Found by J. C. Dacie near Margate in September, 1914, 

 and considered by J. W. Taylor to be indigenous 

 (Journ. of Conch., xv, 1916, p. 11; & Manual, 

 iv, p. 65). Probably introduced in the young state 

 with food on the farm for poultry, on the other side 

 of the hedge where the specimens were found (teste 

 W. J. Wintle, 1924). 



The record that this species occurred fossil in the 

 Ightham Fissure (Proc. Malac. Soc. Loud., ii, 1897, 

 pp. 242-43) was an error.
