Finet (2001): This deep-water species is mentioned from the Galapagos in Keen (1971). Gemmula esuriens Dall, 1908, a synonym, was also cited from near the Galapagos Islands by Dall (1908), giving the distribution and known records of his new species; the type locality however is not the Galapagos, but “Gulf of Panama, in 1270 fathoms”. No other material has ever brought further evidence of the occurrence of the species in deep waters around the Galapagos Archipelago.
