Two auricle shells (Diotocardia Order) are families of gastropod shells that possess primitive characteristics such as: two auricles in the heart; two gills with a double row of filaments; and nerve cells in the foot not concentrated into ganglia. The interior of the shell has a layer of mother-of-pearl. The more advanced forms may display an interior that is porcelain-like.

Gastropods (Class Gastropoda) contain the snails, conchs, and similar snail-like animals. There are about 105,000 species of gastropods. This class is divided into several separate orders:

    Sub Class Streptoneura (57,000 species)

      Order Diotocardia:   Two sets of organs
      Order Monotocardia:  One set of organs
    
    Sub Class Euthyneura   (48,000 species)

      Order Cephalaspidea: thin shells, etcetera
      Order Nudibranchia:  sea slugs        
      Order Pulmonata:     snails and slugs

Mollusks (Phylum Mollusca) are a large and varied group of animals. Some species are found on land; others are found in freshwater; many are found in the oceans of the world. The most familiar mollusks have an external shell surrounding a soft body. Well-known examples of mollusks are snails and clams. The major classes are as follows:
  
   Ablacophora:                  Worm appearing
   Polhyplacophora (Amphineura): Chitons
   Scaphopoda:                   Tusk Shells
   Gastropoda:                   Gastropods
   Bivalvia (Pelecypoda):        Clams, etcetera
   Cephalopoda:                  Octopus, Nautilus
   Monoplacophora:               A recent discovery
