Double checking taxonomy of cerithium

[wateryworld]

Interesting.  Different sources say different things, some that you are right, while others that I am right.   

The information I found claiming stercusmuscarum is now muscarum is from here --->
<!-- m --><a class="postlink" href="http://www.marinespecies.org/aphia.php?p=taxdetails&id=473612&nbsp;">http://www.marinespecies.org/aphia.php? ... 3612&nbsp;</a><!-- m --> The shell in question has a black and white speckled colouration to it.


The second one, going from cerithium vergatus to rhinoclavis rhinoclavis, is also from that site and is here --->
<!-- m --><a class="postlink" href="http://www.marinespecies.org/aphia.php?p=taxdetails&id=473045">http://www.marinespecies.org/aphia.php? ... &id=473045</a><!-- m -->
This shell is completely white.

Many of the shells I've looked up on that site match info on other sites, as I always cross-reference several sites at once.  Frankly, I don't know how people are supposed to know all of jack if every source available has as much potential to be completely wrong as the next source.  It's absolutely ridiculous.
