At the suggestion of Professor Spencer, I have undertaken to 

 continue the examination of the fossil polyzoa found in the 

 Tertiary strata of Victoria, and thereby supplement the work of 

 the late Dr. Macgillivray, whose valuable Monograph appeared 

 in the Ti-ansactions of this Society ; and I would remark that it 

 is with the greatest pleasure I do so, now that I have time to 

 devote to the work, for from 1866 until 1884 1 studied the 

 recent- polyzoa, and during all that time received great assistance 

 from Dr. Macgillivray. Afterwards my official duties neces- 

 sitated constant travelling, and I had to discontinue working at 

 them ; so I gave my undescribed material to him, and I have 

 pleasing reminiscences of evenings spent at Bendigo with him 

 in the examination and discussion of new species. 



Thanks to the kindness of Mr. 'J\ S. Hall and Mr. J. Dennant, 

 I am in possession of material collected from many localities, 

 which has yielded me, so far, the majority of the species already 

 recorded, and also many new forms. The present paper deals 

 with some new species of Catenicellidfe, together with some 

 ocecia (of known species) which have not hitherto been described. 



Though I am quite aware of the evil of making unnecessary 

 species, I have described the fertile zocecia of Catenicellai and 

 Strophipora which I have found as new species, because, as all 

 the fossil specimens are in single internodes, in consequence of 

 the corneous connecting tubes being destroyed, it is impossible 

 to determine whether they are ooecia of known species or not ; 

 for those in the i^ecent and, presumptively, also those in the 

 fossil species differ considerably from the form of the normal or 

 infertile zoa'cia. In the Claviporell^e and Caloporella; it is 

 different, as the otiecia in these genera are adnate upon, or
