Summary. 
I. Stratigraphy. 
The Seaman Braebiopod beds, a well recognizable horizon in different parts 
of the province, are the same as the zone of Dalmanites mucronatus of Tüllberg 
or the zone of D. eucentrus of Moberg. Their stratigraphical place appears from 
the table on p. 30. 
1. The rock is a grey or bluish mudstone or shale almost devoid of lamina- 
tion, rich in small scales of mica and specially in the upper part calcareous. In 
the lower and middle parts a few thin dark layers are embedded full of quartz 
grains of varying sizes, the maximum being 5 — 10 mm. Nearly all the layers 
contain pyrites. In weathering, the upper calcareous beds change into a loose 
brown substance resembling the Backstein limestone occurring as boulders in the 
North German drift. 
2. The different areas of the Brachiopod beds are easily found on the map 
of Skåne (fig. 1, p. 7). 
At Nyhamn (fig 2, p. 9) only the lower subzone (see further on) is developed ; 
it is immediately overlain by the zone of Climacograptus scalar is. 
Röstånga. At loc. Va 1 the entire Brachiopod beds crop out together with 
the over- and underlying strata. In the Brachiopod beds we can distinguish seven 
strata the fossils of which are indicated in the lists on p. 12 — 14. — The series of 
strata at loc. III i is shown in fig. 4, p. 14. The Brachiopod beds of this locality 
belong to the boundary between the two subzones (see further on). 
Järrestad — Tommarp (SE of Skåne). On loc. 3, SE of Gisslinge bridge between 
Järrestad and Tommarp the Brachiopod beds mentioned by earlier writers are proved 
to be a great boulder of the Staurocephalus beds (fig. 5,p. 18). — At loc. 17 (fig. 6, p. 20) 
the boundary between the Staurocephalus beds (a) and the Brachiopod beds (b) is to be 
seen. The shale, being accessible in a section made by the river, is cut through by faults. 
In the description (p. 20—23) the layers Dl — 4, C, and Bl — 4 belong to the Stau- 
rocephalus zone, the remaining ones are attributed to the lower subzone of the

paper.
