﻿Notes on Fossils from Prince Charles Foreland. 157 



an extremely deep sinus, which extends down to the front. 

 The ratio of width to height is about 4 : 2'o. Shell sub- 

 stance very thick (3 mm.); ornamentation not known, but 

 there are faint indications of reticulation on the slightly 

 concave brachial valve. 



As regards its afl&nities, this form should probably be 

 placed in the group of M. typica, Waagen, but it is much 

 larger than the latter, and its visceral part is not so elevated 

 above the hinge-line ; the shell substance is also much 

 thicker. 



The genus has already been recorded from the Arctic 

 regions by Professor Tschernyschew. In the Table, p. 360 

 of his work on the Brachiopods of the Ural and Timan, 

 M. typica var. sept entr ion alis, Tschern., is indicated as present 

 in the " Spirifer Limestone " of Spitsbergen and the Bear 

 Islands ; it is therefore interesting to note the occurrence 

 in these regions of what may prove to be another species of 

 this genus. 



Genera Indetekminable. 



Ehynchonellids and (?)Athyrids are present, but only as 

 fragments, so that they cannot be determined, even generic- 

 ally, but they are mentioned here in order to give a complete 

 idea of the fossils collected. 



The fragment of whitish-grey siliceous limestone (Xo. III.), 

 apparently the cast of a large Actinoceras, yielded the fol- 

 lowing fossils : — 



Fusulina cf. cylindrica, Fischer. 

 Calicinal cast of Zaphrentoid coral. 

 Casts of Crinoidal stems. 

 Cf. Chonetes huchiana, de Kon. 



Of these fossils, the most interesting, from a stratigraphical 

 point of view, is Fusulina cf. cylindrica. Although not 

 quite identical with the characteristic form of the species 

 as described by Fischer de Waldheim, its occurrence in 

 Prince Charles Foreland is rather important, as it may prove 

 useful for correlation purposes. In 1882 Messrs Nathorst
