in their relation to the surrounding rocks more nearly represent coal

Fig. 3. Passage Beds between Subdivisions C. and D., East Side Allifoed Bay. 



Lowest beds of On the opposite side of the Alliford Bay synclinal, the lowest beds 

 of C. skirt the point and islands lying off it to Flowery Island. On the 

 latter the lowest bed of the felspathic sandstone is brownish-grey and 

 sometimes quite hard, and rests with an appearance of slight uncon- 

 formity on the bluish-grey trappean rock of D. This irregularity of 

 junction is, however, no more than might be expected to occur between 

 beds very dissimilar in character, and the idea that it represents a 

 break of importance or true unconformity appears to be negatived by 

 other circumstances. The junction of Subdivisions C. and D., which 

 varies thus a little in character from place to place, but the conditions of 

 which remain on the whole uniform, is again well shown on the north 

 side of the inlet at the point next west from Image Point. It is also 

 seen at a locality four miles up the channel which leads from South 

 Bay to the west coast, where the rocks of C. seem to form a little 

 broken synclinal, with steep dips, and strike nearly parallel to the 



Broken anthra- direction of the passage. Grey felspathic sandstones are here inter- 

 bedded with dark argillites, all much hardened, and holding on the 

 north side of the fold a little anthracite coal, the fragments of which 

 are bounded by small faults by which the rocks are here dissected. 

 No estimate of the thickness or character of the seam at this place can 

 be formed, and the coal is only interesting as showing that the rocks 

 continue thus far at least to maintain their coal-bearing character. 

 This locality was one of which Mr. Eichardson was informed, but had 

 not time to visit. 



Fossiiiferous Subdivision C. is throughout characterized by the great abundance 



character of C. of fossi i s> * These occur in both the sandstones and shales, and fre- 

 quently are specially abundant in the calcareous nodules, of which each 

 one in some places contains an Ammonite or other form. The rocks form 

 a synclinal in Alliford Bay, and fringe the north-eastern part of Maude 



* The fossils described by Mr. J. F. Whiteaves in Mesozoic Fossils, Vol. I., Part 1., are almost 

 exclusively from this horizon. Those collected by me during the summer of 1878 are not referred 

 to in this report, but will be described in a succeeeding part of the volume to which reference is 

 here made.
