C. Lapworth—Recent Discoveries in Sweden. 71 
succession. The following are the commoner fossils of this new 
horizon :— 
Paradoxides Tessint, Brongn. Agnostus gibbus, Linnrs, 
—— Hicksti, Salt. —— fallax, Linnrs. 
var. palpebrosus. — /issus, Lundgr. MS. 
Liosiracus aculeatus, Ang. Metoptoma Barrandet, n. sp. 
Solenopleura parva, . sp. Hyolithus, sp. ind. 
Conocoryphe exsulans, 0. sp. Lingulelia, sp. ind. 
=C. coronatus of Nathorst. Acrothele intermedia, n. sp. 
Conocoryphe Dalmani, Ang. Obolella sagittatis, Salt. 
tenwicincta, N. sp. 
—— dmpressa, NL. sp. 
Of the above species, at least four—Paradowx. Tessini, Liostr. 
aculeatus, Agnostus gibbus, and Agnostus fallaz—have been collected 
from the zone of Paradowides Tessini, under its most typical aspect, 
not only in Scania, but in Westrogothia, Nerike and in Oland. On 
the other hand, not one has certainly been recognized in the zones of 
Paradowides Bjerulfi and Paradoxides Forchammeri, which lie respec- 
tively above and below the zone of Paradoa. Tessini. 
The fossils of the Coronatus-Limestone are almost wholly peculiar 
to Scandinavia. A few of those figured by Barrande from his Etage 
C. are somewhat similar, but are not actually identical. As yet it is 
impossible to institute a comparison between the fauna of the Coro- 
natus-beds and that of any of the presently accepted subdivisions of 
the British Cambrian, from the fact that, owing to the indifferent 
state of preservation of the British species, it is as yet impossible to 
say which of them are identical with the Swedish forms. From the 
general aspect of the fauna, however, it is suggested that the syste- 
matic place of the Coronatus-Limestone is between the Menevian 
and Longmynd Groups, as these are presently defined by Dr. Hicks. 
The whole of the known species of the Coronatus-Limestone are 
described in full by the author, and illustrated in three very beauti- 
ful lithographic plates. Under his description of Acrothele inter- 
media, Linnarsson replies briefly to the strictures of Ford, more 
especially with reference to the implication that Acrothele was 
ignorantly founded upon the heterogeneous elements of the dorsal 
shell of Zingula and the operculum of Hyolithus ; and points out 
extra-Swedish examples of his genus. 
The strikingly Primordial character of the rich fauna of this 
previously overlooked Coronatus zone is apparent at a glance, and 
forms another of the abundant recent indications that the under- 
rated Cambrian system, absorbed into the Silurian by the omnivo- 
rous Murchisonians and despised and rejected by the discontented 
followers of Sedgwick, is certain to prove itself as important in the 
geological series as the better understood, and therefore more highly 
estimated systems that succeeded it. 
Like all Mr. Linnarsson’s papers, this bears upon every page the 
marks of keen research and of modest caution, combined with deep 
palzontological knowledge, and it forms a most valuable contribution 
to the literature of the Cambrian rocks.
