Hab. Carr or Goop Horr. High Constantia (Benson, 1846). 
Cape Town (Layard). Wynberg (Lightfoot), Somerset Hast (Miss 
Bowker). King Williamstown (Miss Ross). Grahamstown (Farqu- 
har). Port Elizabeth (Crawford).

Very widely distributed over most parts of the globe. 
Mr. B. B. Woodward has identified specimens from Wynberg, 
Pretoria, Grahamstown, Port Elizabeth, and Pietermaritzburg as 
excentrica, and it is probable that the other occurrences of Vallonia 
in South Africa refer to the same species. Of course, many early 
reports of pulchella, such as Benson’s in 1850, were made long 
before excentrica was differentiated.
