find a better place elsewhere in connection with the topo- 

 graphical description of the island. 



II. Large blocks of a black fossiliferous limestone, hard 

 and crystalline, and containing an abundance of carbonace- 

 ous matter. 



The most conspicuous fossil here is a large Bryozoon 

 belonging to the genus Stenopora ; the other fossils are 

 all Brachiopoda, and although scarce, attain a large size. 

 This rock was found in situ in the low ground that separates 

 the main mountain range from the isolated peak at the S.E. 

 end of the island, known as Saddle Mountain. The exact 

 geological age of this rock cannot be inferred from the fossils, 

 as they may be either Carboniferous or Permo-Carboniferous. 



III. A fragment of a whitish-grey siliceous limestone, 

 friable on the decomposed surface, compact where fresh. 



The specimen is apparently a fragmentary cast of a large 

 Cephalopod, within which are many smaller fossils. This 

 was found in the same locality as No. II., but not in situ. 

 Upper Carboniferous (?). 



IV. Two blocks of a grey, siliceous, and highly fossiliferous 

 limestone, having when weathered a yellow surface, crowded 

 with the remains of Fenestellid Bryozoa. 



The rock is extremely hard and compact, but not crystal- 

 line. It is a very good example of a ''Bryozoa Reef and 

 contains many other fossils besides Bryozoa. Its locality 

 is the same as given above, but it was not found in situ. 

 Dr Bruce, however, believes that its outcrop can be traced 

 along the southern part of the western coast of the island. 

 Permian. 



Y. Slabs of hard grey shale, containing remains of dico- 

 tyledonous leaves of Tertiary age. 



Of these, the best specimens have been examined by 

 Professor Nathorst, the authority on the fossil flora of the 

 Arctic regions, who states that "they must have been 

 collected from the lower plant-bearing horizon at the base of 

 the Tertiary Series." He adds that he will examine the speci- 

 mens more closely, and send further information about them. 



Found in situ in the northern part of the east coast and 

 at Peter Winter's Bay.
