!S'.is -1902. No. 28.1 THK CAMBRO-OUDOYICIAN BEDS. 



From Victoria Head in his work previously mentioned, "Palaeonto- 

 logy of the Coasts of the Arctic Lands etc". Etheridge, reports the dis- 

 covery of Madurea inagna LESUEUR, which is an ordinary Ghazy form 

 in the southerly North American regions. 



The locality from which the hulk of SCHEI'S collections of fossils 

 in these regions helong, is Norman Lockyer Island in Princess Marie 

 Bay, outside the mouth of the little northerly branch. Franklin Pierce 

 Bay. The island is formed of limestone with the same N-N-W 

 clip as the beds farther south. The fossils, which lie in a grey-brown 

 limestone which is mostly very compact, but in places more crystalline 

 were according to SCHEI'S diaries gathered on the east or south-east of 

 the island, although no quite precise locality can be given. 



The following forms have been identified: 



Anthozoci. 



Halysites catenulatns var. gracilis HALL. 



In one single specimen we find portions of this coral, not particu- 

 larly well preserved. We can however see the comparatively rectangular 

 section of the coral tubes, which are characteristic of this variety of 

 H. catenulatus L. 



Calapcecia canadensis BILLINGS. 



One colony of a regular rounded form. Greatest diameter 9 cm. 



Streptelasma corniculum HALL. 



Various small specimens occur, mostly less than 2 cm. long. 



Bryozoa,. 



Bryozoans must have been extremely common in the limestone. 

 We find numerous somewhat large pieces - - unfortunately not in a very 

 good state of preservation of a Mesotrypa, which seems much to 

 agree with M. discoidea ULRICH var. orientalis BASSL. * 



In addition there is a small piece of a small ramified form, with a 

 thickness of 35 mm. the structure of which can be studied well, and 

 which agrees entirely with Callopora angularis ULRICH. 



1 I am inclined to believe that the form described by LAMBE (Geol. Surv. Canada 

 1907) as a coral under the name Labyrinthites chidlensis is very closely 

 related to this species.
