6 LINNARSSON, BRACHIOPODA OF THE PARADOXIDES BEDS. 



there immediately overlain by the Oleniis beds, the strata with 

 Agnostus la?vigatus being entirely wanting in that place. Tlius 

 the succession in the Paradoxides beds of Ohmd is: 



0. Strata with Paradoxides Forchhammeri. 

 2. » » Paradoxides ölandicus. 



1. y> » Paradoxides Tessini. 



The relative position of 1 and 2 I give on the authority of 

 Mr. Sjögeen. Diiring my visit to Oland I could nowhere find 

 a superposition showing their relation. In two places I saw the 

 strata Avith Paradoxides Tessini 13'ing immediately beneath those 

 with Paradoxides Forchhammeri. Wherever tlie strata with Pa- 

 radoxides ölandicus werc exposed, neither of the other two di- 

 visions was visible in the vicinity. 



The Paradoxides beds of our other provinces are partly less 

 iraportant than the preceding, partly very insufficiently known. 

 In Xerike the three divisions known from Westrogothia are re- 

 presented, but they are less developcd, at least the two upper 

 ones. The strata with Paradoxides Tessini are greenish and shaly, 

 with intercalated bands of limestone; the others consist, as usual, 

 of alum-schists with bituminous limestone. ^) 



In Ostrogothia no complete sections of the Paradoxides beds 

 are hitherto known. A iew vears ago I found, in some loose 

 slabs of alum-schist, some of the Ibssils characterizing the strata 

 with Paradoxides Forchhammeri and those with Agnostus lan'i- 

 gatus, and recently J have also found the same divisions in situ 

 at Palstorp and KnilVinge. 



The strata with Paradoxides Tessini and those witli Para- 

 doxides Forchhammeri \\vi\e, been found in Jemtland, '-) the 

 latter, however, not in situ, only in detached stones. Besides, 

 there occurs, for instance at Lillviken near Östersund, a non-bi- 

 tuminous schist with Paradoxides and Ellipsocephalus, the po- 

 sition of which has not yet been fully ascertained. It seems to 

 correspond most nearly to the strata with Paradoxides ölandicus, 

 but the fossils hitherto found can liardly be idcntilied with full 

 eertainty.
