Dear Bill,
After my last message [#21238], I found at the same place some other "usual" Bullina lineata with the two red spiral lines on the shell. A couple during the night of 6 december 2007 and several (more of six) the night of 18 december 2007 spawning. The front of the head shield is similar.I hope that it is enough to call it B. lineata.
Locality: Etang-salé, Two metres, Reunion Island, Indian Ocean, 6 and 18 december 2007, By night. Length: 18-20 mm. Photographer: Hugues Flodrops.
Best regards.
Hugues.

Dear Hugues,
Although I suspected the animal in your other message was just missing a red line it's a bit hard to be sure without further indications. These more 'normal' animals make me pretty sure it is B. lineata. The shell is a bit more inflated than the ones I commonly see in Sydney, but looking at shells in the museum's collections suggest they often get more inflated as they increase in size, and yours are larger than we normally see in eastern Australia.
It's nice to get a photo of a pair mating.
Best wishes,
Bill Rudman
