Addendum to "Ricci-flat holonomy: a Classification": the case of Spin(10)

This note fills a hole in the author’s previous paper ``Ricci-Flat Holonomy: a Classification’', by dealing with irreducible holonomy algebras that are subalgebras or real forms of $\text{mbb}C\oplus \text{mf}spin(10,\text{mbb}C)$. These all turn out to be of Ricci-type.
