in ihe same paper to appear in the calciferous of IMiilips- 

 burjjfli on tlie Canadian frontier. Trof. Seely informs me 

 in a private letter that he lias since recognized in the 

 Chjiini>lain Valley what appear to be two additional 

 species of Cryjitozoon. 



Cri/jUozooii JJorralc, Dawson (Fig. 1). — A (piite distinct 

 and very interesting sj)ecies was obtained in 1(S88 by Mr. 

 E. F. (Jhambers, of Montreal, at Lake St. .lohn, l*.Q., a.sso- 

 ciated with fossils of Trenton age. It consists of a mass 

 of cylindrical or turbinate branches, proceeding from a 

 centre and also budding laterally from each other. Each 

 branch shows a series of lamiiuc concave upward. The 

 spaces between the thin lamina' are tilled with a very tine 

 granular material, in which are canals, less fre(]uent 

 straighter and more nearly parallel to the lamina- than in 

 the typical species. This species is remarkable for the 

 slender and coral-like shape of its branches, for its 

 resemblance in general form to the disputed specimens 

 resembling Eozoon from the Hastings (probably Huronian) 

 of Tudor, Ontario, and on account of its being the latest 

 known occuri-ence of (Jryptozoon. It was very shortly 

 described and commented o\) in the " Canadian Jlecord 

 of Science " for 1S8D. 



Ci\i//>(ozoon Occidcntale, s.x. — So far our si)ecimens of 

 Cryptozoon have been Ujtper Cambrian or Ordovician, but 

 I)r. C. I). AValcott, in his memoir on the Fauiui of the 

 Lower Cambrian, mentions at p. o'jO that in the (irand 

 Canon section in Arizona, there are unconformablv under- 

 lying the Lower Cambrian " 12,000 feet of unaltered sand- 

 stone, shale and limestone," which may be regardeil as 

 l're-cambrian,and probably in whole or in part represent- 

 ing the Kewenian of Lake Superior and the Ftcheminian 

 of Southern New lirunswick. In these beds, 0,500 feet 

 below the summit of the section, he found " a small Patel- 

 loid or Discinoid shell," a fragment probably of a Trilobite, 

 and a small Hyolithes, in a bed of bituminous limestone.
