SOME LOCAL DETAILS. I57 



///. — A nticosti. 



On the island of Anticosti Messrs. Hyatt, Verrill and 

 Shaler found Saxicava ardica in clay at an elevation of 

 fifteen feet above the level of the sea. 



The late Mr. Kichardson of the Geological Survey, to 

 whom we owe most of our knowledge of the geology of 

 Anticosti, had previously noticed, in his Eeport for 1857, 

 the occurrence of travelled boulders and of beds of clay, 

 holding rounded fragments of limestone, and forming 

 cliffs sixty to seventy feet high, but makes no mention of 

 any pleistocene fossils. In 1885 the island was visited by 

 Lt.-Col. Grant, of Hamilton, who made interesting collec- 

 tions, which he kindly presented to the Peter Eedpath 

 Museum of McGill University.* 



The following are extracts from a letter of Col. Grant, 

 referring to the localities of the fossils and the mode of 

 their occurrence : 



" The post-tertiary shells were first noticed in patches 

 of blue clay in the south-west of Anticosti, in the bed of 

 Becscia river, close to its mouth. When first seen, I 

 thought it probable that they had been washed in by a 

 high tide from the Gulf, but, on proceeding a short 

 distance up stream, I found the clay and shells in situ, 

 capped by a considerable thickness of drift, boulders, etc., 

 in the river bank. The shells appeared to be unusually 

 large. I collected a considerable number. Many got 

 subsequently broken in rough weather. 



" The pleistocene clay (Leda clay), occurs also in the 

 bank and bed of Chaloupe river, and it is exposed along 

 the cliff within a few miles west of the South-west point
