stones, a series of unfossiliferous strata. As described by Richard- 

 son of the Canadian survey, and Murray and Howley of the New- 

 foundland survey, they are also comformable, but overlie the Levis 

 slates. 



A fault, already traced by Murray and Howley, separates the 

 northern horizontal outcrop of the Sillery at Long Point, Port au 

 Port, from Murray and Howley's Trenton limestones. 



The fauna of these last is certainly like that of the Trenton of 

 New York, but it has a decidedly Newfoundland facies, and its 

 only visible contact is along the perpendicular fault above men- 

 tioned. It contains a great abundance of Bryozoa, Brachiopoda, 

 and reef-building corals, which remind one constantly of the aspect 

 of the Trenton fauna, and has altogether a more modern aspect 

 than the Quebec faunas. It is not yet ascertained whether the 

 Endoceratites found are true Endoceras, but fragments of an un- 

 doubted Gonioceras were collected in considerable numbers in 

 the lower series of these rocks. It seems, therefore, very probable 

 that Murray and Howley are correct in considering the strata at 

 the end of Long Point as the equivalents not only of the Trenton 

 proper, but also of the Black River and Bird's Eye faunas. 



All of the rocks in this part of the island dip away from the 

 mountains in a southwesterly direction, passing out of sight under 

 the watersof the Gulf of St. Lawrence. Thus the outermost strata 

 are, in a general way, more recent than those lying inland or near- 

 er the mountains. The geological position of the Trenton at the 

 end of Long Point, Port au Port, is not far out to sea, but the well- 

 marked fault which occurs between it and the Sillery to the south, 

 or the same narrow point, shows that it is a fragment of an over- 

 lying formation, which, having fallen to its present level, has been 

 preserved, together with the older rocks immediately adjoining. 



The immediate contact of the Quebec limestones and under- 

 lying sandstones and quartzites was seen but not closely exam- 

 ined. 



There can, however, be but little doubt that the quartzites of 

 Bonne Bay, on the east shore of the east arm, lie as described by 

 Richardson and mapped by Murray, directly underneath the 

 Quebec limestones, and are comformable. Whether they are the 

 equivalents of the Potsdam or not can only be determined from 

 Richardson's observations and collections. 



Collections were made at Anse au Loup and Amour Cove in the
