‘Internodes usually unicellular, the zocecia arising one from the 
upper and back part of another, by a corneous tube, all facing the same 
way and forming dichotomously divided branches of an erect phytoid 
zocecium. The zocecium at each bifurcation geminate; each zocecium 
with two lateral, usually trilocular, processes (ale). Ocecia either sub- 
globose and terminal or immersed, and placed below the orifice of a 
zocecium in front.’—Busk, ‘ Chal. Rep.’ p. 10. 
Mr. Busk describes the eight Challenger species in the collection, and 
figures only a portion of them. The first four belong to the section 
a. Fenestrate, the other to the section § 3. Vittate. Since the publica- 
tion of the ‘ Brit. Mus. Catalogue’ (1852) many new species have been 
added to Mr. Busk’s original list, and described and partially figured by 
Australian students. In the following list I have given the whole of the 
species known to me, and Mr. Waters has been able to add to the recent 
species many new fossil forms from the Australian tertiary beds, details 
of which will be found in my fifth ‘ Brit. Assoc. Rep. on Fossil Polyzoa,’ 
1884, Montreal.
