From another locality, and probably somewhat lower horizon, 

 are abundant specimens o^ Fsiloplujton and Cordaitcs angustifoUa, 

 as well as a lycopodiaceous cone, probably new. 



Lastly, he noticed the discovery, by Mr. F. Bain, of North 

 River, Prince Edward Island, of several species of certain fossil 

 plants in portions of the Red Sandstone formation of that Island 

 considerably higher in stratigraphical position than that in 

 which they were previously known to occur. The effect of this 

 would be to require us to recognise portions of the sandstone 

 hitherto regarded as Triassic, as being really Permian. We thus 

 have apparently both in Prince Edward Island ; and in Virginia 

 true Permian beds holding the fossil plants characteristic of that 

 formation. 



Dr. Osier presented some notes supplementing his paper on the 

 Canadian Fresh-water Polyzoa read before the Society in January 

 1877. He directed attention to the following points : 



1st. The occurrence of a species of Cristatella which was 

 found in great abundance in the small lakes drained by the 

 Riviere du Loup (en haut), Quebec. This is the most highly 

 organized of all the Polyzoa and is capable of a slow, snail-like 

 movement. 



2nd. The occurrence of an additional species of FlumateUidce, 

 P. diffusa of Leidy. 



3rd. A winter ovum or statoblast presenting certain peculiari- 

 ties in structure and in the form and arrangement of the annular 

 spines, which serve to separate it from the ova of the PectinafeUa 

 or Cristatella. It probably belongs to a new species. 



4th. The Rev. Thomas Hincks, F. R. S., described, in the 

 "Annals and Magazine of Natural History," a supposed Ptero- 

 branchiate Polyzoon from Canada, sent to him by the late Prof. 

 Hincks, of Univ. College, Toronto. The general description of 

 this corresponds to the Pectinatella magnijica, except in the 

 arrauo'cment of the tentacles, which were borne on two distinct 

 erect lobes, and not disposed in a horse-shoe figure. Dr. Osier 

 was of opinion that there had been a slight error in observation, 

 and that the species was the Pectinatella. He was confirmed in 

 this by the fact that he had himself taken the specimen to Prof. 

 Hinks, when a member of his Botany class, and so far as ho 

 remembers, it presented the characteristics which he afterwards 

 learned were peculiar to the Pectinatella.
