Rhiostoma   Benson, 1860

Type locality.

Near Kina Balu [Mount Kinabalu, Sabah, Malaysia]; Palawan [Palawan Islands, Province of Palawan, Mimaropa Region, Philippines].

Type material.

Syntypes NHMUK 1894.5.23.1 from near Kina Balu (1 shell; Fig. 3B), NHMUK 1895.12.5.34 from Palawan (1 shell; Fig. 3C).


The original description gives a set of shell measurements and figures of two specimens, so this species is clearly based on more than one specimen. There is a type lot (two shells) with differing registration numbers, one specimen NHMUK 1894.5.23.1 is from R Hungerford ex. Mr. Boxall from Kina Balu and the NHM registration book states “Type”. The other shell, NHMUK 1895.12.5.34, in the same box was collected by Mr. Whitehead from Palawan and agrees well with Godwin-Austen (1893: fig. 1b, c). These two shells form part of the type series and are considered as syntypes.
