Show the list of category codes and names for the checklist, fulllist, and detaillist species list operations. Any of the category code values can be used to limit the species list results; '1', 'Mammals', or 'Mammal' will return the same Mammal species list. A species list for multiple categories can be returned by seperating the categories by a comma. For example, 'mammals,birds' to get the species list for Mammals and Birds.
