HIS second part of the List of Swedish fossils, prepared by Prof. 
G. Lindstrém, contains the names of the species occurring in 
the Upper Silurian strata of that country. The principal locality in 
which rocks of this period are developed is the Isle of Gotland, 
from which place no fewer than 960 species are recorded, and, 
according to Prof. Lindstrém, this number will be considerably 
increased when all the fossil groups are thoroughly worked out. Of 
those already studied in detail the Crustacea number 183 species, 
the Gasteropoda 192 species, the Brachiopoda 150 species, and the 
Crinoidea 180 species. The Silurian strata in Gotland are ranged 
under eight divisions, corresponding approximately with the 
divisions of the same rocks in this country, and the range of each 
species in the different divisions is carefully noted. Of the other 
localities in which Silurian rocks occur in Sweden, those in the 
province of Scania have yielded 75 species, in Dalecarlia 22 species, 
and in Jemtland 48 species. G. J. H.

S is well known, the Mesozoic strata of Sweden are exposed 
in situ only in a very limited tract of the southern part of 
that country, and they are but very imperfectly represented by two 
groups of beds; a lower, belonging to the Trias and older beds of the 
Lias ; and an upper, belonging to the newer beds of the Cretaceous 
system. In the present memoir Prof. Lundgren discusses in detail 
the distribution, the petrographical characters and the fossil contents 
of these various beds, as well as their relationship to the corre- 
sponding strata in other countries. ‘The lower series of beds are 
included in (I.) the Kagaréd-group, which is regarded as probably 
of Keuper age; and (II.), the Coal-bearing beds, of Rhzetic and 
Liassic age. The interval between the Lias and the Upper Chalk 
is entirely unrepresented, and it is probable that the South of 
Sweden was a land surface at the time. The Cretaceous beds 
belong to the Lower and Upper Senonian and the Danian stages. 
A list of the literature on the subject is appended. G. J. H.
