description: A search for the production and non-standard decay of a Higgs boson, h, into four taus through intermediate pseudoscalars, a, is conducted on 683 pb-1 of data collected by the ALEPH experiment at centre-of-mass energies from 183 to 209 GeV. No excess of events above background is observed, and exclusion limits are placed on the combined production cross section times branching ratio, ξ^2 = σ(e+e- --&gt; Zh)/σ_{SM}(e+e- --&gt; Zh) x B(h --&gt; aa)x B(a --&gt; τ^+τ^-)^2. For mh &lt; 107 GeV/c2 and 4 &lt; ma &lt; 10 GeV/c2, ξ^2 &gt; 1 is excluded at the 95% confidence level.
