granulose above, smoother below, with the um- 
bilicus more open bears the name moorundia?ia Tate with local- 
ity Tailem Bend. It seems distinct from cassandra and I have 
seen a published figure bearing the name, but the source of the 
illustration has not yet been traced. PI. I, fig. 28. 
Meracomelon meridionale. 
1903. Thersites {Badistes) meridionalis Gude, Proc. Mai. Soc. 
(Lond.), Vol. V, p.262, pi. VII, figs. 5-7, April. South 
Australia. 
A series apparently named through Gude’s Influence are of 
medium size, up to 25 mm., with the spire flattened, the last 
whorl with the periphery rounded, the mouth open, the umbilicus 
narrow and half hidden have the juveniles strongly keeled.
