An imperfect head that is probably referable to this species, though it 

 shews little more than a cast of the glabella, which is proportionately 

 wider in front than that of average examples of C. Niagarensis from the 

 Anticosti grotip of Anticosti. The Canadian Calymenes that E. Billings 

 identified with C. Blumenbachii are now usually referred to four species, 

 viz., C. senaria, Conrad, from the Trenton limestone ; G. callicephala, 

 Green, from the Hudson River group ; C Niagarensis, Hall, from the 

 Niagara, Guelph and Lower Helderberg formations, and from the Anti- 

 costi group ; and C. platys. Green, from the Corniferous limestone. 



Encrinurds, sp. iudet. 



One pygidium. The axis of this pygidium is long and slender, with 

 sixteen or seventeen annulations, each of the six anterior ones being 

 minutely tuberculated. There are nine lateral ribs on each side, without 

 any tubercles. 



A. 4.— FROM THE WINISK EIVER. 

 Collected by Mr. W. McInnes in 1903. 



ANTHOZOA. 



Tetracoralla. 



Streptelasma, sp. indet. 



A small slab of limestone, with two specimens in longitudinal and one 

 corallum in transverse section, on its worn and exposed surface. These 

 sections shew only the general shape, which is straight and conical with 

 an obtuse base, and some of the septa, with a few of the dissepiments 

 between them. 



From an exposure thirty one miles above the mouth of the river. 



Hexacor-vlla. 

 Favosites Gothlandic0s, Lamarck. 

 From the same exposure as the preceding species, two small colonies, 

 on the same piece of limestone ; and from an exposure thirty four miles 

 from the mouth of the river, one specimen. 



BRACHIOPODA. 



Trimerella, sp. indet. 



Two worn casts of the interior of pedicle valves, which shew only the 

 general shape, and obscure casts of the platform vaults or umbonal 

 chambers. 



From loose blocks at or near the mouth of the river.
