  We obtain a classification of discrete series representations of odd general
spin groups, generalizing the M{\oe}glin-Tadi\'c classification for classical
groups. Using mostly algebraic methods, available in both classical and the odd
general spin case, we provide a simplified and shorter version of the
classification of non-cuspidal discrete series in terms of the admissible
triples. The presented classification can potentially be directly applied to
many other reductive $p$-adic groups.
