Art. XVI. — Cambrian Fossils from Mount Stephens, North- 

 west Territory of Canada / by Charles D. Walcott.* 



The announcement of the discovery by Mr. Otto J. Klotz 

 of a group of Cambrian fossils at Mt. Stephens, near the line 

 of the Canadian Pacific railway, and a description of some of 

 the species by Dr. C. Rominger, appeared in July, 1887.f 



Dr. Rominger describes one new genus of the Trilobita, 

 Embolimus, and five new species, and also mentions two other 

 species of trilobites, several brachiopods, a species of Hyolithes 

 and what he thinks may be a graptolite. There is no attempt 

 made to give the stratigraphic position of the fauna in the 

 Cambrian system, by comparison with published sections and 

 descriptions, or to compare the species with similar forms that 

 have been described from the Cambrian strata of the Rocky 

 Mountains. He states that it was his intention to visit the 

 locality, and, if he has done so, we may receive more informa- 

 tion in relation to the occurrence of the fauna there. 



Mr. Klotz presented to the IT. S. Geological Survey a small 

 collection of fossils from Mt. Stephens, and, through the kind- 

 ness of Professor J. F. Whiteaves, Paleontologist of the Geo- 

 logical Survey of Canada, I have before me some very fine 

 specimens, from the same locality, collected by Mr. McConnell.
