. The Echo. Mollusks. Figure 9. Typhis coronata, shell. Figure 10. Aspella, cf< A. pyramidalis, shell. The operculum and radula of these forms allies the Typhinae most closely to the Muricinae. The typhine radula is quite small and consists of two typically muricid lateral teeth flanking a simple, five-cusped rachidian tooth. The sharp cusps of the rachidian are all of almost equal length (Figure 11).. Figure 11. Cinelidotyphis myrae, 2/3 of a transverse radular tooth-row. 60.
