The massive lobate beige sponge was identified as Xestospongia sp., which is probably close to X. exigua, X. subtriangularis, and X. proxima. A voucher specimen (ZMA POR 16161) was deposited at the Zoological Museum of the University of Amsterdam.

    • The ion at m/z 549 was most likely derived from a diol, because the dial does not give this ion peak after Hoffman-type fragmentation. It is likely that the reaction product contained both the diol and the dial.

    • 4 oxidation product gave prominent ion peaks at m/z 576 (HI adduct of the ion at 451), 563, and 451 in the FABMS. The ion at m/z 451 was a methylene homologue of the ion at 437 in the mass spectrum of the oxidation product of 2. These data proved that 2 and 3 have an identical alkyl chain with one double bond and that 3 is one methylene carbon longer than 2 in the saturated chain.
