## Abstract A mollusk‐specific toxin, TxVIIA, having potent paralytic activity was isolated from the venom of sea snail __Conus textile__ (Fainzilber M et al., 1991, __Eur J Biochem 202__:589–595). The structure reported above was based upon amino acid analysis and the Edman degradation. We have re
