Dear Devendra - It's all covered by mud ... impossible to identify. I need a "clean" photo. Regards, Gianluigi

I agree with you that it is in the Nassaridae, but that is about as far as I can go.

 Until and unless u upload a new pic. without mud it will be difficult to identify. There is no surety to say Nassarius sp. 

Hi Devendra,

possibly in the Nassariidae, but impossible to get a reliable determination without clean material showing shell characters.

SALUTI,

Vittorio

OK, here I'm uploading clear images of this species.

Thanks.

It could be  something like Nassarius reeveanus (Dunker, 1847) complex!, but  ....

Best. Gianluigi

I am agree with glanluigi, it is nassarius reeveanus.

Blind thought is impossible in case of research work. This gastropod is fully covered with mud. I can say only this is gastropod.
