Juveniles?

[17saupe]

I found these shells in Perth, Western Australia.
I suspect the shells are juvenile shells and would love confirmation if they are or not.
I would also love some help on identifying what type of shells they are.

Shell 1 from the anterior to posterior is around 3cm (approx 1.18 inches)
Shell 2 from the anterior to posterior is around 2.5cm ( approx 0.98 inches)

Thanks!!

I think #1 in Strombidae nearly mature if not mature. #2 looks like a cone can't think which one. Won't claim to an expert however.

Thank you so much!! I hadn't even considered any species from that family but I'll look into it a little more.

I appreciate the help,

#1 appears to be Strombus (Canarium) mutabilis, mature or near mature, but beach worn.
I believe #2 is Conus dorreensis, based on the high spire and strongly nodular shoulder. This species has a dark yellowish band around the body whorl when alive, but that color is in the periostracum. Once the thin periostracum wears off dead specimens, the shell itself is white.
