I. Smedstorp. 



The first deposit to which a fairly intimate examination has been devoted, is 

 that seen at Smedstorp in SE. Skåne (see the sketch map, pag. 8). Holst, 

 who in 1892 for the first time mentions this locality, referred it, on account of the 

 find of Gardiola interrupta Sow., to the Colonus shale. Because of its relatively 

 great mixture, the fauna there has attracted much interest. Most of fossils were 

 found in a mudstone lying in the shales. The strata in question have been met with 

 little more than 1 km. W. of the church of Smedstorp, in the brinks of a canalized 

 rivulet. The Silurians of the nearest neighbourhood, those of Flagabro in the NE. 

 and of the Smedstorp railway station in the SE. are of much older geological age 

 (Ordovician); consequently the Cardiola-bearing layers of Smedstorp are rather iso- 

 lated. On my researches, I found the layers on the first known locality (on the 

 sketch map, pag. 16 marked as loc. a) nearly horizontal, possibly a little dipping to 

 W. They were accessible only in a short extent, After a slight interruption, indeed, 

 shale with mudstone reappeared about 45 m. further to NE. This place I have 

 called loc. b. Also here, the layers have fairly the same strike and dip as in loc. a. 

 If no dislocation is concealed in the interspace, the layers at loc. b might perhaps be 

 a little older than those at loc. a. The nearness of the deposits to each others and 

 the resemblance of the lithological development, to some degree, speak for this being 

 the fact. As a certain difference, however, is to be found between the faunas 

 of these localities, their fossils have been strictly kept apart from each others. At 

 loc. a 42 species have been found, at loc. b only 12. The two localities have 

 only 3 species in common, as can be seen nearer from the tabular review, pag. 

 49, where also a complete list of fossils has been entered. 16 species are new; 

 their descriptions are given in the following. 



Discina pagodica n. sp. 



Pl. I, fig. 10 a and b. 



Nearly circular in outline; apex high, subcentral, acuminate and a little com- 

 pressed from the sides. The posterior part of the shell seems to be a little more 

 convex than the anterior. No fissure observed. Surface ornamented with from 5 

 to 6 feeble terracedines, and between them very fine, irregular, concentric strise. 



Diameter 1 1 mm.
