OF THE FIRTH OF FORTH. 69 



Forth, were of very great importance to us. These con- 

 tributions are subscribed (M.) in the list. As of peculiar 

 interest we may mention his discovery of Lepton squamosum 

 in shell sand at North Berwick. This species belongs to 

 the south and south-west coasts of England, and the only 

 Scotch locality mentioned in Jeffreys' " British Con- 

 chology" is Oban (Barlee). Mr M'Murtrie informs us that 

 he has found the shell at Bamborough, and this, we believe, 

 is the only place recorded where it has been found on the 

 east coast.
