Oliva reticulata (Röding, 1798)
40mm

These appear to be variations of Oliva reticulata. Shells up to at least 40mm were observed in the sand at Pura Segara, Melasti and Batuniti.

These darker specimens appear to be the variety known as Oliva reticulata azona.

From Pura Gerombong.

The next five photos are from Tianyar.

The next one was identified on iNaturalist as the adspersa form of Oliva carneola. Animal and shell look a bit more to me like O. reticulata but the exact ID must remain uncertain.
