Note AZ — INTRODUCTION TO PART III.
Reading edition
There is some doubt as to the proper name of this species, which may not be the one originally described as Membranipora lacroixii by Andouin. I follow Busk and Hincks in my identification (see Cat. Polyzoa Brit. Mus. ii, p. 60, and Hist. Brit. Polyzoa, p. 129). Levinsen calls it M. hippopus, sp. nov. (see Morphological and Systematic Studies on the Cheilostomatous Bryozoa, p. 144; Copenhagen, 1909).
