Type locality: “ Ile Acmène , Nouvelle-Caledonie ( Marie )”. Label: “N. Cal.”; “Nou, Caled.”, in Brot’s handwriting. Dimensions: “Long. 77 mill.; diam. maj. 45”; figured specimen herein H 88.0, D 47.2, W 6.7 . Type material: MHNG-INVE-64837, one possible syntype (ex Marie, Brot coll.). Remarks: Gassies did not state on how many specimens his description was based, but described this taxon on the basis of material collected by Marie. According to Neubert et al. (2009: 86) the taxon was based on an undetermined number of specimens, and they showed that Gassies’ name is a junior homonym of Bulimus hindsi major L. Pfeiffer, 1841 . The specimen in the Brot collection is, according to the label in Brot’s hand, originating from E. Marie. It is, however, possible that this material reached Geneva via Crosse, as the original label seems to bear his handwriting. The specimen is thus considered as possible type material. The current systematic position follows Neubert et al. (2009) . Current systematic position: Bothriembryontidae , Placostylus porphyrostomus monackensis (Crosse, 1888) .
