Remarks.

The type locality was not specified for each species, but is taken from the title of Adam’s paper. "Two examples, one in good condition, of this very finely marked and interesting species were obtained by Mr. Bartlett" ( H. Adams 1867a: 442). Only one specimen is present, of which the index card in the collection states "The specimen, although not registered, appears to be 1867.5.18.4 which was purchased from Bartlett along with other types described at the same time. No specimen can be found with this number. The writings on the board are the same as those on the other specimens puchased at the same time, including the original labels. Locality exactly correct". The specimen, of which the top is damaged, is the figured specimen by Adam and is here designated lectotype (design. n.).

Current systematic position.

Bulimulidae , Drymaeus (Drymaeus) bartletti (H. Adams, 1867).
