Clessin, 1879, p. 178. Surinam. 
Clessin is giving only South-America as the habitat of 
this species, found in the stomach of a fish. The specific 
name intimates sufficiently its occurrence in Surinam.

(subfossil). 
The Galibi-specimens are very young ones. Among the 
subfossil shells from the so-called ,schelpritsen” (banks 
_ running parallel to the coast and containing mostly marine 
shells), collected by Mr. van Heurn, I discovered many 
valves of this species.
