These shells are all of marine origin, and belong to the two classes 

 of Gasteropoda and Lamellibranchiata. Thev belong to species still 

 existing in our Canadian waters, in the Gulf of St. Lawrence, along the 

 Atlantic coast, also in Greenland and Norway, and in other parts of 

 the world. One of them, Saxicava rugosa, L., is even found on the 

 Pacific slope, both living and fossil (Dr.G. M. Dawson). Maconia cal- 

 caria, Chemnitz, was also found in the Cumberland-street excavation in 

 stratum No. 5, at a subsequent time. This species and Notica a^nis^ 

 Gmelin, are new to the list of Post Tertiary forms published by the 

 club (1884). 



In conclusion, the Leaders beg leave to solicit the co-operation of as 

 many of the members interested in geology as possible in collecting the 

 material necessary to frame up a systematic work on the Geology of 

 Ottawa. It may take years and years of labour ; every little helps 

 Facts are what we need at jn-esent, and when a good topographical map 

 of the district has been published, it will be easier to lay down the geo- 

 logical boundaries than at present. 



The increased attendance at the sub-excursions is veiy encouraging 

 and most gratifying to the leaders, and they sincerely hope that the 

 manifest interest taken in geological matters during the past season will 



be kept up in years to come.
