The marine Carboniferous of Nortli-east Greenl. and its Brachiopod Fauna. 525 



275 metres. Dark gray limestone, alternating with black, bitu- 

 minous shales. 



240 — Dark (gray) limestone, alternating with a black, 

 bituminous, shaly limestone. 



200 — Gray limestone and red limestone (resembling the 



Ambigua limestone of Beeren Eiland.) 

 100-130 ~ Shales. 



3) The Conglomerate section. 



At the following levels characteristic rocks have been observed 

 in the solid rock: 



220 metres. Sandstone. 



200 — Dark gray limestone, alternating with bituminous 



shales. 



190 — Sandstone. 



185 — Limestone with traces of bituminous partings. 



150 — Sandstone. 



130 — Light limestone. 



120 — . Conglomerate. 



4) The profile communicated by Jarner to Nathorst has the fol- 

 lowing appearance; 



500 — 275 metres e Limestone rich in corals. 



275—240 — d" Fossiliferous sandstone. 



240—200 — d Sandstone without fossils. 



200—130 — с Conglomerate. 



130—105 — b Gray shale. 



105—100 — a Fine and soft black shale. 



If we compare these conflicting statements, it will still be pos- 

 sible, however, to come to some result respecting the actual order 

 of the strata, and also to see the origin of Jarner's profile and 

 what is intended by it. The statements cannot be brought into full 

 agreement, however, but it is evident that, to obtain his profile, 

 Jarner has adopted the sequence of strata given in Koch's section
