fig. i or, more commonly, the two lateral bands may be continuous proximally forming 

 a single U-shaped body of considerable length. 



In Catnptoplites giganteus the zooecia may contain single, very long, coiled, almost 

 tangled, bodies, which are more slender and less coarsely granular than those of 

 Notoplites drygalskii. 



The distribution of the bodies in the colony and their position in the zooecia appear 

 to bear no special relation either to the reproductive phase of the colony or to the state of 

 the polypide. They usually stain less readily than the other tissues with borax carmine. 



Except, perhaps, in Beania magellanica, they seem to me to suggest parasites rather 

 than organs of the Polyzoa, and I have therefore shown those in Notoplites drygalskii to 

 Dr H. A. Baylis and Professor Doris Mackinnon. Both authorities found it impossible 

 to come to any decision about them without fresh, properly fixed material, but both 

 suggested very tentatively that they might perhaps be Protozoa. Dr Baylis reported 

 that they were certainly not worms. 



ADDENDUM 



Dr Silen's paper on Cheilostomata Anasca from Japan and the Bonin Islands (Ark. 

 Zool. Stockholm, 33A, 1942) did not reach me till August, 1942, when this report, which 

 was completed in July, 1941, was in page-proof. He describes a new species of Catnp- 

 toplites of the C. bicornis group, extending the range of the genus to Japan, and a new 

 species of Tricellaria of the T. sympodia group. 



Professor Marcus's work on Bryozoa from Brazil (Bol. Zool. Sao Paulo, 5, 1941) 

 did not reach me till April, 1943. He discusses the distribution of Caberea boryi.
