#1 is in the family Neritidae. #3 could be Cerithiidae, or a Morula or some other small Muricid.  I agree with all your other family designations, but all of these except perhaps one of the Nassarius are juveniles and positive ID is going to be difficult.  <span class="petit">--Last edited by Paul Monfils on 2009-03-03 21:01:51 --</span>

Hi, it would be very helpful to know where they were collected. I don't know of any keys ( I find those too laborious to use anyway)but you could try the website gastropods.com
Cheers,
Dave

thanks Paul and Dave.

Paul, which Nassa are you refering to as a juvenile?

Dave, they were collected off the coast of Penang island in Malaysia.

Nr. 2 could be a juvenile Notocochlis gualtieriana

AFAIK there is generally no easy way to tell whether the shell is a juvenile or not. For some groups like Cypraea it is easy to tell apart a juvenile and an adult because of the characteristical shell shape and/or colors. For other species there are only hints like a thin shell or a thin lip or short spines, but all these could just as well belong to the normal appearance of that particularly species.

I have a juvenile N. gualtieriana just like yours one from Malaysia (Langkawi). I wasn't able to identify it until recently when I got an adult N. gualtieriana specimen from Australia.
