Dolichometopus occidentalis, Matthew. 

 Bathyuriscus pupa, Matthew. 



Xeolenus, (n. gfen.) Matthew. 1899. 

 N. granulatus, Matthew, 

 Oryctocephalus Walkeri, Matthew. 



Besides the above, Dr. Matthew also records the occurrence 

 at Mt. Stephen, of the following forms from the Walker col- 

 lection : 



.\XNELID.\. 



Hj'olithes, sp. 



Trilobita. 

 Ptychoparia cordillera;, Rominger. 

 Bathyuriscus Howelli, Walcott. 

 Neolenus serralus, Roming-er, sp. 

 Doropyge Darwini, Walcott, sp. 

 Zacanthoides spinosus, Walcott. 

 ^^g'/R'a (Og-ygopsis) Klotzi, Rominger. 



Dr. Matthew then gives a very careful analysis of the genera 

 obtained from the Mt. Stephen horizon, and the percentage of their 

 occurrence, with the use of comparative tables. He concludes by 

 making the following statement : " The Mouut Stephen Fauna is 

 essentially Upper Cambrian. " This places the horizon of the Mount 

 Stephen trilobite bed (at an altitude of between eight and nine 

 thousand feet above sea-level) a higher position than had pre- 

 viously been assigned to it.

In this paper Dr. Matthew discusses the succession of faunas 

 in Newfoundland, and combats the " conclusion so universally 

 adopted" that the Olenellus zone occurs below the Paradoxides 

 zone. He reverts to the arrangement of the succession of strata 

 of E. Billings in 1864. In this connection Dr. Matthew writes : 

 " The impossibility of finding the genus Olenellus 0/- its uccompanv- 

 ing fau7ia in the strata of the Eastern Provinces of Canada, below 

 Paradoxides (which strata were eventually found to contain a 

 considerable fauna of trilobites) led him in 1892 to propound the 

 view that Olenellus might be contemporaneous with Paradoxides 

 but confined to a different habitat. This surmise was, in a sense,
