The marine Carboniferous of Nortii-east Greenl. and its Brachiopod Fauna. 591 



than can be ascei4ained from the grouping laid down in the pre- 

 ceding general review. 



If we wish to distinguish and collectively discuss forms that 

 really belong stratigraphically to the same horizon, we must go 

 further into detail, and give those fossils that have been found 

 either in the same stratum at a definitely known level — with a 

 definite and assured statement that they have been discovered in 

 the solid rock — or else those fossils that have been found in the 

 same boulder. 



Of the fossils from the Lower group of beds, the following, 

 therefore, are connected with each other, which were found at the 

 same level in the bituminous limestone with the marl-shales: Spi- 

 rifer siipramosquensis Nik., Sp. rectangiihis Кит., var. alta п. var., 

 Chonetella nasuta Waag. and Productiis simcnsis Tschern., i. е., 4 

 species of 8. All the others were found isolated. 



Of the collections belonging to the Upper group, the specimens 

 N:o 15A, from the Mallemukfjæld, and N.os 197 and 204 from the 

 Eskimo Naze, contain more than one species of brachiopod. 



In boulder N:o 154 were found: Rhynchopora Nikiiini Tschern., 

 Camarophoria cfr. KarpinsJdi Tschern., Athijris Roijssii L'Eveillé, Reti- 

 ciilaria lineata Martin, Strophalosia sp. indet. N;o 2, Productus com- 

 pressiis Waag., Pr. cancriniformis Tschern., and Pr. timanicus Stuck. 

 i.e., 8 species out of 18. Specimen N:o 197 contains 3 species: Pro- 

 ductus boUviensis D'Orb., Pr. pseudohorridus Wiman and Pr. timani- 

 cus Stuck., while specimen N:o 204 contains only 2 species, viz., Rhijn- 

 chopora Nikitini Tschern. and Productus Lovéni Wiman and an un- 

 determined Productus belonging to the semireticulatus group. Special 

 attention must be paid to the forms occurring in specimen N.o 154, 

 when attempting to distinguish from this region a fauna belonging 

 to a definite epoch of the Carboniferous.
