<a href="" target="_blank"><!-- m --><a class="postlink" href=""></a><!-- m --></a> these are Nerita quadricolor to compare with the ones that I think they are another species for one the parietal region is smooth and the spiral cords are thinner than in Nerita quadricolor

Quadricolor to me has thin spiral ribs and less colour pattern, like the two shells bottom-middle and the shell bottom right. The others I am not sure of, they look to me like grossa. As I said, a very difficult and confused complex of Nerites, some consider quadricolor as a synonym of undata.
