Below attached specimens were collected from soft bottom - Persian Gulf. 10 m Depth. Sharing any idea regarding species identification will be very much useful to me...
The species you want to classify this time are difficult. I'm interested in worldwide Turridae and so before try to identify the genus they belong. The first is Sp3 very similar to Vitricithara that is a Caribbean genus and Pyrgocythara the come from West Africa and is a species in my collection. At last I must search in the species that was established in the beginning of 19° century by Melvill & Standen or by Townsend. I send you two photos of this two species very similar to your.
Dear/Dr. Soroor, Presently, I am working on the Cretaceous bivalves but as per my knowledge sp 1 belongs to Genus Malletia if taxodont series is present at dorsal part. sp2 belongs to Arcidae family and Sp3 and sp4 are related to mytilidae.
