I 



and more nearly parallel to the laminae. In its 

 outline it reminds one of the problematical Eozoon 

 from the Hastings group at Tudor, Ontario, referred 

 to in the text. 



Should time permit, I hope to have all the speci- 

 mens in our collections illustrating this interesting 

 and primitive type examined and described. In 

 the meantime I may merely remark that a near 

 modern analogue would seem to be the gigantic 

 arenaceous Foraminifer Neusina Agassizi, Goes, 

 dredged by Alexander Agassiz in the Pacific, and 

 described in the Bulletin of the Museum of Com- 

 parative Zoology (Vol. xxiii.. No. 5, 1892). The 

 modern form, it is true, is flat and foliaceous ; but 

 some of the old species approach to this shape, and 

 if we suppose the little cells of Neusina to represent 

 the tubes of Cryptozoon, and the carbonaceous 

 matter of the latter to be the remains of the 

 chitinous stroma seen in some specimens, the general 

 resemblance will be very close. 



The whole subject of these peculiar Stromato- 

 poroid forms extending from the Upper Cambrian 

 to the Laurentian, deserves a full and careful 

 investigation, for which I am endeavouring to 

 collect material.
