Glyptorhagada kooringensis. PI. II, fig. 20. 
1877. Helix {Rhagada) kooringensis Angas, Proc. Zool. Soc. 
(Lond.), 1877. p.33, fig. in text, June 1. 30 miles N.E. 
from Burra i\Iines, South Australia (F. G. Waterhouse). 
F'igd. Cox, Proc. Linn. Soc. N.S.W., Vol. II, f:.1062, 
1887 (animal): this belongs to pecuniosa. 
This species varies in the opposite direction from the pre- 
ceding as the type is not unlike silveri, but wth the last whorl 
prominently keeled.' Alany specimens are available which arc 
stronglv keeled, notably flattened and larger, sculpture stronger 
and umbilicus wider and these are here named pecuniosa, PL II, 
lig. 10, the general name '‘Kooringa’’ being given as locality. 
Mannahill is mentioned in one case, while a series from Pandappa 
Springs agree exactly with the type form, indicating pecuniosa to 
have a more northern range. 
Glyptorhagada asperrima. 
1901. Xanthomelon asperrirnum Hedley, Trans, Roy. Soc. South 
Austr., \ol. XXIX. p.l64, 3 text figs., December. Mann 
Ranges, Central Australia. 
This is similar in form to the preceding pecuniosa, but the 
sculpture of separated tubercles is very different. 
Glyptorhagada euglypta. 
1899. Glyptorhagada euglypta Tate, Trans. Roy. Soc. South 
Austr., Vol. XXIli, p.241, pi. \T, figs. 3 a c, December. 
Anabama, 100 miles north-east from Burra Burra, South. 
Australia (Brown). 
This simulates the Kangaroo Island shells in form, being 
somewhat Hat-topped, with a peripheral keel following an ante- 
peripheral groove, but rounded below. 
Glyptorhagada bordaensis. 
1880. Helix bordaensis Angas, Proc. Zool. Soc. (Lond.), 1880, 
p.419, pi. XL, fig. 3, October 1. Kangaroo Island, 
South .Australia. 
Genus Divellomelon. 
1933. Divellomelon Iredale, Rec. Austr. Miis., \'ol. XIX, p.51, 
August 2. 
Orthotype Thersites hillieri Smith. 
The acutely keeled very flattened shell of many whorls has 
a peculiarly thickened lip and a minute umbilicus: it does not 
resemble any other Australian shell and the sculpture is so ob- 
scure that its relationship cannot be deduced. It is placed here 
temporarily on account of its keeled form resembling that of some 
species of Glyptorhagada,
