 that the "gWivackeskiifer" may also contain a s|)ecies of Arionc^llns 

 (Arionelhis Priniaevns Brögger ?). 



From communications made bv Tlllberg -) and IIknmg ■') the 

 conclusion mii>ht be drawn that Arionelhis Primaevus Brogg occurrinn; 

 at Kiviks Esperöd and (lislöfs Hammar. had been sni'liciently in(h- 

 cated. I think, however, tliat this should not be done. 'I'lie list (tf 

 fossils which these two authors have drawn up with re.^ard to 

 the "oi;'ivackeskilfer" of the two places mentioned just no\v and of 

 Aiulrarum, uuist refer, in my o})i]uou, to these places laken collec- 

 tixely and noi to each separately. 1 am conlirmed in this o])inioii 

 by the fact that remains of Holniia Kjerulti Lim's (oi- of a kindred 

 species) are not mentioned by Mobkrg ") as being found at Kiviks 

 Esperiul, whereas they are mentioned by them. 



The origin of tliis erratic-block must most probably be looked foi" 

 in the eastern ])art of Schonen or in the Baltic Sea-region bordering 

 on it. That petrographically it "diifers from the ordinary ''graNackes- 

 kiffer", does not clash with this opinion, several writers infornung 

 us that the latter often changes into sandstone. The thin layers on 

 the lower side indicate that something of the kind has been the 

 case here. 



It is not likely to ha^'e come from Norway, for never was a 

 sedimentary erratic-block found in these parts, of which this may 

 be said. 



As was mentioned above, I take this erratic-block to be the most 

 interesting one of the pieces that are described in this paper. I 

 do this because it is the tirst piece connng from layers ^^illl 

 Holmia Kjerulti I^inrs that has ever been made mention of. Nowhere 

 in literature did T tiud anything about an ei-ratic-block of that age. 



\\ . Shortly before the summer-holidays of last year 1 found, when 

 visiting the loam-pit close by Hemelum, a slab-shaped |)iece of tine- 

 grained sandstone three centimetres thick, whilst its largest dimension 

 is a little more than 20 centimetres, ll is layered and contains 

 calcium-carbonate, so that with muriatic acid il gives elfervescence 

 of dioxide-carbonate. 



Owing to the large number of Glauconile-grains it contains, ihe
