Sometimes a species will come in a range of colours or patterns, these are known as forms ( Latin <i>forma</i>)and some that occur regularly are named. The names have no taxonomic value but the name gives you an idea of what a particular shell looks like. For example, one C. spectrum form is named 'pica' and is a black and white shell so if you see for sale 'Conus spectrum forma pica' you will know what the shell will look like.
Hope this helps,
Dave

Dear Dave, thanks for consultations. Yes it C. spectrum f. pica. I cannot understand with the top. Whether it is possible to carry it to C. spectrum f. petergabrieli or it too C. spectrum f. pica?
