L. He insists upon the importance of the ovicell in classification, aud 
criticises Gregory’s classification, see (4), showing that some of the so- 
called “ gonocysts ” are really modified zooecia or ovicells. He further 
describes the growth of colonies in the Cyclostomous Polyzoa. See- 
liger (21) discusses their reproduction by budding. 
Kraepelin (11) describes the eating up of the spare eggs by phagocytes 
in freshwater Polyzoa. These phagocytes he had previously described as 
spermatozoa. 
Pergens has a note on species-making in fossil Bryozoa. 
Gregory’s catalogue of fossil Jurassic Bryozoa (4) combines the 
results of previous papers, and will prove a very useful work.
