30     native terrestrial mammals, 2 native marine mammals (N) 
17     native bats 
11     introduced or naturalised species (I)
4       terrestrial island mammals (Isl)
22     cetaceans found in and around our waters
9       vagrant mammals: 4 bat species and 5 pinnipedia (found only occasionally)
