Ceraurus sp. 



A fragment of the head of a trilohite, showing the anterior two 

 thirds of the glabella, belongs to a Ceraurus sp., yet without seeming 

 to agree completely with any known species as far as can be seen. 



These fossils are probably of Niagaran age, but no more detailed 

 correlation is possible. 



The different sedimentary series just mentioned all belong to Schei's 

 serie A, the distribution of which he has shown on his preliminary map. 

 He states also that "The brown limestone of the capes stretches from 

 South Cape westwards to Sealbay in Hellgale, but is interrupted at the 

 Little Sandbank, where the tectonic disturbances have brought to the 

 surface the underlying conglomerate-series and even the Archaean rock." 



Series B. 



Respecting the rocks of the Goose Fjord Schei writes: "On the south 

 side of Reindeer Valley the limestone of the capes (series A) crops out 

 with a gentle dip towards the norlh-north-west; but on the north side 

 of the valley there was a section of dark schists (series B), lying con- 

 formably upon the beds of brown limestone. This section contained, 

 especially in its highest and its lowest strata, thick layers of pure 

 dark-coloured limestone, which was often fossiiiferous. In both Reindeer 

 valley and Seal bay, where this section was also observed, we collected 

 a tolerably large number of specimens, a cursory examination of which 

 has resulted in the identification of some fifteen species, mdnAingFavosites, 

 Strophomena cf. eugli/pha, large numbers of Meristella, Rhyncho- 

 nella cf. borealis, Pentamerus cf. galeatus, Spirifer cf. elevatus. The 

 age of this section of series B is consequently Wenlock. 



The uppermost strata of series B, crops out at the cape which lies 

 north of Tunnel Valley in Walrus Fjord. First, there is a black shale 

 with fossils of a species of Monograptus and Leperditia cf. phaseolus. 

 Upon that lies a bed of fragmentary limestone, with Favosites, Stropho- 

 mena cf. peden, Atrypa reticularis, Pterinea cf. Sowerhyi. In one 

 locality in Goose Fjord at the same level in the stratigraphical order, we 

 found Favosites cf. Hisingeri, Fav. gotlandicus. Thecia Swinderenana, 

 Spirifer elevatus, Spirifer cf. crispus, Strophomena corrugatella Da- 

 vids, and species of Pterinea. Thus the uppermost division of series B 

 would appear to belong to the Ludlow group. The total thickness of 

 the series is about 1000 feet."
