TheDictyone- The Dictyonema fauna, like that of the Tremadoc group, has so far 

 been recognized only in the valley of McLeod brook, and is found in 

 similar gray and dark gray shales. The species are : 



The Peltura 

 fauna. 



The Parab- 

 olina fauna. 



Dictyonema flabelliformis Eichw. 

 Acrotreta bisecta. 

 Schizambon priscus. 

 Leptobolus gemmulus. 



Lingulella concinna. 



L. cf. lepis. 



Linnarssonia cf. Belti. 

 Monobolina refulgens. 



The Peltura zone gives a more varied fauna, which is contained in 

 similar slates with some thin limestone bands.

 Peltura scaraboides. Wahl. 



There seems to be a somewhat abrupt transition from thin flags and 

 sandstones below the Peltura horizon to the assise which contains that 

 fauna. It is marked on East bay by the occurrence of a calcareous 

 sandstone full of phosphatic lumps and nodules, and with ripple marked 

 layers. This would indicate deposition in shallow water near a shore 

 line, whereas the fossils of the underlying Peltura beds indicate rather deep 

 water and quiet seas. Unless there is a break in the succession here, such 

 as we have not observed elsewhere, these thin flags and phosphatic layers 

 should represent tho Parabolina zone. The fossils are : 



Lingullella Isevis var, grandis, and var. lens. 



The band below, Assise C. 2, c. has yielded fossils in the valley of the 

 Mira river, where there are a few species of small size, viz : 



Lingulella radula, var. aspera. 

 Leptobolus flumenis. 



Lingulepis rotunda.
