Distribution.

Found across Peninsular Malaysia ( Maassen 2001). Elsewhere, in Singapore, Thailand and Indonesia ( Ho 1995, Panha and Burch 2005, van Benthem Jutting 1941, 1959).

Remarks.

Shell dextral, rarely sinistral. Shell vary greatly in height, rib density, number of whorls (7 to 8) and aperture thickness within and between populations. After examining large samples from our study sites, we concur with Tweedie in Laidlaw (1949) that it is not possible to separate Diplommatina canaliculata von Möllendorff, 1886 from Diplommatina nevilli . The specimens labelled as Diplommatina mirabilis in Davison (1991) are actually Diplommatina nevilli .
