108 The Ottawa Naturalist. {Nov. 



Cardium dccoratuin Gnik. 



Three years later, in company with Dr. Hasell, of Victoria, 

 I collected at Mount Tolmie all of these species and an additional 

 Cardium now no lon^^er living in these waters, C. decoraium 

 Grnk. (My diagnosis was confirmed by Dr. Dall, of Washington). 

 The first localitv is at an elevation of about thirty feet above 

 present sea-level ; that of the second at about one hundred and 

 ten. according to the new contour map of the Saanich Peninsula, 

 — the greatest height at which I have found similar marine 

 shells. 



Passing over many minor localities mention may now be 

 made of a typical one at the shallow and much diminished Lost 

 Lake, near the foot of the prominent monadnock called Cedar 

 Hill or Mount Douglas. 



This lake lies at an elevation of eighty-three feet At a distance 

 of about four miles from the- Victoria post office. In 1894, 

 when ^ilr. Nicholson, the owner of a large farm bordering on 

 the lake, was extending his drains, a typical condition of things 

 was found, as described at the beginning of this note, with 

 all of the species of marine shells mentioned, lying under a thick 

 layer of imperfectly formed peat. 



At the present time the Canadian Northern Railway iS 

 endeavoring to find a footing for their road-bed through the 

 lake by driving piles through the shallow bottom. At the last 

 time of my visit they had reached a depth of more than one 

 hundred feet without finding sufficiently firm groimd. On 

 the side of a shallow cut here I noticed Macoina nasuta and 

 inquinata, in addition to the species alreadv noted. It was in 

 this region, though nbt clearly identified, that Mr. Richardson 

 collected his specimens referred to.
