Ancey’s locality, ‘‘ Disappointment Key,” is probably a slip. On 
labels in the Layard collection the spelling is Disappointment Vlei, 
which for many reasons seems the more likely name.

After examination with a strong lens, I am unable to find any 
specific difference between the type set of this species and examples 
from Pietpotgietersrust, which appear to be acicula (Miill.). 
As advena, Ancey, and ovampoensis, M. & P., were founded on 
shells gathered by the same collectors in the same locality, the two 
species are in all probability identical, but it has not been possible to 
compare the types.
