4. Euloina omnium Ang ^). A piece of a head-midsliell and of a 

 pygidium were exposed to view. 



5. Agnostas Sidenblaclhi Linrs. ^). Tliis species is represented hy 

 a head-shell. 



6. SJiiimardia iMsilla Sars ') ? 1 am inclined to range nnder this 

 head a very small pygidium, which donbtless comes from a Shu- 

 mardia-species. That I am not quite certain here, is owing to the 

 fact that it shows a lateral compression and consequently is not so 

 broad as the pygidium pictured by Moberg ^). The latter, which has 

 been produced from slate, may be somewhat flattened, whereas the 

 pygidium out of my erratic-block has probably retained its original 

 shape. It is also possible, however, that it comes from a new Shu- 

 mardia-species. According to Hennig '") such a new species is met 

 with in the Ceratopyge-zone of F. gels'ng. Unfortunately the essay in 

 which this species was to be described — which essay was shortly 

 to be published, according to that writer — , still keeps us waiting. 



7. (Jrtlds Chrtstlaniae Kjerulf). Several valves of this little 

 Brachiopode were found. 



The three first species of Trilobites are, according to Tullberg ') 

 also met with in the lowest strata of Oelaud Orthocere-lime, but as 

 this does not appear to be the case witli the othei' fossils, I do not 

 hesitate to call this erratic-block a piece of Ceratopjge-lime. 



Erratic-blocks from the Ceratopyge-zone with remains of Trilobites 

 seem to be very rare in the German and the Dutch diluvium. As 

 far as I can see, only two have been made mention of by Remele ") 

 and one by Stolley "), as most certainly belonging to this zone.
