I've got a mixed pack of squash seeds from Seeds of Italy, one of which is Serpente di Sicilia. I've been examining the seeds with the aim of picking out roughly similar varieties to grow together, and one type is quite differently shaped to the others - thicker, and darker than a normal squash family. I know cucuzzi is a slightly different variety and wondered if anyone here could tell me do these seeds match my description (I can do a photo sometime if that helps!)

many thanks
Me
