PALÉOZOOLOGIE ET PALÉOPHYTOLOGIE 169 



author's object in this preliminary discussion « is to call attention to the 

 sponges from the Burgess shale and to leave to future investigation the col- 

 lecting of material and study of the sponges of the Cambrian ». 



The classification of Zittel is mainly folio vved, under the sub-class Sili- 

 cispongise, with additions of forms unknown to him. Under order Monacii- 

 nellida Zittel and sub-order Halichondring Yosmaer, are the new gênera 

 Tuponia, Tahakkawia, Wapkia, Hazelia, Corralia, and Senlinelia, with 15 

 new species. Under the family Suberilidse are two new gênera Choia, Hamp- 

 (onia, and Pirania, with 5 new species. Under order Hexaciinellida 0. 

 Schmidt, sub-order Lyssacina Zittel, and family Protospongidœ Hinde, 

 is the new genus Kiwetinokia, with several new species. Under sub-order 

 Dictyonina Zittel and new family Vauxininse Walcott are four new species 

 of Vauxia. Under the family Ociaciinellidse Hinde is the new genus Eifelia, 

 with one new species, and under sub-order Heieraclinellîda Hinde and new 

 family Chaneelloridse Walcott is the new genus (Ihaneelloria, with four 

 new species. 



Gomparison is made with récent spongies and considérable range of va- 

 riation is observed. The Métis shale sponge fauna of Province of Québec is 

 correlated with that of the Burgess shale in British Golumbia, five identical 

 gênera being found, Halichondrites, Choia, Proiospongia, Diagoniella, and 

 Kiwetinokia, and three hâve not been seen in the Burgess shale. The descrip- 

 tions and figures comprise fauna from many localities besides that of the 

 Burgess shale, inclucling, Alberta, Utah, Province of Québec, Georgia, Ida- 

 ho, New-York, Alabama, Pennsylvania and Nevada.

The plant- remains described in this memoir were for the inost part col- 

 lected by the N. Z. Geological Survey, but other collections were also exa- 

 minée!. The âge of tbe rocks in which they occur vary from Triasso-Rheatic 

 to Neocomian. No Palœozoic plants hâve yet been found in New Zealand, 

 and, according to Arber, the statement that Glossopleris occurs in incorrect. 

 Hence, he thinks, New-Zealand was never par of Goudwanaland. It appears, 

 however, that Seward regards Arber's genus Linguifolium as very closely 

 relatée! to, if not generically indentical with Glossopleris. The floras occu- 

 ring at Mount Potts and Glent Hills (Canterbury), are considérée! to be 

 of Rhaetic âge. Those of the Hokanui Hills (Southland), and Ovvaka Creek 

 (Otago), are doubtfully assignée! to the Rheatic. From the Malvern Hills 

 (Canterbury), Mokoia near Gore (Southland), and Mataura Falls (Southland)
