Remarks.

The original taxon label has been corrected to Bulimus gratus , in a different ink. However, also a label with this name in Pfeiffer’s handwriting has been glued to the board. It may be noted that Lea’s name ( Bulimus columbianus ) is sufficiently different to retain Pfeiffer’s original taxon name. On the front side, a later hand has written ”Venezuela”, which may be seen as a further precision to reflect the later political-administrative situation. Breure and Borrero (unpublished data) could not recognise this species in the Colombian material they studied.

Current systematic position.

Bulimulidae , Drymaeus (Mesembrinus) columbiensis (Pfeiffer, 1855).
