Aspidosiphon (Aspidosiphon) gosnoldi Cutler, 1981  

Most of these specimens have been collected inside gastropod shells resulting in a coiled trunk after fixation. Consequently it is difficult to obtain accurate measurements. This species has a distinct anal shield, composed of randomly arranged flat units, not tightly packed, of approximately uniform size. The distal hooks are compressed bidentates hooks followed by unidentate ones. Aspidosiphon gosnoldi has been reported only in the West Atlantic Ocean in subtidal zones.
