has since given in a tabular form an account of the Paradoxides 

 beds of Andrarum. Tliey are arranged and termed by him as 

 follows. 



Agnosti Icevigati strata. 



Selenopleura^ strata. 



Paradoxidis Davidis strata. 



Paradoxidis Hicksi strata. 



Paradoxidis Wahlenbergi strata. 

 Of these the " Selen opleurns strata" correspond to the "An- 

 drarum limestone" and to those above termed by me strata with 

 Paradoxides Forchhammeri. "Paradoxidis Hicksi strata" are equi- 

 valent to the Westrogothian strata with Paradoxides Tessini, 

 The other two divisions do not occur in Westrogothia. The 

 strata with Paradoxides Davidis are, as far as hitherto known, 

 peculiar to Scania. "Paradoxidis Wahlenbergi strata" have not 

 been fbiind in any other locality in Sweden, but they occur in 

 Norway; the Paradoxides occurring in these strata is, as far as 

 can be made out from the imperfect materials I have myself 

 collected or seen in the museum of Lund, identical to the Pa- 

 radoxides Kjerulfi, which I have found in Norway, in a horizon 

 underlying that of Paradoxides Tessini. ^) This undermost part 

 of the Paradoxides beds may therefore be termed the strata with 

 Paradoxides Kjerulfi. 



Of special interest are also the Primordial rocks of the island 

 of Oland, which have been made known chiefly by the labours 

 of Mr. Sjögren. -) The Paradoxides beds are divided by him 

 inte two divisions, of which the lower, consisting of arenaceous 

 flagstones, is characterized by Paradoxides Tessini, the upper, 

 consisting of greeni^h shales with intercalated calcareous and 

 arenaceous beds, by Paradoxides ölandicus. Some time ago I 

 found, from rock specimens collected by Dr. Wallin and con- 

 taining Brachiopoda characteristic of the strata with Paradoxides 

 Forchhammeri ^), that there occurs also a third division. Since 

 then I have myself visited Oland and found the strata 

 with Paradoxides Forchhammeri at Södra Möckleby. They are
