Paradoxides lamellatus and P. eteminicus ; and the black shales with 

 Division Id. which is characterised by the sub-fauna of P. abenacus. But 

 T;vhen we check the lithology by the pala'Oiitology we note that whereas 

 only one sub-fauna can be found in the measures on this south shore of 

 the Kennebecasis, one fauna and three sub-faunas as well, characterise 

 the resembling measures in the St. John Basin. Other objections to con- 

 sidering the two sets of beds as quite synchronous will be ajjparent when 

 we come to speak of the sub-fauna at Hastings Cove more in detail. 



Description of the Species. 



About twenty-six species and varieties of the new sub-fauna are 

 described in this article. They belong to the genera Linnarssonia, 

 Acrothele, Agnostus, Microdiscus, Conocoryphe, Paradoxides. Agraulos, 

 Liostracus, Ptychoparia, Solenopleura, Auomocarc, Dolichonietopus and 

 ■Oorypyge. 



Of the species (usually represented by a varietal form) three are 

 Bohemian, two British, twelve Scandinavian, two Olenellus Fauna of 

 the VYestern States, three Olenellus Fauna oftho Eastern States, nine are 

 found in the older sub-faunas of the Paradoxides Beds of the St. John 

 Group. In the above reference to resembling species, some ai"e represen- 

 tative, not identical species, and the comparisons are made in most 

 instances with descriptions and figures of those species, .the types not 

 being within reach of the author. 



BRACHIOPODA. 



ACEOTEETA, Kutorga. 



A poorly preserved example in a phosphate nodule shows the 

 presence of this genus. 



ACROTHELE, Linnarsson. 

 Acrothele Matthewi. Hartt. mut. .aiultioostata. 



A form of this species occurs in the dark siliceous shale, the ventral 

 valve of which is marked by numerous narrow, obscure, radiating 

 ridges. The ridges are seen onlv on the flattened outer two-thirds of the 

 shell. 



A costate variety of this species is found in Ikuid l> of Division 1 of 

 the St. John Grroup, and Dr. Pompeckj has described a form A. qiiadri- 

 lineata from a conglomerate below the Paradoxides Beds in Bohemia 

 The form from Hastings Cove differs fron; either of these in the more 

 numerous, though obscure ridges.
