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 palzontologists 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. cornucopie from Bohemia in the National 
Museum collection help to confirm the opinion of Sowerby and 
others regarding the identity of that species with C. imterrupta. 
Although Sowerby’s specific name (interrupta) is almost 
universally used for this form, it must unfortunately be set aside 
for the earlier described C. cornucopie 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. 617); for turning to the Proceedings of 
the Geological Society of London, Vol. IT., under date January, 
1834, p. 13, the reference given by Sowerby and Murchison, no 
allusion to C. interrupta is found, while in the Table facing p. 
13, Div. I., Ludlow Rocks, we read—*Cardiola,” Brod., a new 
genus, 2 spp. My friend Mr. C. Davies Sherborn, F.G.S., who 
* In Progress Report No. IV. Geol. Surv., Vict., 1877, p- 156, there occurs a note by 
McCoy on this and associated fossils, stating them to be of Ludlow age. Even at the 
present time we cannot speak much more definitely, but judging from the strong Devonian 
aspect of the fossils they may be even comparable in part to the Dowtonian.
