I think you're referring to a cons cell. This is the basic component of LISP 
and Scheme lists. A Scheme function that returns a list will actually return a 
cons cell which is, generally, a structure with two fields: the CAR field 
points to the first element in the list. The CDR field points to another cons 
cell representing the remainder of the list or a null value (the empty list: 
()) to represent the end of the list. Basically it's just a convenient way of 
implementing linked lists.
