Thais sp ID help

[mark]

Hello,
 
I’m sorry if ihave stupid questions but I would like to sort mycollection and have a lot of shell which make me trouble.  Some shell waiting for id for long time but Ifound a picture on the net what similar and found a lot of another what different and can’t make decision what is the truth. Some shell I think my id was wrong and I would like to make the correction.
 
If it is not problem I would like sometimes ask your help.
 
For example this Thais sp (cca 4 cm) (first I thought it’s Thaisvirgata buti it have longer spines…) sometimes I found a similar picture which said me it is a Thais jubilaea but wrote to the Google found a lot of different pictures.
 
What do you think about it?
