216 CKUISE OF THE NEPTUNE 



observed in the midst of the section of Cape Victoria Head. 

 Indistinct Orthoceras, Lichas and Symphysurus assign this 

 limestone to the Lower Silurian period.' 



' Above the othoceras-bearing, light-coloured limestone bed 

 are some less extensive strata of alternating limestone and 

 quartz-sandstone, and finally a 100-foot bed of close brown lime- 

 stone of which certain layers are fossiliferous, and gave an 

 Asaphus, traces of other Trilobites and some Gasteropods.' 



' Following the direction of the dip to the north side of 

 Princess Marie bay we find it again, though seemingly some- 

 what abrupter, in the limestone beds of ]STorman Lockyer island. 

 A fauna with Halysites sp., Zaphrentis sp., Orthisina sp., 

 RhyncJionella sp., Leperditia sp., Illoenus sp., &c., assigns this 

 limestone to Lower Silurian. It is again found with its fauna 

 at the base of Cape Harrison ; in this case with a thick super- 

 incumbent bed of marly sandstone, quartz-sandstone, and finally 

 extensive limestone conglomerate. This also occurs near the 

 shore in Cape Prescott, indicating by its presence in the strike 

 of the limestone of Norman Lockyer island the disturbance 

 undergone by these tracts. 



' The line along which this disturbance took place is refound 

 on the west side of .Franklin Pierce bay, where the beds of lime- 

 stone conglomerate dipping from the heights of Cape Harrison 

 are cut off in the strike by a limestone, darK-gray in colour and 

 broken into a breccia.' 



In another place Schei hints that the rocks of the Cape Raw- 

 son beds, consisting largely of dark shales and impure lime- 

 stones, found along the northern parts of the eastern shores of 

 Ellesmere, may be of Triassic age, in sharply folded troughs of 

 the older rocks, and consequently much younger than Cambrian, 

 to which age they were referred by Fielden and De Ranee. 



Writing of the Silurian beds found on the southern coast of 

 Ellesmere, Schei describes them as answering to the northern 

 series, and their occurrence is as follows :
