Abstract

1. 1. The distribution of labelled leucine to the tissues of mature, sexual triclads was non-random, the greatest incorporation being by the reproductive system and particularly the vitelline tissues. 2. 2. Incorporation into the reproductive system was more marked in semelparous (breed once and die) than in iteroparous (breed repeatedly over several seasons) triclads. 3. 3. No antero-posterior gradients of uptake and incorporation were discovered in either mature sexual or immature sexual or asexual triclads.
