ifThe ordinal taxon "Heterogastropoda" is utilized here as a convenience only. Kosuge (1966) proposed the suborder Heterogas- 

 tropoda to accommodate the Triphoridae, Mathildidae, Architectonicidae, and Epitoniidae, which he regarded as distinct from the 

 Taenioglossa and Steonglossa. Haszpruner (1984, 1985) separates the Architectonicidae and Pyramidellidae as the Allogastropoda, dis- 

 tinct horn the Architaenioglossa (the Valvatacea, Cyclophoracea, and Viviparacea); the Neotaeniogbssa (rissoids, cerlthlids, hipponiclds, 

 strombids, cypraeids, naticids, and tonnids); the Heteroglossa (ccrlthiopsids, triphorids, epitoniids and eullmids); and the Stenoglossa (the 

 Neogastropods, including muricids, cancellarids, and the Conacea). (jhis table continued on next page.)
