  We report on searches in deep inelastic $ep$ scattering for narrow baryonic
states decaying into $\Xi^-\pi^-, \Xi^-\pi^+, \KS p$ and their charge
conjugates, at centre-of-mass energies of 300 and 318 GeV. No signal for a new
narrow baryonic state is observed in the mass ranges 1600-2100 MeV ($\Xi\pi$)
and from threshold up to 1700 MeV ($\KS p$). The standard baryon $\Xi(1530)^0$
is observed in the decay mode $\Xi^-\pi^+$, and mass dependent upper limits on
the ratio of the hypothetical pentaquark states $\Xi^{--}_{5q}$ and
$\Xi^0_{5q}$ to the $\Xi(1530)^0$ signal are given. Also for the hypothetical
strange pentaquark $\Theta^+$ mass dependent upper limits on $\sigma(ep\to
e\Theta^+X)\times
  BR(\Theta^+\to K^0p)$ are obtained. Finally measurements of the acceptance
corrected ratios $\sigma(D^{\ast}p(3100))/\sigma(D^{\ast})$ for the
electroproduction of the anti-charmed baryon state $D^{\ast}p(3100)$ decaying
into $D^{\ast}$ and $p$ are presented.
