TEN DAYS' DREDGING AT OBAN. 

 By the Rev. A. M. Norman, M.A. 



A line of railway has been now opened to Dalmally, and 

 Oban has thus been brought within very easy reach of the tourist 

 visiting Scotland. This deservedly favourite place, on the western 

 coast, is likely each year to become more frequented. It has 

 struck me, therefore, that a list of the Mollusca which, during a 

 very short visit, vrere observed in the land-locked waters close to 

 Oban, might not be without interest to your readers.
