Abstract:We investigate the ideal structure of the Toeplitz algebra 
$$ \mathcal{T}(\Gamma) $$
of a totally ordered abelian group 
$$ \Gamma $$
. We show that the primitive ideals of 
$$ \mathcal{T}(\Gamma) $$
are parametrised by the disjoint union 
$$ X $$
of the duals 
$$ \hat{I} $$
of the order ideals 
$$ I $$
of 
$$ \Gamma $$
, and identify the hull-kernel topology on 
$$ X $$
when the chain of orderideals in 
$$ \Gamma $$
is isomorphic to a subset of 
$$ \{-\infty\}\cup \mathbb{Z} \cup \{\infty\} $$
