Hello,
I cannot identify these cones. They are all from the same place : Indonesia, Sulawesi.
Thanks for any help

1- 17mm



2- 42mm



3- 55mm



4- 80mm



Thank you,
Pierre.

#1 I am not sure, maybe a juvenile arenatus?
#2 looks like spectrum
#3 looks like one of the magus forms
#4 is distans.

Thank you very much Dave!
