SILURIAN BIVALVED MOLLUSCA OF VICTORIA. 
that the fauna present in these beds has a strong Devonian 
aspect, which abnormal feature has led Mr. R. Etheridge, jun., 
and other Australian palaeontologists to refer to such assem- 
blages as Siluro-devonian.

Observations. — Our Australian specimens present no dif- 
ferential characters by which they can be even varietally sepa- 
rated from the well-known European species. Numerous 
examples of C. cornucopia?, from Bohemia in the National 
Museum collection help to confirm the opinion of Sowerby and 
others regarding the identity of that species with C. interrupta. 
Although Sowerby ’s specific name ( interrupta ) is almost 
universally used for this form, it must unfortunately be set aside 
for the earlier described C. cornucopia) of Goldfuss. The 
specific name C. interrupta, given by Sowerby (not Broderip, 
as Fischer in his “Manuel de Conchyliologie,” gives it) was not 
published until two years after that of Goldfuss’ description. 
There was no previous reference to, nor description of, ,C. inter- 
rupta, as Murchison would lead one to suppose (see’ his foot- 
note Silur. Syst., p. 61/); for turning to the Proceedings of 
the Geological Society of London, Vol. II., under date January 
1834, _ p. 13, the reference given by Sowerby and Murchison, no 
allusion to C. interrupta is found, while iii the Table facing p
