Content-Type: multipart/alternative;

None of the descriptions I have of this shell indicate the presence of a
periostracum.  However, many I've seen do have what appears to be a  light
to very heavy, brushy periostracum.  Does Ilynanassa trivittata have a
periostracum or am I seeing some other growth?
