Points of Special Interest. (1) In Stirparia the first zooecium of a tuft has the character of a primary zooecium (p. 470). * [In view of the difference of opinion as to whether this Phylum should he called Bryozoa or Polyzoa (see Proc. Linn. Soc. 1911, p. 61) I have not interfered with the preference of the author. — Editoe.] t Communicated by Cyril Ceossland, M.A., B.Sc, F.Z.S. X Vov explanation of the Plates, see p. 532.
