In sand and clay filling the interior of a Mya, which 

 seems to have heen entoinlted in sifii, arc many micros- 

 copic tests of foraminifera and valves of Cythere and 

 Cy theridca. Among the former were the following species: 



Pol i/sf 0)11 I'll a critijxt. 



Noniomna scapha (and var. hihratlorica).

 rrisjja is much more abundant than the other species. 

 Nonionina scapha conies ne.xt in this respect, and all the 

 others are rare. The material also contains numerous 

 spicules of siliceous sponges. 



The above fossils may be regarded as characteristic of

It would also appear that, as elsewhere in Canada, the

 probable that many of the travelled boulders of Lauren-
