Reeve 1861 : volume 13, Cyclophorus , pl. 15, species 69. Japonia (Lagochilus) confluens - Kobelt 1902 : 40. Current generic position. Cyclotus Swainson, 1840 Type locality. Borneo. Type material. Syntype NHMUK 20170355 (1 shell; Fig. 4F). Remarks. The species description by Pfeiffer did not indicate the number of available specimens and did not include an illustration. Only one set of shell measurements was given in the original description. Reeve (1861) re-published the description and figured one specimen from the Cuming collection. The NHM collections contain a lot containing one shell with Pfeiffer's handwritten label giving the species name and collection locality. This figured shell matches well with the measurements given in the original description and the figure in Reeve (1861) .
