lately that during this winter he will issue a memoir, in which 
he will describe all the material he has collected for several 
years, having the kindness to send me a map, on which he 
has localized not only the Lapland area of Taconic outcrops, 
but also all the other patches of Scandinavia and Esthonia. 
British- Scandinavian formation. Until now, in Europe, 
the only other locality where the Scandinavian group has been 
found, is in Great Britain, where lately, 1888, professor C. 
Lapworth has signalized its existence on the flanks of Caer 
Caradoc (Shropshire). Besides an Holmia ( Olenellus) which 
he has previously named callavei, professor Lapworth quotes 
the following fossils : Kxitorgina., Michwitziaf and Acrothele. 
The sandstones and calcareous beds containing those fossils 
are succeeded irregularly by the Lower Tremacloc strata. ("On 
the discovery of the Olenellus fauna in the Lower Cambrian 
rocks of Britain," in Geol. Magazine, Nov. 1888, pp. 484-487, 
and reprinted in Nature, Dec. 27, 1888). 
From the dates it follows that English geologists many 
years after the discoveries of Messrs, Nathorst, Linnarsson, 
Broegger and Holm, have at last found the Holmia zone,]\xsi 
as they found only many years after Barrande's disQOvery 
of the Paradoxides zone in Bohemia, the Paradoxides beds of 
St. David ; and of course, many years after Dr. Emmon's great 
discovery of a special fauna in his Taconic systein. It is only 
just to insist on the date of discoveries in everything which 
partakes of the Primordial, because British geologists have 
assumed the naming and classifying of all the strata below 
the Carboniferous system, as belonging to them, without any 
regard to priority of discoveries by other nations and other 
geologists.^

Europe, in the same Acadio-Russian sea, on the edge of the 
terra firma of the Taconic period, another patch of Scandina- 
vian group or Holmia zone, has been recognized in Concep-
