like schists and limestone conglomerates. From a few inches up to a 

 couple of yards in thickness these conglomerates and schists, con- 

 tinuously interstratified, build up a series GOO to 900 feet in thickness, 

 interrupted by two compact beds of yellowish-grey dolomitic limestone, 

 about 150 feet in thickness. These are again overlain by a series 

 similar to the underlying one, excepting that here the limestone 

 conglomerates exceed the schists. 



In a detached block, in all probability originating from one of the 

 two 150-foot beds, were traces of fossils, of which only one, Leptoplastus 

 sp., can be identified. In another detached block whose mother rock 

 is not known was found Anomocare sp. It may be said with certainty 

 after the finding of these fossils that this series contains deposits of the 

 Cambrian age. 



The second series of conglomerates is overlain by a light greyish- 

 white limestone in a bed some 300 feet in thickness observed in the 

 midst of the section of Cape Victoria Head. Indistinct Orthoceras, 

 Lichas, and Syrnphysurus assign this limestone to the Lower Silurian 

 period. 



Above the Orthoceras-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 limestone, of which certain layers 

 are fossiliferous, and gave an Asajfkus, 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 somewhat abrupter, in 

 the limestone beds of Norman Lockyer Island. A fauna with Halij- 

 sites sp., Zaphrentis sp., Orthisina sp., Rhyncliondla sp., Leperditia sp., 

 Illcenus sp., etc., 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 superincumbent 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 limestone con- 

 glomerate dipping from the heights of Cape Harrison are cut off in the 

 strike by a limestone, dark grey in colour and broken into a breccia. 



Answering to this series, which chiefly consists of coast formations, 



* For the determination of animal fossils mentioned here and later I am 

 indebted to Dr. I. Kjtcr, who has been good enough to make a provisional 

 examination of the material.
