On our last voyage relocating our vessel from Geraldton to Shark Bay, we had good weather and had time to have a look around the area to the west of the Southern Zuytdorp Cliffs and northwest of Kalbarri. It became obvious that in addition to praeclara, both rosselli and ketyana are quite different to specimens collected from other areas. The ketyana are very small with sizes varying from 38 to 46mm, have modest to non existent basal flanges and typically have dense pepper spot dorsa. Basal colour is quite variable with some having bright orange lutea like bases while others have black basal trim as is the case with this specimen.
The are absolutely gorgeous little shells. Given they are quite different and restricted this area I have decided to use the form name "zuytdorpensis" to refer to them. This specimen is graded Fine+++/Gem- due to soft dorsal folds.
