In 1894, Jose Rizal sent (from Dapitan) to Möllendorff (who was in Manila at that time) specimens of large sea snails known as tun shells together with some specimens of a species of small freshwater snails stored in glass vials. The species of small snails were later named Oncomelania quadrasi by Möllendorff in 1895 in honour of Don José Florencio Quadras, a Spanish malacologist who was also based in Manila at that time.
