18'.i,s -190"2. No. 2S.| THE CAMBRO-OHDOVICIAN BEDS. 9 



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

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

 covery of Madurea magna Lesueur, wiiich is an ordinary Ctiazy form 

 in the southerly North American regions. 



The locality from which the bulk of Schei's collections of fossils 

 in these regions belong, 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 

 dip 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: 



Anthozoa. 



Halysites catenulatus 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 corniculiim 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 3—5 mm. the structure of which can be studied well, and 

 which agrees entirely with Callopora angularis Ulrich. 



1 I am inclined to believe tliat ttie form described by Lambe (Geol. Surv. Canada 

 19U7) as a coral under the name Labyrinthites chidlensis is very do.sely 

 related to this species.
