In Chapter XVI of " The Mediums' Book",  Allan Kardec presents a tabular view of the principal varieties of mediumship.  Regarding the whole set of divisions, he writes: 

"We have grouped the different varieties of mediums according to similarity of causes and effects, but without offering this classification, as in any way absolute.  Some of them are frequently met with; others, on the contrary are rare, and even exceptional, and we have been careful to mark them as such. The indications thus given have all been furnished by Spirits, who moreover, have reviewed and carefully revised our list and completed it by various observations, so that it may be said to be entirely their work."  

Some of these we have already covered (see General Classifications, Types of Physical Mediums, Types of Intellectual Mediums, Healing Mediums) or will cover in other sections (i.e. Good and Imperfect Mediums); however, it shall be pointed out here that he does list additional divisions. We make reference to these here, to point out that such varieties exist and have been classified, and we refer you to "The Medium's Book" for more information.

Please see Chapter XVI of "The Medium's Book" for the definitions of these varieties of mediums (Keep in mind that these varieties include those which involve communications provoked by inferior spirits):
