Some errors in the paper by Choudhary, Yousuf, Atta-ur-Rahman, Anjum, Fun & Ali [Acta Cryst. (2005), E61, o3523–o3525] are corrected. In the Abstract, the text `The rigid molecule consists of eight fused rings involving three The spiro-fused γ-lactone rings are in half-chair and envelope conformations. The spiro-fused γ-lactone rings are fused to a cyclohexene ring, which is in a half-chair conformation.' is corrected to `The rigid molecule consists of eight fused rings involving two The spiro-fused rings D and E are in half-chair and envelope conformations. The spiro-fused γ-lactone rings are fused to a cyclohexene ring F, which is in a half-chair conformation.' In line 11 of the Comment, an atom label is corrected so that the text reads `(c) oxidation of the C18 methyl group'.
