Prefatory Remarks. 



In 1895 and 1897, extensive collections of fossils from the " Lower 

 Shales", or " Division C", of the coal-bearing rocks of the Cretaceous 

 system, at Skidegate and Cumshewa inlets, were made by Dr. C. F. New- 

 combe, of Victoria, V.I. A full series of the choicest specimens in these 

 collections has been lent to the writer for study and comparison, and some 

 of the best of them have been generously presented by Dr. Newcombe to 

 the Museum of the Survey. Those which the writer has seen add eight 

 new species of marine invertebrata (viz., three of ammonitidpe, four of 

 pelecypoda, and one of brachiopoda) which are described and figured in 

 this paper, to the fauna of the Lower Shales, besides some interesting 

 fossil plants, which have yet to be studied. Some of the fossils collected 

 by Dr. Newcombe, also, are much better specimens than had previously 

 been obtained of species that had already been described. Thus, one 

 particularly fine specimen (which has been presented to the Museum) 

 shows that the fragments upon which Spiroceras Carlottense was based 

 (in the third part of this volume) are portions of a large Turrilites ; and 

 others that Acanthoceras spiniferum is probably distinct from A. Stolicz- 

 kanum (Gabb). 



The revised list of species at the end of this paper shows that eighty- 

 nine species of marine invertebrata are now known from the Lower Shales 

 besides five that are too imperfect to be determined specifically. Of the
