Cyclophorus cantori (Benson, 1851)
“I have thought it advisable to introduce this species here, in order that it may accompany the three preceding species and that immediately following, which, equally with it, belong to the same division of Pfeiffer's subgenus Cyclophorus. The shell forms part of a collection of Penang and Malay species, of which Dr. Cantor entrusted the publication to me, together with some interesting drawings of the inhabiting mollusks, which, I hope, will now shortly see the light.” (Benson, 1851)
