The prevalence of the geratologous forma of the different series in the highest 



I. - indicates that this fauna, like those of the Swiss and 



Rhone basins, is also a residual fauna, but lying north instead of south of the 



ichthonee The only definite information with regard to th< L 

 faunas of the higher northern latitudes, which I have been able to la\ hands on, is 

 the •• I 5 ' ' sche Bildungen," bj 1>. Lundgren. 1 ( B

laii'li beds in northwestern Sweden, l>ut the fossils were in bad condition and not 

 abundant in the number of Bpecies. Lundgren mentions, also, ih it these beds are 

 underlaid by an unfossiliferous bed, which he thinks is probably the equivalent of 

 the Planorbis and Angulatus beds of Central Europe. M Heberl has, in hisiuter-

It i- well known that the Lias does not exist in Central Russia, and A. Pa\- 

 low, in his article on "Russie, Bsquisse <i ologique," 1 gives an account of the 

 ssic, but mentions the Lias as occurring only in the Crimea 

 and perhaps the Caucasus, and refers these to the fauna of the Mediterranean 

 province, and not to Central Europe. Savi E. G. Meneghini, "Geologia della

number of the Arietidae. Von Rath' quotes a list of fossils from Mene- 

 ghini • main Arietidae, and he Btates that there are a number of new 

 forms; but names and descriptions of species are unfortunately not 

 usually of value in such work as we are Btrn Taramelli, in Ins mono-
