Hi Diana,
Briefly and roughly:
When an individual describes a genus, he uses a specific species as his
model, one that he thinks best represents the genus he is describing. It
exemplifies all the characteristics that he ascribes to that new genus.
That is the type species.
You will also see "type specimen" which means the actual shell from
which the species it belongs to was described. There are various other
types.
