[Apr. 10, 



The following is the list as determined by Mr. Etheridge : — 



In speaking of the beds on Red Deer River, I referred to the fossils 

 found at this place as showing the existence of forms which are in 

 Mexico associated with those of the Saskatchewan, and in every case 

 found in the proximity of the lignite-beds. Thus in particular we 

 have Cytherea Tescana, common to the Saskatchewan and Mexico, 

 and Trigonia Bhnori, common to Mexico and the Pacific coast. This, 

 owing to the very imperfect state of our knowledge and the limited 

 extent of the collections, is probably to be considered as merely an 

 indication of the agreement that may yet be established. The green 

 sandstone beds at the base of the series which contain the lignite 

 seem to have been deposited originally on the surface of the igneous 

 rock, which was probably submarine, so that its surface, chilled by 

 the water, easily broke up into the masses that compose the con- 

 glomerate-like breccia, the cement of which has been derived from the 

 tufas that were deposited on its surface. On the shoal thus formed 

 the greensand beds had been deposited, enclosing the molluscous 

 remains. The whole has since been repeatedly disturbed, and some 

 of the lower beds have undergone partial fusion by more recent out- 

 bursts. 



The sandstone is sometimes quite horizontal, but at others quite 

 vertical for a little way, and is only found as patches all round the 

 promontory and north side of Departure Bay. 



Three hundred yards from the shore in the channel that passes 

 between Newcastle Island and the Fossil Point, is a row of islands 

 composed of very fine conglomerate that might be termed " gravel- 

 stone," in beds that dip S.S.E. at 15°. These beds contain small 

 fragments of carbonized wood. 



A quarter of a mile further on, in the direction of the dip on the 

 north end of Newcastle Island, there are high cliffs of sandstone, 

 which preserve the same direction. They seem to be rather more 

 disturbed than the strata that form the islands in the channel, but 

 this appearance is exaggerated by the great amount of false bedding. 

 The strata of sandstone continue to preserve the same direction of dip 

 all along the coast of Newcastle Island, but gradually becoming 

 more horizontal towards the southern extremity. On the west side 

 of the Island at Exit Channel occur the seams of coal, the lowest of 

 which has been worked to a considerable extent, while the existence 

 of the other has only been found by boring. The outcrop of these 

 two seams has been ascertained on the east shore of the island, where 



* It is probably from this place that the fossils were procured to which Meek 

 and Hayden refer in a notice of the coal of the Pacific coast, contained in the 

 Pacific Bail. Rep. vol. vi., whore they say that among the fossils from Vancouver 

 Island a number occur in a green sandstone matrix, which have a strong Jurassic 

 aspect
