and buds.

colour in masses when dead. Sci. Goss. 1879, p. 113. 
Codonosiga hotrytis^ Ehrb., var., (3) p. 566, fig. 37. The flagellum ends 
abruptly, not in a point. It is described as terminated superiorly by four 
cirri, sometimes united by a membrane, besides the flagellum. The 
cirri are homologous with the complete cup of the ordinary form of 
collar-celled Monads.
