Summary

A difference of possible physiological significance is reported in the chemical nature of the green integumentary pigment of the echiuroidBonellia viridis, the proboscis of which contains the known bonellin (1, R=H) as the major constituent, while the body skin is mainly pigmented by an isoleucine conjugate, neobonellin, formulated tentatively as2 (R=H) by spectral and chemical data.
