Out of the total of forty species there are but seven which do not 

 occur in the Lower Lyckholm and, so far as has been determined from 

 the field-study, the fauna is the same as that of the lower beds as dis- 

 played at Lyckholm, Hohenholm, Pallokiill and Paope. 



Froiti glacial boulders on Gotland Dr. Carl Wiman has collected 

 fossils of Lvckholm age.^ These boulders were no doubt derived 

 from strata outcropping beneath the Baltic and with the boulders 

 of Lyckholm limestone were others from the Borkholm. He has 

 collected the following Esthonian Lyckholm fossils, of which some, 

 however, may have come from Borkholm limestones: — 



1. Acantholithus astericus. 



2. Halysites catenularia. 



3. escharoides. 



4. parallelus.
