Professor Bonney — Specimens from the Canadian Rockies. 297 



of Laggan), is represented by a light-coloured fine-grained quartzite, 

 which was collected from directly below the summit and on its 

 western side. It might very well be from one of the older 

 Palasozoics. 



In Professor Collie's collection, as in that made by Mr. Whymper, 

 well-preserved organisms are rare.' Several of the limestones in the 

 former are in the same mineral condition as those described from the 

 latter one, so that it seemed needless to have them sliced, and I may 

 refer to what I have already said.- No doubt a closer search will 

 discover occasional localities with well-preserved fossils such as 

 that on Mount Stephen, but I anticipate that in this part of the 

 Eocky Mountains (nearly 60 miles in length), as in some of the 

 Alps, there will be considerable districts of sedimentary rock in 

 which fossils are absent or barely recognizable.

Fig. 1. — Slab of quartzite, with spine-shaped markings. About 7 inches by 



3|- inches. 

 Fig. 2. — Slab of quartzite, with bilobed marking. About 5 inches by 2J inches

 Fig. 3. — Slab of quartzite, with mounds. A very Kttle has been excluded from 



each end of the block in taking the photograph. It is about one -third' 



linear of the original.

Note on some Fragmentary Eemains op Fossils from the upper 

 PART OF Mount Noyes (Canadian Kockies). By H. Woodward, 

 LL.D., F.R.S, — The specimens (reproduced in the accompanying 

 diagram about twice natural size) lie scattered over the weathered 

 surface of a thin and somewhat worn, hard, black, slaty rock, in 

 character not unlike that so rich in Trilobites from Mount 

 Stephen (B.C), (see Geol. Mag., 1902, Dec. IV, Yol. IX, 

 pp. 502-505). After much hesitation, on account of the imperfect 

 nature of the materials at my disposal, I venture, with some! 

 reserve, provisionally to place these remains as follows : —

 four pairs of furrows, a raised and rounded anterior border, one fixed cheek, ; 

 and indication of the left eye and cheek are also seen upon the surface 

 of the slab. A fragment of another head is present, but is too imperfectly 

 preserved for determination.
