  A delay analogue of the box and ball system (BBS) is presented. This new
soliton cellular automaton is constructed by the ultra-discretization of the
delay discrete Lotka-Volterra equation, which is an integrable delay analogue
of the discrete Lotka-Volterra equation. Soliton patterns generated by this
delay BBS are classified into normal solitons and abnormal solitons. Normal
solitons have a clear relationship to the solitons of the BBS with K kinds of
balls. On the other hand, abnormal solitons show various types of novel soliton
patterns, which have not been observed in almost all known BBSs. We obtain them
by numerical experiments, and then construct {\tau}-functions of them
analytically in 1-soliton cases.
